wuttrain Posted April 29, 2008 Report Share Posted April 29, 2008 Hi, I noticed that repainting of the chart is really slow and freezes my form while it's repainting. I believe I have more than 200,000 points plotted to the chart. Here is what I did, when I queried the data, I put the query process and setting of the data source in a thread. The querying process seems to work, so threading is working but when loading the table to this (in the same thread): Me.Chart1.DataSource = [dataTable], it seems to freeze the screen, it then releases it when it's done. Is there a work around to this? My application has MDI windows and each window has charts that need to refresh every 5-10 minutes, and the refresh issue is going to kill my app. Thanks! wuttrain Quote Link to comment Share on other sites More sharing options...
