RemoveDrawObject

[Mindset]

I appreciate this might not be supported but if the answer is really simple perhaps you could point me in the right direction.

In your custom plot sample you draw a string like so....

graphics.DrawString("Lower left corner", textFont, textBrush, bounds.X + 10, bounds.Y + bounds.Height - 20, stringFormat);

As it has no tag how would I remove just that string ?
RemoveDrawObject("") needs a tag?

In this example, we are overriding the Plot() method. Each time this method is called its repainting that entire panel thus, there is no requirement to remove it. You would need to add logic in the Plot() method that would paint or not paint items you want.

Work around

Thanks Ray - I realised that I could put an if... else String.empty in my logic and then check if the str has a value.
That solved it.
It would however be worthwhile to be able to tag each graphics object with a name - perhaps you could add that to your future development.

I am glad its resolved. At this level, you are programming purely against the graphics class in .NET and not at the NinjaScript layer. If you want tagged draw objects you would have to use NinjaScript methods.
