Hi,
does JKQtPlotter support plotting multiple series with different scale/axes (and show multiple Y axes)?
ex: https://doc.qt.io/qt-5/qtcharts-multiaxis-example.html
(from qtCharts)
if not, any pointer on how to go about adding this feature (for a coming pull request)?
Hello. The subject.
Corresponding to the code:
class JKQTMATHTEXT_LIB_EXPORT JKQTMathText : public QObject {
protected:
/** \brief base font size in points */
double fontSize;Font size in JKQTMathText is set with points, that is platform dependent, as Qt for a long time is not accurate in this question. I did a lot of applications where were necessary to see the same picture on all devices, and I was forced to calculate fonts' sizes by hands and set them in pixels.
Thanks.
The utility function 'std::string jkqtp_format(const std::string& templ, ...)' uses a reference 'templ' which doesn't work at all with va_start. Every call gets a different result.
My environment: Windows 10, VS2017
Turning off the cmake option JKQtPlotter_BUILD_INCLUDE_XITS_FONTS causes the following error on windows (MSVC 2019, Qt 5.14):
jkqtmathtext.obj : error LNK2019: unresolved external symbol "int __cdecl qInitResources_xits(void)" (?qInitResources_xits@@YAHXZ) referenced in function "public: __cdecl JKQTMathText::JKQTMathText(class QObject *)" (??0JKQTMathText@@QEAA@PEAVQObject@@@Z)
Most likely caused by the following line in jkqtmathtext.cpp:
Q_INIT_RESOURCE(xits);The latest CMake change works on macOS, but not on Linux:
$ cmake -DCMAKE_INSTALL_PREFIX=$CONDA_PREFIX ..

I run into a problem with a error QWidget: Must construct a QApplication before a QWidget, which crashes down the Qt Application.
The following is how I run into the problem.
// profile.h
#ifndef PROFILE_H
#define PROFILE_H
#include <QWidget>
#include "jkqtplotter/jkqtplotter.h"
#include "jkqtplotter/graphs/jkqtpscatter.h"
class Profile : public QWidget
{

public:
Profile(QWidget *parent = nullptr);
Profile();
void show(std::string &name);
private:
JKQTPlotter* plot;
};
#endif // PROFILE_H
// profile.cpp
#include "profile.h"
Profile::Profile(QWidget *parent)

{
}
void Profile::show(std::string couplename)
{
plot=new JKQTPlotter(this);
QHBoxLayout *layout=new QHBoxLayout;
this->setLayout(layout);
layout->addWidget(plot);
// omitted: code for plotting
plot->zoomToFit();
}
Profile *p = new Profile(this);
p->show(this->couplename.toStdString());
this->ui->tabWidget->addTab(p, "name");
I came across the example in the JKQtPlotter/examples, but I am still hard to figure out whether it is problem with QT or JKQtPlotter. Thus, an issue is raised here for some kind instruction. What's more, an example to add JKQtPlotter to a QTabWidget would be very helpful to someone with the same purpose.
Many thanks for your consideration!
Yours,
Sincerely
When running most examples, for example the "ui" one, there are lots of errors printed into the terminal of the type:
##SEARCHING ";"
##SEARCHING ";" : SEARCHING IN "XITS" [unicode]
##SEARCHING ";" : SEARCHING IN "XITS" [winSym]
##SEARCHING ";" : DIDN'T FIND!
What does that mean? How can one fix that?
I use Ubuntu 18.04.
Hi I ran into a problem.
In logscale if the values are so small there is couple of 0 values shown more than once in Y axis like that how to avoid that? Also if you doo zoom operations it can be more or less zeros.
Can the heatmap use following smooth options?
from kk.front() to kk.at(0)
in four places.
As far as I can see, it's not possible to define & use an arbitrary palette for image plots.
Looking at the code, it seems that a few changes to JKQTPMathImage would support this, making use of the JKQTPMathImageUSER_PALETTE option. Would it be OK if I sent a pull-request to show you what I mean?
PS - thanks for writing a great library!
I install JKQtPlotter using:
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=$HOME/ext/jkqtplotter/ ..
make
make install
Then when building my application, my CMakeLists.txt contains:
# Qt
find_package(Qt5 COMPONENTS Core Widgets PrintSupport Svg Xml REQUIRED)
# JKQtPlotter
find_package(JKQTCommonLib REQUIRED)
find_package(JKQTMathTextLib REQUIRED)
find_package(JKQTPlotterLib REQUIRED)
The way it should be possible to build my application is:
cmake -DCMAKE_PREFIX_PATH=$HOME/ext/jkqtplotter/ .
But it fails to find the JKQtPlotter cmake files. Instead, one must do:
cmake -DCMAKE_PREFIX_PATH=$HOME/ext/jkqtplotter/lib/cmake .
Then everything works.
By looking at how other libraries do that, they seem to put the cmake files into $PREFIX/lib/cmake/JKQTCommonLib/. When I manually create lib/cmake/JKQTCommonLib and move the files there, then cmake automatically finds them. It fails because some paths are not adjusted correctly, but it shows how to fix this problem. One also has to create directories JKQTMathTextLib and JKQTPlotterLib.
What I don't know is how to modify the CMake build system in JKQtPlotter to do this automatically.
Note: I actually create a Conda environment and install JKQtPlotter into it. CMake picks up any library out of the box from the Conda environment, except JKQtPlotter due to the problem I reported above. It would be really nice to fix this so that things work out of the box.
Hi @jkriege2 ,
I am very eager to try this out, but I am facing the following build error while trying to build on macOS Catalina (v 10.15.5):

