Want to show 0% to 100% on Y-Axis of the report, not able to impliment % sysmbol on Y-Axis

Have Created one Bar report, where I have X-Axis and Y-Axis where I want to show % symbol on Y-Axis but now only getting like 0 to 100.

The bar shows numbers, not percentages. 
The only thing you could do is to update the title of the Y-axis in the style tab of the report. Then it will say 'percentage', but the numbers will just be the numbers.
