Changing z order programatically?
Is there some way to change the z-order of a data series programmatically in NT7? I would like to create an indicator that at the close of every bar, automatically brings the price bars to the top of the z-order, on top of everything else that is painted on the chart. Is there some way to do this in NinjaScript by any chance?Tags: None

Thanks - incidentally, this unsupported code where we can set ZOrder = -1.... can we also set it to something else to put it always on top of all the other indicators? What would happen if we put a really big number there, like ZOrder = 100? Would it work and just make the indicator topmost, or would it crash because it was trying to set it to a value that was greater than the number of plots on the chart?

Bertrand,
I was just pointed to this thread from Ryan. Handy workaround.
I've started to add the ZOrder = -1 to ALL of my indicators, so that price will always be on top. Could there be any issues in doing this? That is having all ZOrder values equal to -1? What exactly does setting ZOrder to -1 do? Does it just place the indicator "outside" of the ZOrder processing? What if I programmatically set all my ZOrders to like 999? Would there be an issue with multiple indicators having the same ZOrder?
Thanks.

Hopefully you're not talking about programming script.
I have a problem with an indicator by PrTester, "Keltner Channel with Color". The first chart I added the Keltner on a 100 Range and it's perfect. However, when I applied it to a 40 Range and 60 Range, the Keltner is ON the bars, not behind the bars like on the 100 Range.
I emailed PrTester about this and he directed me to this thread. ???
I don't want changes to my EMAs as I like them on top of the bars.

Hi Sharon,
I see that Bertrand got back to you before I could. Anyway, to reiterate what Bertrand said, I placed the code (yes it was NinjaScript) within the Initialize() section of the indicators. I am a programmer, so this was no big deal for me.
I want to point out though, that I am no longer setting the z-orders to -1 in my indicators, as it caused some "odd" behavior. So, I abandoned it. However, with Bertrands response, I will try setting the z-order for each indicator on my charts manual, and see how that works out.

Strange. I added the ZOrder = -1, and it works when the indicator is applied the first time, but refuses to work the second time. I had removed the Keltner with colors from a 150Range chart, applied the indicator after I had gone in and made the correction and it worked. Then to test it, I removed the indicator, applied, and closed. Opened and put the indicator back on and it wouldn't work.
Here's the correction I made using your example:
///<summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
///</summary>
protectedoverridevoid Initialize()
{
Add(new Plot(Color.Blue, "Upper"));
Add(new Plot(Color.Blue, "Lower"));
Add(new Plot(Color.DarkGray, "Midline"));
diff = new DataSeries(this);
Overlay = true;
ZOrder = -1;
PriceTypeSupported = false;
}
So what's wrong that it's not consistent? Maybe because the original one that worked on my 100Range chart is still the original? I didn't mess with that one at all since it was correct from the beginning.
