Renko chart with VWAP

At this time it does not appear to be supported. I tried the following and it also does not show up on the chart:

plot data = vwap;

This tells me that Thinkorswim does not provide this data source to a chart that is set to display Renko bars.

Volume data appears to be available. So the problem seems to be that vwap data itself is not available. There is no workaround for this. You will need to contact Thinkorswim support to get more details our request that this be enabled (if it's even possible).

So the best solution for now is to run two charts side-by-side. One set to a normal time frame based chart with the VWAP displayed. Another set to the Renko bars.
