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,
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.
Marianne
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?
Hi,I am using UltraChart - PieChart. when data is null, the PieChart is displaying the following error:Pie3D Chart Error: You must include at least one row and one numeric column.
How to change it? just like empty or other message.
Thank a lot in advance.
Wondering is anything I can help you with.
Actually the message is correct; you do need to supply at least one row and one numeric column.
Here’s a link to the Overview of Chart Data Requirements.

If you want to modify the message when invalid data is received you can use the InvalidDataReceived event and change the e.Text.
Hi Marianne,
I have attached a file with how the pie chart looks when the number of rows is zero. I believe that the "EmptyChartText" shoud appear here in a nice way. Following is the source code I am using:
DataTable dt = new DataTable();
dt.Columns.Add("Status", typeof(System.String)); dt.Columns.Add("Frequency", typeof(System.Int32));
ultraChart1.DataSource = dt; ultraChart1.Data.DataBind();
This look like a bug to me. If you have a problem opening the attachment, please let me know.
Thanks,
Nuha
I’m just checking back if you have any follow-up questions.
Please let me know if there is anything I can help with further.