Please let me know if there is any fix/workaround for this. Also let me know if you need more info from my side.
I am trying to get JKQtPlotter into Conda and I got it building on Linux and macOS, but I can't get it to build on Windows. Here is the PR:

Why it compiles for x86 & x86_64 but not others thank you very much need help I wanna use in my graduation project.
Not sure if Iam missing some thing, but Iam piloting very large data sets of float's and can't afford to transform the data as it will use to much memory. The JKQTPDatastore class is nice, but it only seams to operate on double's far as I understand.
Thanks

Hi,
I just notices that the tickness of the symbol into the label is less ticker than the one in the actual plot. Is there a way to change it? I cannot find a function to interact with it.
It seems like the import changed with the newer Qt versions: When embedding the library, the error from above is shown. Changing the import to #include <QtPrintSupport/QPrintPreviewWidget> worked for me, but I don't know if it's the best solution.
E.g. this change solved my issue: master...schlenger:qt_print_support_fix
Is there a way to know how good a LaTeX string was parsed? Maybe something like count of unknown symbols?
I want to draw LaTeX string to a pixmap as small as it can be. Is calling JKQTmathText::getSize(painter) the fatest way? (Does getSize() really use painter? I see it is not used in some nodes.)
Is JKQTmathText::draw() fast enough or I should cache the resulting pixmap?
Here is a demo of wiggle plot.
Can JKQtPlotter plot wiggle plot?

@jkriege2 do you have any ideas what the problem could be?
The example .ini style files have the tag [plot] https://github.com/jkriege2/JKQtPlotter/tree/master/lib/jkqtplotter/resources/styles
However, the JKQTPGetSystemDefaultStyle().loadSettings() methods' default tag is [plots], not [plot].
Hello, my friend.
Thanks for sharing this wonderful package.
I found a little buffer overflow which goes unnoticed on x86_64, but prevents the libs from running at least on ARM32 (Raspberry Pi).
If you run one of the examples with the 'valgrind' memory leak & buffer overflow error detection tool, you will find that "JKQTPImageTools::getDefaultLUTs()" gives a series of invalid writes of 4 bytes each.
Inspecting the code at "lib/jkqtcommon/jkqtpbasicimagetools.cpp", I believe that the lines like:
plut[JKQTPImageTools::LUTSIZE+1]=plut[JKQTPImageTools::LUTSIZE];
are not necessary (the last element is already set on the loop... and the element at JKQTPImageTools::LUTSIZE+1 seems to be out of bounds, since, for what I understood, you allocate an array with that same size).
On Raspberry Pi 1, loading the libraries fail with the message:
malloc(): corrupted top size
Aborted (core dumped)
... indicating that the overflow corrupted the heap. A hard to follow issue without valgrind.
After deleting these lines, everything seems to run as intended both on x86_64 (linux) and Raspberry Pi.
Hope this report helps you to inspect the issue.
I think there is a typo in jkqtplotter/CMakeLists.txt

