Z-Order for Drawings

[DanDaMan]

Hi,

I am drawing a Fib-Extension on the chart, and have the different levels set with varying degrees of opacity. When I draw, the bars on the chart end up 'behind' the drawing, and you can see that the shaded fib levels are on-top of each bar. I would like to have the drawing and shading behind the bars, and I manually do this each time by Shift+Middle Mouse Scrolling on the Fib drawing until it is at the highest level and behind the bars.

Is there some way to set the default level for a drawing tool, so I do not have to do this over and over all the time? I do this a hundred times a day.

Hello DanDaMan,

Thank you for your post.

Unfortunately no, it's not currently possible to set a default Z-order for chart objects. However, I have added a vote for you to a current feature request to allow the Z-order of drawing objects to be set as a default. This request is being tracked under the number SFT-2833.

As with all feature requests, interest is tracked before implementation is considered, so we cannot offer an ETA or promise of fulfillment. If implemented, it will be noted in the Release Notes page of the Help Guide.

Please let us know if we may be of further assistance to you.

Hello Kate,
kindly add my vote (if not already)
I don’t know the extent of the Feature Request, but some further thoughts in similar vein for consideration - I use OHLC indicators. If, say, price Opens at what is/becomes LOD z-order of which is highest level & thus visible is not ‘configurable’ as far as I can see. Just ponderings/food for thought from experience along the way.

thanks

Hello brucerobinson,

Kate had added your vote.

Something you may wish to try for drawing drawn from NinjaScript would be to set the ZOrderType property of your drawing object after it is made to control the order it would be drawn. This may not give direct control, but may provide enough functionality to satisfy your ordering requirement. Please note that bars will not have individual ZOrders, each bar in ChartBars would have the same ZOrder.

if (CurrentBar < 5)
    return;
FibonacciExtensions myFibExt = Draw.FibonacciExtensions(this, "tag1", true, 4, Low[4], 3, High[3], 1, Low[1]);
//myFibExt.ZOrderType = DrawingToolZOrder.AlwaysDrawnFirst;
//myFibExt.ZOrderType = DrawingToolZOrder.AlwaysDrawnLast;

More information on ZOrders can be found here - https://ninjatrader.com/support/help...art_zorder.htm

For manually drawn tools, a copy of the Drawing Tool can be made that sets the ZOrderType in State.SetDefaults.

Hi _Jim, I have a question regarding manual drawing tools:

I have a special "Sidi Rectangle" and would like to be able to set the ZOrder. Unfortunately, this here does not work!

[EditorBrowsable(EditorBrowsableState.Always)]
public class SidiRectangle : Rectangle
{[INDENT]protected override void OnStateChange()[/INDENT][INDENT]{[/INDENT][INDENT=2]base.OnStateChange();[/INDENT][INDENT=2]if (State == State.SetDefaults)[/INDENT][INDENT=2]{[/INDENT][INDENT=3]Name = "Sidi " + Custom.Resource.NinjaScriptDrawingToolRectangle;[/INDENT][INDENT=3]ShapeType = ChartShapeType.Rectangle;[/INDENT][INDENT=3]// always draw this first
ZOrderType = DrawingToolZOrder.AlwaysDrawnFirst;[/INDENT][INDENT=2]}[/INDENT][INDENT]}[/INDENT]
 
 }

...and this one only works after setting another drawing tool (probably when the chart is renewed?):

[EditorBrowsable(EditorBrowsableState.Always)]
public class SidiRectangle : Rectangle
{[INDENT]protected override void OnStateChange()[/INDENT][INDENT]{[/INDENT][INDENT=2]base.OnStateChange();[/INDENT][INDENT=2]if (State == State.SetDefaults)[/INDENT][INDENT=2]{[/INDENT][INDENT=3]Name = "Sidi " + Custom.Resource.NinjaScriptDrawingToolRectangle;[/INDENT][INDENT=3]ShapeType = ChartShapeType.Rectangle;[/INDENT][INDENT=3]ZOrder = -1;[/INDENT][INDENT=2]}[/INDENT][INDENT]}


public override void OnRender(ChartControl chartControl, ChartScale chartScale)
{[/INDENT][INDENT=2]base.OnRender(chartControl, chartScale);[/INDENT][INDENT=2]// Print the currently assigned ZOrder index for this NinjaScript object[/INDENT][INDENT=2]Print("Current ZOrder level is: " + ZOrder);[/INDENT][INDENT=2]ZOrder = -1;[/INDENT][INDENT]}[/INDENT]
 
 }

Since the object has not yet been completed, the ZOrder will not be adjusted. How can I set the ZOrder here, that it is used from the beginning, when creating the object?

Hello sidlercom80,

We advise against setting ZOrder directly as noted here and I wouldn't have any suggestion for doing so.

We would be able to change the ZOrderType, which would specify if we should use the normal Z-Ordering, always first, or always last.

As for observing the result of setting ZOrderType in a DrawingTool, I have made a short video:
