Its only once you start using hotkeys and the keyboard you realise just how slow mouse clicking is.
Clearly your skill level is way beyond mine Richard but even if I make my own plot I still don't see how I can re write historical bars - sorry if it's simple but I just don't see it?
Are you referring to iterating through every bar on the chart each time I press the hotkey perhaps?

When you make a custom plot() method, you paint the chart when asked to do so by ninja. So... you can just not paint anything if you don't want to. So, it's as simple as doing nothing. Look at indicators that have custom plot() for examples of how to do it, but beware it will be confusing if you don't have any windows.forms experience.

Ok here is a start anyway.
Life is just too short to spend too much time on such basic stuff.
This will turn the EMA indicator on/off using Shift+H(ide) or V(isible).

BUT It reloads Ninja Script so has very limited value but you know I am not a programmer.....

if you want to override plot method to do nothing it should be fairly simple:

Code

 
public override void Plot(Graphics graphics, Rectangle bounds, double min, double max)
{
     if(!showPlots) return;
     base.Plot(graphics, bounds, min, max)
}

Ah, you're right. If he doesn't want to do anything unusual except not plot, then he can just let ninja take care of the rest. Now why didn't I think of that? I think my brain is hard-wired to equate custom plot() with pain.

Actually it was the drawing of the EMA line I struggled with!
The minute I go near x and y I just simply get confused.

Hadn't looked at this in a while and didn't realise people had responded.

The issue remains that 'hiding' the ema line proves elusive.
It may be that a clone() is required but again this may be beyond me to resolve.

Ref No Plot - yes I get that but it doesn't hide existing plots does it? It just stops plotting

This doesn't seem very elegant - but then it gets the job done with the minimum of fuss.

I have only tidied the code up a little and there are 'other' working bits in it but hopefully it will be useful to some.
If somebody more capable than me can make it better please feel free.
It doesn't feel good enough to include as an indicator download but maybe one of the moderators could comment on that?
You can turn the Moving average plot 'On' or 'Off' via toolbar button or keycode (Shift + H)

NB NT7 version only.

Still not entirely convinced by this indicator... but still this is an updated version - just some colour choices and a few minor code changes.
I find every now and again if you click the ema off and then add it say 20 bars later it doesn't update... if you keep the indicator as Calculate on Bar Close this doesn't seem to happen.
This should work in both 6.5 and 7 but I have NOT tested it on 6.5.

Here is a slightly updated version of Mindset's original.

Does the same stuff but I figured out how to refresh the chart after button toggle.

Thanks to Mindset.
