virtual

It generates the image pattern from the given chart and the current element of dataset.

Parameters

chart	The chart informations that will be used.
dataset	The dataset that will be used.
width	An output parameter that will be filled with the width of generated image pattern.

Returns: The RGBA image that represents the chart.

Note: The caller will take the ownership of the returned pointer.
