[swtchart-dev] Buffering Chart Data via a Bitmap

[Yash Bharatiya <yashsoc@xxxxxxxxx>]

Hi,

Currently SWTChart redraws everytime the user zooms in or out causing performance issues,

I looked at the issue-https://github.com/eclipse/swtchart/issues/85

Does that mean the chart will be converted into a graphic image and then scaled or resized whenever zoomed in or out instead of redrawing?

The chart can be converted into an image using ImageSupplier class,

ImageSupplier imageSupplier = new ImageSupplier();
ImageData imageData = imageSupplier.getImageData(scrollableChart.getBaseChart());

Image image=new Image(display,imageData);

Thanks,

Yash
