	pOptions	(params) additional options, which are optional. See the description below.
[out]	pPngData	(binary) image with the chart data. See Chart parameters structure.

Format of the pOptions parameter (if it is not empty):

            +--- (params)
                +---RPT_CHART_WIDTH = (paramInt) chart width, in pixels. Optional if RPT_CHART_HEIGHT is set.
                +---RPT_CHART_HEIGHT = (paramInt) chart height, in pixels. Optional if RPT_CHART_WIDTH is set.
