Method Details

getReportDpi

public int getReportDpi()

Description copied from interface: ChartContext

Returns the resolution of the report the chart belongs to. Charts lay themselves out in points, so anything derived from the pixel dimensions of the chart element has to be converted before it can be used as a chart coordinate.
