d3 based visualization library - svg & canvas

giotto's Issues

Tooltip formatting

Add tooltip formatting based on axis formatting

angular Tests

Svg points keep mousemove

The mousemove event on svg symbols is not stable

lint tests

svg - canvas switch on the context-menu

Add svg-canvas switch on the context menu (right click menu)

Fix zoom plugin

The zoom plugin is not working.
It needs refactoring to deal with multiple groups on a paper.

Allow to change background color

The background color to be editable on the context menu.
We may need a color picker widget for this.

Add support for themes

Legend drag & drop

Add functionality to drag and drop chart legends

Pie labels for Canvas

Pie chart labels are not available for canvas groups

Barchart on multiple series

Currently, barcharts work only on one serie.
Multiple series barcharts should handle

• stacked bars
• adjacent bars

Better margin option

Currently margins are specified by the option margin, for example

margin: {left: 10, right: 10, top: 20, bottom: 20}

We want to be able to set them as a percentage too

margin: {left: '5%', right: '5%', top: '6%', bottom: '6%'}

Useful for creating nested charts and visualizations which resize gracefully

Tooltip does not collapase on context menu

When opening the context menu (right click) the tooltip should not display when hovering the menu.

Canvas transitions

Currently, transitions are only supported on svg elements (groups).
To have transitions in canvas a suitable implementation is required.
The transition api should be implemented at group level or at drawing level?

Zoom Broken on canvas

for details

downloadPNG

I've created the downloadPNG for an svg visualization using the cloudconvert API but it is not working. The problem is how to upload the file.

Add slider

Slider is a great for UI of inputs in a range, like percentages and so forth.
There is a slider file in utils.js which is the target implementation

sliders styling

At the moment sliders have no styling.
We need to come up with a design on how to apply styles.
Css to be included in javascript as usual.

Brush plugin is broken

The brush plugin is broken for both canvas and svg

Unify the point symbol API

Tooltip values to update when data change

Tooltip legend needs to update the values when the underlying data change.
The transitions exmple highlights the issue.

Rewrite triangligy visualization as plugin

Trianglify visualization create a canvas or svg element.
We need to rewrite the trianglify visualization as a plugin which enhance the fill plugin. In this way we can use the trianglify libarry to set the background of charts.

Bubble charts using the force and pack layout

Add bubble charts using force or pack layouts.
bubble charts can be an alternative to bar and pie charts, therefore displaying relationship between an ordinal and quantitative scale.

Bug on canvas brush

The extent disappears on mouse-over

Missing gradient background in example

The background in the gradients example is not showing!

Remove option processors

The options.processors object is a hack and should be replaced by these four simple plugins:

• margin
• colors
• font
• transition

/examples/europedebt example broken

The animation is broken, probably due to the many changes.

Bar Chart active elements on canvas are always black on safari

Horizontal bar chart example

Fix hidden text in parents elements of sunBurst

When the text of a parent elements is longer than the arc radial length, the text is hidden by the child path element. Maybe text and path should live in a separate g to fix the problem

g -sunburst
    g - path
    g - text

example testing

Using casperjs?
Replaces quantmind/d3-view#1

No tooltip for pie charts on canvas

Remove svg/canvas dropdown

Svg or canvas can be selected on the context menu. No need of external drop-down choice.

Handle multiple series in the same group

Currently each serie is assigned a new giotto group.
This works fine in most cases, however, when dealing with later multivariate time-series this is no longer always a good solution

Broken test suite

The test suite is failing. It needs fixing and a proper mock framework put in place.

opacity should work when colors don't set one in background plugin

Check the radial example in
