I'm having a problem right now where I'm creating a chart via koolreports. I want to do some stuff with the chart, like getting how many slices a pie chart has or what the value is (in js preferably), but I have no idea how to get these properties or how to use my canvas that's rendered in javascript instead of php, since as far as I know theres no way to get or edit these properties with php or koolreport. Is there any way this is possible? For example, how would I say "get slice 2 of this pie chart" or "get bar 1 of this bar chart"; stuff like that. Thanks in advance.

UPDATE: Getting a little closer. I've done $data = $this->dataStore('name'); which does successfully store my chart. I'm just now trying to figure out how to dynamically access the contents of the chart.

I've figured out that I need to somehow get the canvas to javascript, but the canvas is a random name each time. Is there any way to change the id of the canvas that koolreport renders, or any way to get javascript to grab one that is rendered?
