Bar Chart Column Name/Display Text

[GabrielRullan]

I have a table where I record the amount of money each customer pays every month for the past 12 months. 

The column names are basically:
"Current_Month",
"Current_Month-1",
"Current_Month-2",
..."Current_Month-11"

I then have a function for calculating the Display value for each month depending on the current month. (I.E. If current month is July, then [Current_Month-1] will display "June".)

This works in the form view, but when viewing a bar chart the columns show their names instead of their display values.

(The image below is mostly in spanish but the point is the same.)

Is there a way to change the text displayed at the bottom of each column?

I think you have to choose the correct column in the chart view.
