Is it possible to delete the default legend, and programmatically create a custom legend whose series can be preceeded by checkboxes, allowing a user to click to display / hide a particular series in the chart?
it is possible to custom-draw the legend using the FillSceneGraph event. however, if you want checkboxes in there, i recommend using some HTML outside the chart control for that. hiding a series will also require a postback to regenerate the chart image.
So in order to have a custom legend, you need to use the FillSceneEvent? Does this mean you need to add each item and colour box programatically? Or can you create an invisible chart layer with a series in and add that to the ChartLayers of the legend ?
Or is it a case of following example:

Invisible layers works fine. You don't have to add them to the chart layers so they won't be plotted.
Nice!
