fair-acc/chart-qt

ChartQt is a charting library written in C++ focusing on performance. It uses the Qt libraries but has a dedicated rendering system running on top of QtQuick which gives it great performance and a wide platform support, being able to use any of the 3D rendering APIs OpenGL, Vulkan, Direct3D and Metal. Still in early development.

chart-qt's Issues

[moved to other project] [8pt] A basic 3D plot example for Implot (mountain range or 3D surface plot) for technology evaluation

[moved to other project] [3pt] Export of all or selected DataSets and views to a file, clipboard and printer through conversion to PNG

[moved to other project] [2pt] Correlation plot - plot the values of one signal against the values from another signal

[moved to other project] [2pt] Implement the basic arithmetic operations for signals - SignalA +/-/*/... SignalB

[moved to other project] [3pt] Show additional information (range and other meta-data) on a legend in the hover tooltip

[moved to other project] [5pt] Getting to know Implot

[moved to other project] [5pt] Zoom and panning should work with mouse and touch where available

[moved to other project] [5pt] Implement story: User selects a custom list of signals to add them to the collection, which is then added as a view to the UI

[moved to other project] [2pt] Live switching between different color schemes

[moved to other project] [5pt] User can modify, regroup, split signal into sets or single views and perform simple grid/box layout adjustments

Prototoype finalization

Open issues going towards open sourcing this as an end user library:

• move code from chartItem for increased modularity
  • axis code decided to keep this in the chartItem class for now
  • zooming code (keep zoom state in ChartItem and only move UI aspects to separate class?)
• chart layouting
  • allow dynamic axis width (-> 2 passes, first determine axis positions from label widths, then perform actual rendering)
  • allow multiple axes on same side (currently rendered on top of each other)
  • MultiChart layout container to align multiple charts
• Axis
  • clip axes correctly
  • hide labels based on maximum label width instead of hiding individual labels could not reproduce anymore
• rhi-Abstraction and reusable default shaders -> users should not have to interact with rhi/shaders for implementing simple custom renderers
• expertUI
  • extract expertUI/sample into cmake subproject
  • show values from the rest interface in the chart not implemented, because it would have needed changes in the rest service part
• QML
  • investigate why chart does not work inside of layout containers
• investigate wasm buffer bug

[moved to other project] [8pt] Inspect and modify flow-graph and block/parameter definitions in the FEC (GNU Radio and RxCPP) and in the UI (RxCPP)

[moved to other project] [2pt] Feature and parameter extraction (minimum, maximum, location of maximum, pulse width...)

[moved to other project] [8pt] UX design analysis - plug-in and component definitions required for the digitizer UI, etc.

[moved to other project] [5pt] Simple configurable layout of views - grid layout, horizontal and vertical box layout, spanning grid view

[moved to other project] [3pt] Demo UI using Implot

[moved to other project] [3pt] Investigate Implot community and health

[moved to other project] [5pt] Storing, clearing and reloading the flow-graph and the UI configuration

[moved to other project] [1pt] Export DataSets on each subscription update

[moved to other project] [2pt] Support for scalar values to be plotted as history (i.e. actual value versus wall-clock time)

[moved to other project] [2pt] Implement FFT

[moved to other project] [5pt] Implement story: User adds post-processing based on one or more signals, thus creating a new signal source

[moved to other project] [3pt] UI widget to directly access and modify digitizer parameters such as (vertical) input range, offset, etc.

[moved to other project] [2pt] Layout or view detaching to a separate window

[moved to other project] [5pt] FEC and UI debugging tools: log-viewer, display metrics
