barindex starts counting the bars in the chart from zero. 1st bar is 0.
The area below the chart that shows the cursor position is for the bar
number as cum(1) would calculate it.
barindex is from 0 to (Barcount-1)
chart values box is from 1 to barcount
You can do a simple exploration
filter=1;
addcolumn(barindex(),"barindex",1);
or add it to your chart title
title = blahblahbalh +" barindex = "+ barindex();
or even show it in the Interpretation window for a chart, just add
this anywhere in the AFL
"barindex = "+barindex();
These techniques can be used for any variable or array.
Of course the other radical and innovative method would be to use the
help files, and type barindex into the search in there
