Hi all,
I'm using RadHtmlChart (LINE) for displaying data in 3 series.
X-Axis is the timestamp, Y-Axis the value.
The datasource is a dataTable containing all the data for the chart. One column for the timestamp, 3 colonnes for the 3 series values.
The user can choose the datetime range for the values, and depending of the selection, the loading of the chart can be very long.
For example, for loading 800 rows (ie. 2400 points in the chart), it take about 5 sec for rendering the chart. And the user should be able to load 100x more values !
It RadHtmlChart a good component for large amount of data ? What are solutions for optimizing the chart load ? I've tested the query time on the SQL Server, and it's not a problem, It take about 0.5sec for 17600 rows.
Thanks for your help,
Steve Roh
