This is much better as it does not affect QuickAFL. Cum() function forces ALL bars to be used all the time which is not

good when your formula is intended to be used in real-time intraday chart.

Thanks Fred,  That is what I was looking for.

This also works for me:

BarsVisible =  Status("LastVisibleBar") - Status("FirstVisibleBar");

BarDensity =  BarsVisible / Status("pxwidth");

Seede,

Thanks, I understand how to change the UI options. I was referring 
to an automatic determination of how crowded the bars were --not to 
change the spacing --but to modify some of my AFL parameters (like 
going to HL cloud instead of bar plots or switching to thin or thick 
bars automatically). I don't look at longer timeframes to see more 
of a chart, instead I show more bars on the chart because I want to 
stay in the same low timeframe to keep my indicators constant. When 
day trading, I don't want to be distracted with making a lot of 
manual changes to the display. If I can determine beforehand what I 
want, I can then program it into AFL.

In fact, figuring out how to change the number of bars displayed in 
the chart from AFL is next on my list of things to improve my setup.
