Is there a way to have volume bars for the chart of the $SPX on think or swim? if not, what platform charts the S&P500 with volume?

the attached photo shows a chart of S&P500 however their is no volume indicator on the bottom portion.

The simplest way to do it is to chart the /ES instead, yet trade the SPX. That is what I do.

Yes that is the way I do it as well...good info
