Variable color shading of histogram bars

[Stevo]

Hi Everyone,
I'm trying to figure out how to make histogram bars colour shade. I've searched the forum for ideas and found Dave's good work for variable shading of chart bars:

Any clues on how to apply this technique to a histogram plot would be greatly apreciated.

Cheers,

What do you mean by "shading"? Changing the color of the histogram? If so I wrote an indicator that does this called BollingerPrecentB2 and you can find it here as an example:

However if you are using NT7 there is a new PlotColors[][] method that is better to use, and you can find an example of how to use it here by looking for indicator Bollinger_TripleState_v4NT7:

These will help also:

Hi Mountainclimber,
Apologies for not being clear enough. By "shading" I mean color shading each bar of a volume histogram, for example from light to dark red or light to dark green depending on the result of a calculation between trades at bid Vs ask.

by using something like:

HistoBarColor = Color.FromArgb(255, colorValue, colorValue)

Where the 'colourValue' is in this example a ratio of traded volume at Bid Vs Ask that determines the color.

'DaveS' used this in the below example to paint the price bars in this way.

The bit I'm stuck with is to get this to work within the Add() method to plot an indicator / ocillator.

Thanks very much for your sugestions, I'll have a good look at them. And yes I'm using NT7

Cheers,
Stevo

Stevo, unfortunately this is not supported per default - would you have snippet perhaps I can test, check into for you?

[mountainclimber]

Yeah, bert is correct. Post a bit of code that works that you have seen and show us how you are trying adapt it for your purposes. I haven't done something like that, but it sounds interesting.

I found this link, but don't have time to look into it unless you pay me!
