I have a web page with two tabs and a couple scatter line charts on each tab. Switching between tabs take 10-20seconds with Silverlight v10.3 web chart. This is mostly due to charts re-painting. All data is already on a client. When charts has no data - I can switch between tabs in 1-2 seconds. The series are mapped using DataSource and DataMapping (200-500 datapoints). Populating DataPoints collection directly didn't help - I am still getting the same delay simply switching between tabs. Please advise. Thank you.
Thank you, Graham. The issue was that xamWebChart v.10.3 is loading very slow (> 15 seconds) for time series with over 2,000 data points. We can't switch to the 2011 version to see if there is a performance improvement. I had to redesign the web site to minimize charts re-drawing.
