Add a column to Easy Chart tagPens dataset


I have added a column to the Easy Chart tagPens to show some information, but it doesn’t work anymore when I drag a tag.
the error is as follows:
raceback (most recent call last):
File “event:mouseClicked”, line 9, in

  • File “”, line 106, in addPen*
    IndexError: Number of values (23) in row 1 doesn’t match number of columns (24) in dataset.

any help please.

Your customized addPen function has to be changed to supply that column, too.
