Hi Prince,
Thank you using Syncfusion products.
Chart title is limited to number of lines and depends
on the font size applied. For the default font size, you can able to view up to
six lines in chart title. Reducing the font size can help you in achieving
this. This is the default behavior of MS Excel and XlsIO does the same.
Please let us know if you need any clarification.
Regards,
Prakash Kumar
