Feature request - Add options to Draw. functions

[ttodua]

many flexible things could be added to Draw. functions, like:

1) to have z-index (i.e. https://ninjatrader.com/support/help..._rectangle.htm ): so the draw should happen behind bar or in front of bar (not it is in front of bar and hides the bar. we cant set it to be in the back of the bar).



2) Draw.Arrow/ Dot ...etc... to have "Size" option.

and other simple things will be nice! otherwise we have to use extensive coding on "OnRender" With Sharpdx and hard things...

Hello TazoTodua,

Thanks for your post.

What you are requesting can currently be done although it may not be as convenient as perhaps you are wanting. Please review the options presented below and let me know if you still want to have us enter a feature request as you have stated.

You can manually control the z-order to manipulate the layering of objects as you wish, as you might suspect everyone wants it done differently (order wise) so this control allows anyone (don't need to be a programmer) to layer the draw objects as needed. Please see " How to change the z-order (paint order) of a chart object" in: https://ninjatrader.com/support/help...rt_objects.htm

From a programming point of view you can control the individual elements as you wish. With reference to: https://ninjatrader.com/support/help...us/?charts.htm even though this is in the "OnRender" section, you can still apply to Draw methods as they do use OnRender. For example (and see screenshot):

Dot myDot = Draw.Dot( this, "test"+CurrentBar, true, 2, Middle[2], Brushes.Fuchsia);
myDot.IsSeparateZOrder = true;
myDot.ZOrder = -10000; // draw behind bars

TriangleUp myUpt = Draw.TriangleUp( this, "test1"+CurrentBar, true, 1, Middle[1], Brushes.Blue);
myUpt.IsSeparateZOrder = true;
myUpt.ZOrder = -10001; // draw behind the Dot

Reference: https://ninjatrader.com/support/help...ratezorder.htm

The Draw arrow/Dot size question can be addressed in another alternative or two that can be done today:
1) Use a plot instead, where you can change the size as needed. this is a limited approach but is easily implemented, you can set the plotstyle to Block, Cross, Dot, Square, Triangles left, right, up down.
2) Use Draw.Text(), select a drawing font such as wingdings, you can find all sorts of things to draw and can easily change the font size.

excellent answer as alwyas!

btw, yes about arrows, it could have been just good if there was size option.
creating font (initlialization fo SImpeFont or etc.. or creating additional plots) are not as conveninet, as just easily rememeberable one-line function.

Hello TazoTodua,

Thanks for your reply.

I will submit a feature request to allow for size specification in the Draw. statements.

I will update this thread when I have the SFT number.
