Empty there, even though the colour is set in the code. With all that said, the positive result was there, but it disappeared, no matter how ridiculous it sounds).
Then a short code reproducing the problem would help to sort it out.

It goes something like this.
zfs:
Like this.

This is how the values after the short name will appear

for (int i=0;i<=5;i++)
    {PlotIndexSetDouble(i,PLOT_EMPTY_VALUE,0);};
This is about the order in the buffers. https://www.mql5.com/ru/forum/12882#comment_539990
В каком порядке делать SetIndexBuffer() и зависит ли он он порядка директив #property indicator_x ?

может ли кто-то на пальцах обьяснить правила привязки индикаторного буфера к опр.
And how it helps me, I don't understand anything). Something can be changed to make it work, but it's still crooked, and I'd like to know more about it.

Total chaos and mess. ) Here's a working version (corrected the mistakes and brushed it up):

How does it work

if(_ViewInd==Line){
}
   else{

if (_ViewInd==Candles)
else

if

enum ViewInd
  {
   Line,               // линии
   Bar,                // бары
   Candles             // свечи
  };

?

Double-check all conditions and brackets, and without a loop, set the buffer properties linearly, order from the link above.

A loop is not needed there at all. More precisely, the property only needs to be set for one buffer, in all mapping options.

Generally yes, but if there are a lot of buffers, it's shorter :-) although I don't do that. It's easier for me to read linear portraits.

In fact, there can be so many buffers (max 512), that it's much harder to read the knitting without loops. ) In this variant there is just one buffer.

Great). Thank you. Like clockwork. The cognac is chilling).
