How do I display several lines of Comments on the chart?

New comment
 

The Comments function draws a simple text line in the upper left hand corner of the chart -- sometimes even on top of another indicator's comments. How would I draw two lines, one beneath the other (as if there had been a carriage return)?

Or, said another way, "How do I position Comments on the chart?"

 
Comment("\n Line 1\n Line2 \n Line3");

Comment("\n Line 1\n Line2 \n Line3");

Thank you, thank you, thank you. Have some fun today.

Well, it sorta looks like the Comments for several indicators don't play well together. That is, my indicator displays a Comment (perhaps spaced down a few lines), and then -- when another indicator displays its Comment -- my Comment disappears.

Any ideas?

  
Hello,
Chart parameters measurement may be useful for text positioning:

Every Comment() call wipes out prior Comment() calls, yes.

There are two types of text objects you can draw. One uses pixels reference to window corners for positioning,

the other uses a time/price coordinate. Both support only single line of text per object.

  
To maintain our objects on the chart, including text objects, regular resetting and redrawing may be required:

ObjectsDeleteAll () ;
... 
ObjectCreate     (...

ObjectSet        (...
ObjectSet        (...
... 
ObjectCreate     (...

ObjectSet        (...
ObjectSet        (...
... 
WindowRedraw     () ;
