Draw on CartesianDataCanvas item that larger than the chart

Question

Hi Community, I want to draw on a Flex AreaChart. This AreaChart has an AnnotationElement that is an CartesianDataCanvas. When I draw some items on this CartesianDataCanvas, the chart looks good when the item fits inside the chart. But when I draw an item that is bigger than the chart, the chart automatically resize and try to fit my item inside the chart. I dont want my chart to resize automatically like that, but rather not showing the item part lay outside the chart. What should I do?

Thank you a lot, Henry

Answer 1

what about scaling it manually?

before you draw it on the canvas, determine the sizes of AreaChart including width/percentWidth and same for height, and scale your graphics to fit the canvas/AreaChart.

If you want to do it right, research this canvas to next properties:

explicitMaxWidth and postLayoutTransformOffsets and this too setLayoutBoundsPosition () from documentation about AreaChart & CartesianDataCanvas

And let us know :)
