The valueAxis.Title.Text value I'm using (e.g., "Number of Items") is being cut-off on the chart. I've tried a variety of font sizes, auto scaling of the font, but nothing seems to work. Is there a method for ensuring that the title is fully displayed?
Well, I think you may try to minimize the font value axis title's font size if it is a big one using... chart.ValueAxis.Title.TextFont.Size property .... and Aspose.Cells always try to auto-scale the values axis title. The values axis title frame area also depends upon the height and width of the chart area.
