Chart issues after changing display of a number

[Oblivion_05]

Hi, I've changed my display of numbers to in terms of "k", e.g. 54101 to 54.1k . I have done this with four columns. Now when I'm trying to draw a row series chart with these new displays it's not showing anything. Can someone please help me with this?

How did you change the display of numbers? Screenshots of relevant configuration would be helpful.

I changed the display using the following expression:
Concatenate(Display(Round([Column])/100)/10.0,"k"). 
Although I got the reason as when we apply concatenate, we change the data type from numerical to string which was the reason I couldn't draw the curve.

Thanks for replying!

That expression is invalid: there is no DISPLAY() function.

Sorry that's a typo from my end. I wanted to write Decimal() instead of Display

Numbers must be numbers. Adding the "k" at the end makes it text.

You could try to have the column name itself to display the K notation. As the following example shows.