the app works perfectly if I build it as an app.
If I create a shared lib with same code the code not gives result.
I changed TEMPLATE = app to TEMPLATE = lib and I compile the same code. But , the result comes an error.
code not give result as a qt shared lib
wifimouse app fully build with qt.
Source code of wifimouse server application
I install and run wifimouse app in my computer it works perfectly and all the options are works smoothly.
But, If I compile the same code as a shared lib in my computer it not works properly.
For example ; In wifimouse application there is an option for brightness controling
error comes like this. But , it works smoothly as a TEMPLATE = app.
Problem with qt in getting outputs.
I want to get the cpu usage , ram usage ,process list and app list with qt.
In Windows
I am getting ram usage from this code.
But app list , cpu usage and process outputs are not showed.
In linux
In linux the cpu usage output not showed.
In Mac
In mac the app list output not showed.
All the code works perfectly if I build it as an app.
Why this problem occured ?
Here is how I call JKQtPlotter:
QVector<double> fromCArray(const double *x, size_t len)
{
QVector<double> Y;
Y.reserve(len);
Y.resize(len);
std::memcpy(Y.data(), x, len * sizeof(double));
return Y;
}
void MainWindow::plot(const std::vector<double> &R,
const std::vector<double> &T,
const std::vector<double> &P)
{
size_t step = T.size()/10;
if (step == 0) step = 1;
JKQTPDatastore* ds=ui->plot->getDatastore();
ui->plot->clearGraphs(true);
for (size_t i=0; i < T.size()-1; i += step) {
QVector<double> X, Y;
X = QVector<double>::fromStdVector(R);
Y = fromCArray(&P[i*R.size()], R.size());
graph = new JKQTPXYLineGraph(ui->plot);
size_t columnX=ds->addCopiedColumn(X, "x");
size_t columnY=ds->addCopiedColumn(Y, "y");
graph->setXColumn(columnX);
graph->setYColumn(columnY);
graph->setSymbolType(JKQTPNoSymbol);
ui->plot->addGraph(graph);
}
ui->plot->getXAxis()->setLogAxis(true);
ui->plot->getYAxis()->setLogAxis(true);
ui->plot->getXAxis()->setAxisLabel("Density [g / cm$^3$]");
ui->plot->getYAxis()->setAxisLabel("Pressure [GPa]");
ui->plot->getXAxis()->setTickLabelFontSize(14);
ui->plot->getYAxis()->setTickLabelFontSize(14);
ui->plot->getXAxis()->setLabelFontSize(14);
ui->plot->getYAxis()->setLabelFontSize(14);
ui->plot->zoomToFit();
}And it takes about 0.5s to render. That seems really slow. @jkriege2 do you see any obvious inefficiency? I can see that the data is first copied from std::vector to QVector and then copied again (I assume) into JKQTPDatastore. Otherwise is this how JKQtPlotter should be used?
Hi, thank you for your great library which I enjoy using for the first time very much! I have some issues, I am not sure whether it is my lack of experience with the internals.
The most acute one is that JKQtPlotter is apparently scanning the whole system for all installed fonts and it takes lots of time. On my workstation (which has 64GB RAM, used mostly for disk cache, thus no actual disk access is entailed) this takes 10 seconds (full installatoin of TeXLive and several extra font packs); this is what strace is showing during those 10s:

Would it be possible to avoid this? I would be fine building without the math rendering library -- currently there is no option for that in cmake, could I help adding such option perhaps? Maybe you have some other pro tip :)
Thanks!
I've put in a PR for a fix to some problems with palette display - hope that's OK.

I got error during build the JKQTCommonSharedLib project with Debug(x64) configuration.
It seems like missing #include <stdexcept> header.
When I include stdexcept header in jkqtpdebuggingtools.h, build is success.

