Detecting when user changes bar width

[anachronist]

In an indicator I'm writing, I would like to use the width that the user can change by pressing Alt-up and Alt-down. I see this in two places: ChartControl.BarWidth and Bars.BarsData.ChartStyle.BarWidth.

Is there a preference about which I should use? Either one seems to work but I don't know if there are disadvantages to one over the other.

I'm overriding Plot() to draw my indicator because I don't know of a better way to plot a bar chart using my own calculated values for open, high, low, close. If there is a better/cleaner way, please tell me.

Hello,

Thanks for the forum post.

Unfortunately since there is no documentation on this you are operating out in unsupported territory here.

I would suspect that both methods should do the trick for you however since its unsupported theirs not much more information I can provide other then that.

Let me know if I can be of further assistance.

FYI - I like to have my candles a constant width - it helps me with pattern recognition. So the bars.barsdata method works better than ChartControl.BarWidth - I don't know why.
However be aware that if you zoom in and zoom out the autoscaling is effectively overriden so this wouldn't be to everyone's taste.

am not a programmer, but from your post here, am wondering if you found a way to adjust bar width by adding an indicator to a chart. would like to compress (reduce) bar width and spacing on some of my tick charts in order to view more historical data and recent history within a normal window. the normal horizontal spacing tools do not provide enough for my needs. can you point me to any solutions on this subject...? thxs much Will

Hello valhallafutures,

To change the bar spacing or width:
ChartControl.BarWidth = 10;
ChartControl.BarSpace = 10;
