Live plotting of graph in qml

[reshmi]

Hi

I need to create a live graph plotting application.The cpp part of the project is continuously sending the data.these data has to plotted dynamically in run time such that the graph will be moving.
Same as what we see in a ECG.

How can I implement this in qml.

What is the appropriate way to do that.

Regards
Reshmi.

If you have time, you can refer to qwt, and then develop UI components like qwt in QML.

see CPU usage

If you have budget, Qt chart should help you.

The stocqt demo in the qtdeclarative module draws a graph of stock prices.
