Base.Plot

[I_Quant]

Hi

dont worry about replying Ninja I know this is a non standard item ... perhaps some kind soul could tell me what I am doing wrong.

I have a Plot Override to draw some lines and boxes which works perfectly for that. However here's the thing .. I also have three plots which I would like to see sometimes but when I add the base.Plot(graphics, bounds, min, max); statement I get a run time error where I am told that ..


5/9/2012 1:31:23 PM Default Error on plotting indicator 'PReceiver'. Please check the 'OnBarUpdate' or the 'Plot' method: Value cannot be null.
Parameter name: pen

I do use pens and brushes in the method but I cant spot what I am doing wrong (obviously compile works fine)

I also have a return if Bars== null in there.

any pointers would be appreciated.

cheers

Could you show some pseudocode of your custom Plot, so that we can see how exactly you are calling base.Plot()?

I have some code running in the overloaded Plot() method (which works fine). It seems that calling base.Plot() within my function doesn't matter one way or the other.

Can someone explain to me the idea of why I should call it within my Plot() method?

Thanks!
