drawTextAbsolute cpu issue

[dloomis]

I use drawTextAbsolute to put a button on the screen and notice a large increase in cpu usage.

Is there a way to reduce cpu usage, perhaps with getBarState()? some other trick?

Hello David,

Without seeing your code, my guess is that you are calling the function on each execution of your formula. Also if you don't specify a unique tag name, you may be drawing multiple buttons on top of each other. You really only need to draw the button once, so use a global flag to control this. Here's an example.

var bButton = false;

function main() {
    
    if (bButton == false) {
        drawTextAbsolute(bla, bla, bla ... , "Unique Tag Name");
        bButton = true;
    }
    
}

Thx again, Jason, that was a great solution.

MY defintion says

drawTextAbsolute(xBar, yValue, Text, [FGColor], [BGColor], [Flags], [FontName], [FontSize], [TagName], [cx], [cy])

and if I change the tagname to 11, the box shrinks in size compared to tagname=12.

AM I missing something?

Also, I have two butons, both with tagname 12, is that a problem?, doesnt appear to be.

The 12 I was referring to was the font size, not the tagname, sorry for the confusion
