RK's Framework 01 - Auto Color Gradient

This started as a personal arrays study, but after a few tests I decided to made a framework to get my own scripts simplest, lighter and faster.
And now I'm sharing with you guys.

Is very simple to use:

• Copy evething inside "RK's Auto Color Gradient Framework" block;
  
• Paste anywhere before the plotting;
  
• Declare the color variable name calling the function "f_autocolor(___, ___)" with the source you gonna plot and the size of the scale do you want to use to compare the data.
  

Feel free to use.

Hope brings some profits for you guys!!

Release Notes:

Version 1.1 notes:

• Put the script link on the code;
  
• Now the choice of the theme is outside the function;
  
• I deleted the reverse input and put the explanation to how reverse the scale;
  
• And I wrote a simple text to help if anyone wants to add their own color scale gradient.
  

To change the direction of the gradient scale, just invert the math sign of the source with a simple (-).

Release Notes:

█ PATCH NOTES: Version 1.2
