Can you set a data format (percentage) within DAX?

[Anonymous]

I'm currently using a parameter to switch the metric being displayed on a time series chart. However, one format is in dollars, while the other is in percent. The client really wants the percentages to be displayed in the XX.X% formatt. Is there any way I can achieve this within DAX code for the measure? Or in any other way really. 

Here is the code for the measure. 
Metric =
IF('Parameter'[Parameter Value]="Dollars",
    SUM('Table'[Dollars]),
    SUM('Table'[Percent]))

Please note that I am already using Field Parameters for this Metric, as there are three categories for the metric and the user needs to be able to choose which metrics they want displayed.

Metric =
IF (
'Parameter'[Parameter Value] = "Dollars",
SUM ( 'Table'[Dollars] ),
FORMAT ( SUM ( 'Table'[Percent] ), "Percent" )
)

Hi @Mahesh0016 , this doesn't seem to work. I only get a total percentage for all data points, it doesn't work on the line chart anymore.
