Histogram Question

[Bmatheny]

This is probably a stupid question, but how do I set a histogram to have a "center value" of 50 (originating the drawing of the historgram at 50 instead of 0 - which appears to be the default).

This of plotting a Stochastic %K indicator as a histogram with a center level at 50%. So anything below 50% would be plotted from 50% to ??. And anything above 50% would be plotted from 50% to ??

Thanks in advance.

NinjaScript is really cool. Should have started with it earlier.

Hi Bmatheny,

Thank you for posting.

While I do not know how to calculate for a histogram, there are plenty of histogram indicators available to look at and use as a resource from our support forum.

One that stood out when I looked was the CCI Histogram.

I will also leave this thread open for any of other members would be able to assist you in this matter.

Let me know if I can be of further assistance.

Thank you for your quick reply, but this code does not address the root issue of my post. This clearly shows how to custom color any histogram level beyond certain levels. But I'm looking to change the "Base Level" of a histogram from ZERO to some other value (like 50).

Is there any way to accomplish this?

Thanks

Hi Bmathenym,

Could you please provide examples of what you are trying to accomplish, such as picture, links or code from some indicator that you are looking at.

Thank you for your patience.

A histogram, by statistical definition, can only be based on zero as the y-origin.

What you can do for any oscillator, however, is shift the reference values. So, for example, you can make the oscillator plot from -50 to +50, or -100 to +100 instead of from 0 to 100. Then your histogram will plot on both sides from zero. If you shifted your plot from 0 to 100 to be -50 to 50 for example, then the original 50 will be 0, original 0 will be -50 and original 100 will be 50. All relative information is, therefore, retained; but absolute values will, of course shift.

Hi Bmatheny,

Thank you for the example.

The best method I can think of to accomplish this task would be to use the DrawLine() function to create your own kind of bar for graphing it. You can set your conditions for when the RSI is greater than and plot that way.

You would probably need to use a custom Plot to do that.
