Welcome all,

I would like to extend pie chart and time line to add extra functionality.

What I would prefer not to do is (correct me if I am wrong):  
a) creating a completely new plugin with new pie chart or time line (pie charts and time lines are not available in UI framework)  
b) forking entire code base and overwrite source

What is the best approach to extend base visualizations ?

Thanks, Serg

There currently isn't really a great way to do this other than what you've suggested.

What were you hoping to accomplish in your extension?

What I would like to achieve is:

- pie chart: labels in legend should include value as well
- time line: multiple labels can be selected at once (with pressed ctrl), right now you can select only one label
