Indicator bars with different starting points?

[Zapzap]

Hi,

Is it possible to have an indicator drawing vertical lines, but not from 0 to specific value, but from specific value to specific value?
That is showing two variable values on one bar, not only one... Something DrawLine can do, but for the whole chart, for every pricebar.

Thanks

Zapzap,

Have you tried just using DrawLine() and just using the same startBarsAgo and endBarsAgo values?

[Zapzap]

Yes, I have tried, but I haven't managed to draw the indicator lines for all the previous pricebars, only for the pricebars being drawn after attaching the indicator.
So Plot can go back in time (but can't do the job), DrawLine cannot (?) go back in time(but can do the job). Or maybe DrawLine can go back too, but I don't know how.

Zapzap,

Please ensure you are using unique ID names for each of your draw objects.

[Zapzap]

Yes, I do.

But how can I go back in time, and draw the lines for all pricebars on the chart without Plot?
By using a for cycle?

Zapzap,

Not following you. As you load up an indicator onto a chart it will already process each and every bar. It will go through and draw a line on each of your bars.

[Zapzap]

Hm, then it should work...
I thought I need to use Plot dataseries to draw for all visible bars, not only for the new ones...

Well, I keep on trying then.

Zapzap,

Plots do not influence DrawLine() objects. If in OnBarUpdate() you only had one line of code for the DrawLine() it will draw on every single bar it processes.
