how to save graphs in scope

[Hymae]

What can I store the graph displayed in the component scope using the code into the form of a bitmap file? And what should I do?
If manually, this can be done by clicking on the save symbol on the toolbar on the right upper scope. And I have trouble when it will save the image measurement results in the component scope that is controlled using the code, so that I can make a system that can store the measurement results are automatically

Thanks
