Thanks User422070. Of cause there is a way, I always feel that
with ACSIL, the only limit is our imagination. There are few
steps, 1st you need to find out the exact symbol string by using
sc.Symbol variable, i.e. 'NFLX' 'CMG' etc, save each text image
to file like NFLX.txt, CMG.txt, then inside 'if (!sc.Index)' block,
load a text file according the symbol on the chart, you are done.

if (!sc.Index) {} is only executed once, but each time you change
the symbol on a chart, the study will be re-loaded, meaning,
if (!sc.Index) {} will be executed again, so, it feels like logo
is "automatically" changed every time you change the symbol, although
no coding is involved. It is easier to change the study in post #17
as a function (above all study functions).

If you are not into coding, there is a quick dirty way by changing 3rd line in post #17:
SCSFExport scsf_ASCII_Art(SCStudyInterfaceRef canvas)
to SCSFExport scsf_NFLX(SCStudyInterfaceRef canvas), also:
canvas.GraphName = "ASCII Art"; to canvas.GraphName = "NFLX";

Copy and paste from 3rd to end and change study and graph names for another stocks
now you have multiple studies in TextToImage.dll, then you can pick one of them along
with other studies you use for every chart, save them as a study collection: i.e.
NFLX.StdyCollct.

user8888, not sure what you are trying to achieve, I would like
to imagine that background would have negative impact to your judgment.
If you just want some horizontal colour stripes based on price levels,
then you need 2 subgraphs for each stripe, set each one of those 2 subgraphs
to whatever value you need, and one as Fill Top, the other as Fill Bottom
(see attachment)

for (int IndexCount = sc.IndexOfLastVisibleBar; IndexCount >= sc.IndexOfFirstVisibleBar; IndexCount--) {
SubgraphTop[IndexCount] = MyLevel_1;
SubgraphBottom[IndexCount] = MyLevel_2;
}

Hope that would help.
