I created a dojo
https://dojo.telerik.com/@rareddy/exaRi
Top chart is taken from the Telerik demo, bottom chart is mine. Click the "redraw" button at the top, and you'll notice my chart does not redraw and ends up being blank.
The only difference, and you can test this by copying the series, is that the "field", "datafield", and "colorfield" are specified in the datasource in mychart.
Am I doing something wrong or is this a bug?
