Thread: Problem with the chart's key

Hi!
I have a problem with the chart's key. When the head of the column is text it's written in the key, but when it's a number it's introduced in the chart, and the key looks like:

Series1
Series2
Series3
And I also changed the data type to Text.

Here I have an image, so you can understand what I said.

Use the Source Data dialog to alter the data and name ranges.

or change the values to and then create the chart
