Raptor can u pls xplain the logic hw one line multi-color is displayed here..tht wud b nice!..this r codes available in ths forum

MirTD:

Please edit your post . . .

Use SRC

okwh 2013.03.14 00:37 #13

you can use DRAW_SECTION to set indicator buffer's style

Raptor

the code above generates multicolor line...can u tell what is the logic used in here? tnx

Simon Gniadkowski 2013.03.17 13:22 #16

RaptorUK:
Think about it . . . at the bar where the line goes from red to yellow or from yellow to red, at that bar the buffer for red and yellow must have the same value, otherwise you get gaps.

You have the code, read and follow it line by line and figure it out, you will learn in the process.
