Hi,
Well, Aspose.Cells will work similar to MS Excel. You may try to create your desired chart manually in MS Excel and check the issue.
If you have different opinion, kindly do create your desired chart in MS Excel with your desired length (also find out if some of the labels are lost or not), and post the file here. We will check it soon.
Also to increase the chart's width and height, you may try:
chart.ChartObject.HeightCM = intNumber;
chart.ChartObject.WidthCM = intNumber;
Thank you.
