User (Legacy) Posted June 4, 2002 Author Report Share Posted June 4, 2002 I upgraded to the latest version of ChartFX Lite and my program no longer compiles. The compilation error is taking place on a OpenData() call. The call no longer accepts COD.ResetMinMax as a value. Why not? Removing this value allows the program to compile, but charts draw very slowly. This enumeration just seems to have vanished somehow. Where is it?

User (Legacy) Posted June 4, 2002 Author Report Share Posted June 4, 2002 I'm not sure if the removal of COD.ResetMinMax is what is causing the charts to draw so slowly. The slowness is occurring when I set the legend for the X axis of my line chart. This loop used to run really fast, but now is insanely slow using the latest version: for(int xIndex=0;xIndex<PerformanceData.ChartPoints.Length;xIndex++){ CumPLChart.Legend[xIndex]=PerformanceData.ChartPoints[xIndex].Date.ToString( "MM-dd-yy"); } Again, the code works but it's just too slow to be used in a real application. Version 6.0.768.32264 worked fine. Version 6.0.865.33771 has the problem. David Link to comment Share on other sites More sharing options...

User (Legacy) Posted June 4, 2002 Author Report Share Posted June 4, 2002 During this loop, the chart seems to be constantly redrawing itself... I think I need a way to tell the chart to stop drawing itself during this loop... Link to comment Share on other sites More sharing options...

Software FX Posted June 5, 2002 Report Share Posted June 5, 2002 1) COD.MinMax is no longer necessary and it is not consistent due to some new API. You can reset the desired axes before calling OpenData by calling axis.ResetScale. 2) I don't see how the chart can be drawn while your code is in a loop as there is only one thread, please send us an example of the problem you are experiencing. -- FP Software FX, Inc.

The reason I thought that the chart was redrawing itself was because it would continually flicker during the loop. I worked with Justin and Rob on the problem, and eventually a solution was found. As it turns out, it has nothing to do with COD.ResetMinMax. The problem applies to people who are upgrading their projects from CFXLite to the full version. These people need to: - Uninstall CFXLite - Delete the program files directory and \common files\install fx directory - Reinstall as 'administrator' - For WinForms apps, all of the references need to be changed, and ChartFX.Borders.dll must be referenced, regardless of whether or not custom borders are being used. 'using' directives must be changed, etc.. - Existing charts must be deleted from all pre-existing forms and re-added. If each step is not performed exactly right, the program will still compile but bizzare performance problems will occur (as described in my previous message), and the charts will throw NullArgumentExceptions during repainting in design view if their properties are examined or modified. I sent Rob detailed screen shots and a followup email -- but I think I have everything working now. David Link to comment Share on other sites More sharing options...
