Hi, I am using UltraChart - PieChart. Initially, there should not be any data in the system, so there won't be any rows in the DataTable of the UltraChart. So the PieChart is displaying the following error: Pie3D Chart Error: You must include at least one row and one numeric column. I have read the User's manual. It also mentioned similar thing.
I have included one numeric column, but no rows.
Is there a way to display empty pie chart with no rows. Thanks, Nuha
Hi Nuha,
I used an empty bindingList instead of an empty table, which accounts for the different message, but basically you do need to supply at least one row that has at least one numeric column for the 3D Pie Chart.
If your table is not expected to contain at least one row with the required numeric value, you could use the InvalidDataReceived event and interrogate and modify the e.Text value. You could customize the text or set it to an empty string.

Thank you Marianne,
I am not getting the "Data not Available" message. Instead, I am getting the error message I described earlier written in red font and filling the ultrachart. The chart looks broken. So, is it a bug?
If you don’t provide a row with at least one numeric column you will get the Data Not Available message. But I provided a row of column(s) whose value(s) were 0 and that allow the form to generate without a chart and without any error.
Let me know if there is anything else I can help you with.
