Hi verybody!

Please, I need help with a code.
I need to show an image or other into a strategy chart depends a variable value while the strategy price are moving.
As we cant use "public override void Plot()" function in strategy charts i am adding a external indicator in Initialize function, but how could I hide and show this images from strategy onBarUpdate function?

Thank you very much !


Indicator code...

public override void Plot(Graphics graphics, Rectangle bounds, double min, double max){

graphics.DrawImage(myImg,0,0);

}

If you draw an object in NT and give it a name, you can then remove it again as if the condition is no longer valid.

1) named obectrs :

Draw a rectangle :
DrawRectangle ("Ubox1", showScaled, barsago, Low, 0, High, Color.Red, Color.Red, 2);

Remove this rectangle :
RemoveDrawObject ("Ubox1");

2) In your case, if you draw with graphics.Drawimg, you need to repaint the hole screen, this can be
done with : ChartControl.Refresh();
but the screen might flicker

good luck

Thanks rleplae

I dont want to destroy or remove the image objects.
I need to show or hide this created images several times depending a variable value.

Some ideas? Thanks

Do you need to have an image or if the built-in shapes/text are sufficient ,
then i would recommend de first way, draw and remove if needed

Thanks again rleplae

I want load 2 images and hidde or show when i need, but if its not possible... how could i code the built-in shapes/text
