Implement functionalities from Linux Chart Tools into Circular Charts

himanshu-balasamanta commented 4 years ago

This includes

Ability to plot multiple pie charts on a single plot area
Adding a title to each pie chart
Implement the same API as used in Linux Tools

himanshu-balasamanta commented 4 years ago

A list of the APIs to be implemented will be updated here soon..

himanshu-balasamanta commented 4 years ago

API to return the node where an event occured. getSliceIndexFromPosition(int pieIndex, int x, int y)
An API to get the percentage of the node w.r.t. the rootpointer/rootNode - getSlicePercent(int pieIndex, int sliceIndex)
Add NodeSettings in addition to just the circular chart settings
Option to redraw the chart on clicking of merely Highlight the node.

All of these can be implemented in the current swtchart pie charts.

All functionalities are added, However The Legend needs improvement, Currently, one can only create multiple single level pie charts. Need to add functionalities to create doughnut charts, and multiLayered Pie and Doughnut charts.

Allow an option in parallel Pie Charts to redraw on click. All of them should redraw in sync.

himanshu-balasamanta commented 4 years ago

Implemented redrawing parallel pieCharts on sync, but legend is not in sync, as the legend is separate from the basechart. Legend gets redrawn only when the entire composite is redrawn (resized). @eselmeister , we need to add a listener to ParallelPieCharts class that redraws the legend when any of the charts register a mouse down event. What do you think, how should this be done?

Need to make a wiki for pie charts too. And then update the mailing list, add examples indicating the API usage.

Hi Himanshu,

I assume, that we need some kind of observer pattern here. Let's have a look if Java or SWT supports the pattern out-of-the-box.

Best, Philip
