I've come across an issue when changing a chart title before saving it 'toimage()'.
I have an excel template containing a number of charts. The chart titles reference a cell.
When that cell remains unchanged, the chart title is correct.
However if the cell contents are updated by an aspose 'putvalue', and then the chart image created by 'toimage()', the title is not updated.
This happens even if I run a chart(x).calculate().
Is this a bug, or a limitation, or is there a work-around?
