Great chart components you have there. First I would like to upvote +1 the gantt chart type.
But I also have a question. How can you format the label on the chart? Like I put double values in a bar chart, and the label displayed contains a huge irrational number, like 9.13235215135 for each bar. I would like to format it to 9.13. Is there a ItemLabelGenerator where I get the numeric value passed and I return a String representation of the label to be displayed? Similar to the formatter, but more flexible?
Also other question, would it be possible to add a click listener? It could be fired when the user clicks a specific junction or bar or pie, etc. on the chart, passing some information in the event what was actually clicked. This could be used to provide further data to the user about the junction/point/pie/etc.
Hi, sorry for the belated response.
Currently, custom charts are not supported because that requires support for JS rendering methods to be injected from the server-side if we want it a fully flexible echo system to create any custom chart. Otherwise, I have to build case by case.
I know that the formatter needs improvements. Again, some sort of JS method injection technique from the server side can help here too.
On the event handling part, Christian Asnel Ngoulla started working on it and I will check with him about his plan.
