    I am able to draw chart on canvas .Now, I want to rotate chart (canvas) with sync of orientation sensor.
    Note – I am able to rotate imagesprit with sync of orientation sensor data but not able to create chart.

      That is an interesting idea – but I do not think there is a way to rotate the Canvas area other than to use sprites.

      I suppose, and this is thinking about this as I go, it is possible to save the Canvas drawing area to an image file on your device. Then you could also load that image file to be the image used by the image sprite. Then rotate the image sprite using the Heading and Rotate properties.

      I think this would work, but I do not know if it would be fast enough or smooth enough – it means drawing on the Canvas, saving to the device, then loading into the image sprite.

      This is just an idea, but who knows?
