Slow chart with huge DataTable

Matthias posted over 15 years ago

Hi,

I bind a huge DataTable (about 250,000 datapoints, distributed to 3 series) on an Infragistics UltraChart. Everytime I went over the chart with the mouse cursor, the application hangs up for about 2 seconds. I have no UltraChart events added (which could slow down the UltraChart).

I tried to dissable the tooltips, but that didn't work. What else could I do?

With a DataTable that isn't as huge, everything works fine.

Thanks in advance,

Hello Matthias,

If you need tour chart to only visualize the data and don't correspond with the user you can set:

ultraChart1.Enabled = false;

otherwise when you hover over the chart a lot of things get loaded and with such a large data table some slowing down is almost inevitable.

Sincerely,
