Hi,

Make sure you are properly updating the data. Please check the attached sample. It demonstrates how to update chart in real time. If it doesn't help you, please provide me more information.

Hi,

in one activity (or layout) I have smaller chart, which continuously draw the graph. When it is clicked, it will go to another activity (or layout) showing the bigger chart.

The problem is if I come back from the second activity, in the first activity, the smaller chart is not drawing anything . Please help me int this issue.

Thanks,

Sathish.
