I am using a Spline chart with a theme applied. If a control in the page causes a postback, the lines in my chart change color, resulting in some lines getting almost invisible.
I have created a small demo project demonstrating the problem: http://imar.spaanjaars.com/Downloads/Other/TelerikChartIssue.zip
If you open Default.aspx in the browser, there's a green and a red line. If you choose an item from the DropDownList, the page posts back and the chart changes color.
What do I need to do to fix this?
Also, what do I need to do to change the color of the lines? I changed about a million Appearance properties, but to no avail. Do I / can I change the skin somehow?
