Taking more time to display the chart


Recommended Posts



I'm trying to create a line chart with 5000 data points. Assigning data to the chart control is taking 10 sec only. But while refreshing & displaying the chart in the web browser it is taking more time.

For assigning data to the chart control i tried 2 ways. One is Chart.Data & other is Chart.DataSourceSettings.DataSource

How can i reduce this time.

Am i missing anything here.

If the time is being spent painting the chart, the way you pass the data becomes irrelevant. What you need to look at is the chart settings. Default settings are not designed for charts with such a large number of points. Things to look at:

1) Marker Shape: The default marker shape (marble) is very slow.

2) 2D/3D: 3D Charts are much slower than 2D charts

3) Gradients

4) Per-Point attributes

5) Gallery Type
