What object do I have to declare to gain access to BarsVisible? I thought it would be Price History but not so.

Bars Visible? As in how many bars you can see on the chart?

I need to compute the average volume over the visible bars as the first step to computing a volume adjusted moving average. I thought BarsVisible would help me do that but then I discovered that IsFirstBar CurrentDate was in June of 2002 with less than 5 months visible.
How would you write that code?

However resizing the chart area does not refresh the value plotted until the symbol is changed.

Adding this to code will refresh your plot when you change the number of bars visible or scroll the chart.
'#RECALC_ON_ZOOM_SCROLL
See page 46 of the RealCode Reference.

Note this permits displaying the number of bars visible on the toolbar by adding a data display item and editing the block diagram of said data display item.
Add Data Display.3
Edit Data Display.3's block diagram
