volume profile

I have a chart with the definition below. It's an IsVolumeCandles RTX chart with Volume Profile (Background) and Color (Delta).
I'd like to export the volume profile and delta data for analysis.

When I Export --> All Chart Data, I get a file with header
Symbol, Date, RTX, RTX, TNOTE, NOTES, Open, High, Low, Close, Volume
.
But this exported file doesn't contain any of the volume-at-price or delta-at-price data that are reflected in the chart.

Can anyone point me in the right direction to export the volume and delta at each price from this chart?

So when volume profile histograms are displayed for each intraday bar (let's say 30-min bars) , the maximum width of the histogram is the same for each 30-min bar. All the histograms are the same width regardless of the amount of volume in each 30-min period. So I can't tell from the histograms if the volume was large or small during that period. So I wonder if there's a way to scale the volume histograms across the entire day so that I can compare the relative volume profile sizes for each 30-min bar?