Hi, I wrote some code to disable default double-click action
plot = new JKQTPlotter(this);
plot->clearAllRegisteredMouseDoubleClickActions(); // this code should block default-click action, which is zoom-in.
plot->clearAllMouseWheelActions();
plot->clearAllMouseWheelActions();However, when program first start, I still can zoom-in by double-clicking the plotter (only once). I find this function may cause this problem:
for (JKQTPMouseDoubleClickActionsHashMapIterator it=plotterStyle.registeredMouseDoubleClickActions.begin(); it!=plotterStyle.registeredMouseDoubleClickActions.end(); ++it) {
if (it.key()==qMakePair<Qt::MouseButton, Qt::KeyboardModifiers>(button, modifiers)) {
return it;
}
}
return plotterStyle.registeredMouseDoubleClickActions.end();
// ....
auto itAction=findMatchingMouseDoubleClickAction(event->button(), event->modifiers());The return-value itAction is not equal to plotterStyle.registeredMouseDoubleClickActions.end() which is very strange.
Hello jkriege2. I'm a bit of a Qt/linux newbie, but now managing to find my way around. I'd love to use JKQTPlotter in several projects I have using the Qt UI system, but have not managed to follow your instructions.
My system:Qt Creator 6.0.1 Based on Qt 6.2.2 (GCC 10.3.1 20210422 (Red Hat 10.3.1-1), 64 bit) Built on Dec 15 2021 08:27:24
Using Qt 5.15.2 with GCC:
I have downloaded JKQTPlotter to /home/john/JKQTPlotter, and opened the file JKQTPlotter-BuildAllExamples.pro in QtCreator. On building it, I get a lot of errors about cannot find -ljkqtplotterlib_debug.
I don't see the built library files in the /lib or /qmake/staticlib folders.
I've tried various combinations of building the individual example projects (with & without building the lib), or building the qmake/staticlib/jkqtplotterlib/jkqtplotterlib.pro (again in QtCreator), with no more success.
Is this an issue with QtCreator 6 - I note a previous comment that this wasn't supported yet?
Or is there an obvious installation step I've missed out?
Thanks for any pointers - your package does look very much what I'm looking for.
John
With the latest master (cbd9882) I am now facing another problem:

As you can see, some Qt5 libraries and libJKQTPlotterSharedLib have the proper RPATH, but the libQt5Svg, libQt5PrintSupport, libJKQTMathTextSharedLib and libJKQTCommonSharedLib libraries do not.
Here is my CMakeLists.txt:

add_executable(my_application main.cpp mainform.cpp mainform.ui)
target_link_libraries(my_application JKQTPlotterSharedLib)So one must remove it by hand, e.g. (https://github.com/conda-forge/jkqtplotter-feedstock/blob/6cedd9980147f56054759cb2d6c30a8145c28d3a/recipe/build.sh#L12):

One should instead install it into $PREFIX/doc/JKQtPlotter.
Hello.
Please clarify in the comment of the JKQTMathText method:
/** \brief draw a representation to the <a href="http://doc.qt.io/qt-5/qpainter.html">QPainter</a> object at the specified position */
void draw(QPainter& painter, double x, double y, bool drawBoxes=false);What x and y should point to. Is it a top-left corner, center, or something else?
I tried to figure out and check in the code, but if to set x and y to 0, then there is no image drawn, whereas with:
void draw(QPainter& painter, unsigned int flags, QRectF rect, bool drawBoxes=false);with rect = QRectF( QPointF( 0, 0 ), size ) everything draws correctly.
Thanks.
Someone get it compile with Qt5.15 or Qt6?
I'm trying to understand if I can fix it on my own, but if someone already make it work would be great!
Hi,
Can we do this with JKQtPlotter ?
Tracking issue for:
$\leq$ and $\in$ using jkqtmathtext_test tool:
Hello. The subject...
Currently command \over is not implemented. For example:
x = {-b \pm \sqrt{b^2-4ac} \over 2a}

Hi,
first of all thanks for your amazing job into JKQtplotter. I would like to show the tooltip instead on the drag or the click action, on the mouse move event. Basically while hovering one datapoint. Can you address me how to achive this task?
Thanks!
The length of the x-axis name is positively related to the length of the bottom border of the chart. When the axis name becomes longer, the bottom border also changes, which looks very weird.
For example, you can try below code:
plotResid->getXAxis()->setAxisLabel("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx axis");
I want to show you my screenshots,but i didn't find the interface to add pictures.
I tried both gcc 9.1.0 and the default clang on macOS 10.11.6 and I got the same failure:

Now when JKQtPlotter is in Conda (https://github.com/conda-forge/jkqtplotter-feedstock) would you mind tagging a new release please? Currently the latest release, which is used by Conda, does not include #34.
