How to remove the first line of a "Table chart"

[#1]

Hello everyone,

So I have this straight table built with the chart editor. When I load the data the first row of the table does not have any values on any cells, only a dash  ( - ) on the corresponding the expression.

The data I load to the table doesn't have any empty line.

How can I prevent this line to show?

Is there any option to hide it?

In attachment there is a image to help understand the issue.

Thank you for the help

Best regards!

This is just a guess Vishal

From my understanding is how it seems to work.

And more, I export the table to excel with a macro, so the macro itself might have something also to do with this.

Regards!
