Chart with multiple line graphs displays slowly

[Chuck Lynch]

I have a chart based of the Dashboard example.  It has a RadChart with three sets of ChartTilte, ChartArea and ChartLegends.  But in my case all three chart areas contain graphs with SplineSeriesDefinitions.  The layout is two graph in the first row and one graph in the second row.  The graph in the second row span the width of the control.  The graph in the upper left has three series with 15 point in each series.  The graph in the upper right has six series with either 4, 5, or 6 points in each series.  The lower graph also has six series with six points in each series.

I can not get this control to animate the graphs.  It seams to hang while building the graphs and then suddenly refresh after eight or nine seconds.  The data fetch is not a factor, since I have buttons on top to change views of the data that does not fetch any data just rebuilds the graphs with different properties in my data set.  The slow refresh is really noticeable then.

Is there anything I can do to either get the animation working or be notified when the control is finished building the graphs?

Hi Chuck Lynch,

Hm.. that's really odd. The chart shouldn't be struggling with this much data at all. Did turning off the animations in all charts help? Can you provide some source code to see how you supply the charts with data? We would like to help, but without more info we can't do much more than guess :(.

P.S. We have identified a memory leak in the control released with SP1 release. Have you tried using a recent latest internal build? They generally have better performance than the official one.

Kind regards,
