Which is the best way for real-time charts?

[banduk]

Hey people,

I'm using gxt for a research project and I need it to generate real-time linecharts for me.
But the problem is that I'm receiving data each 2 seconds and I have more than 1 line in each chart.

For now I'm using a List of line charts and each value received I put in the right line and refresh the chart.

It's running really slowly. So, I just want to know which is the best way to keep these charts up to date. Is it possible without lagging?

Thanks,
Banduk

In the forthcoming GXT 3 we have built Line charts for just such a use case. http://sencha.com/examples-dev/#ExamplePlace:livechart
