Charts only support text values for X axis #101

Open tf13 opened 7 years ago

I've run into this attempting to use dates or numbers for the X axis. I can work around it by computing a new column that turns a number or date value into a string ... but should that be necessary?

The error message:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
