How to add currency symbol before values in chart?

[Thanvi]

Hi,

I have generated a graph to show monetary values as shown below. But I am not able to add currency symbol before the amount. 

The expression is just the column name "Amount", how can I modify this to get currency symbol.

Example: In graph, I have 1.2M and 1.55K. But I need $1.2M and $1.55K.
