drawing lines relative to the top/bottom

[clearpicks]

is it possible to draw lines relative to the top/bottom in pixels? for example. from (0, 100) to (-20, 200), where 100 and 200 are pixels?

Hello Clearpicks,

You can use the Text.RELATIVETOTOP or Text.RELATIVETOBOTTOM flags with the drawText... functions to accomplish what you need. When these flags are present, the y parameter becomes a pixel value. There is also a Text.RELATIVETOLEFT flag which turns the x parameter into the number of bars from the left of the window.

You might also want to try using the drawTextPixel(xBar, yValue, Text, [FGColor], [BGColor], [Flags], [FontName], [FontSize], [TagName]) function. This allows you specify a x/y location in pixels. It assumes relative to top and left of the window, but you can also use the Text.RELATIVETOBOTTOM flag.

function main() {
    if (getCurrentBarIndex() != 0) return;
    
    drawTextPixel(0, 100, "drawPixel", Color.white, Color.navy, null, null, 12, "myText1");
    drawTextRelative(0, 100, "drawTextRelative", Color.white, Color.navy, 
        Text.RELATIVETOTOP, null, 12, "myText2");
    drawTextRelative(-20, 100, "drawTextRelative", Color.white, Color.navy, 
        Text.RELATIVETOTOP, null, 12, "myText3");
    
    return;
}

Hi Jason,

Are there corresponding flags for drawing lines relative to the top/bottom? Thanks.

Tall lines...

Clearpicks,

In my ECF code, I'm doing something like this, but I resolved the problem by drawing from 0 to 99999. There is no other real solution (that I'm aware of), just force in the values that will draw the lines you want.

Hello Clearpicks,

No, the drawLine... functions do not have a flag input parameter, but that would be a good suggestion for [email protected].

Hello Clearpicks,

Just thought of another idea for you to try. Add this non-price study to your chart and then overlay it onto the price window. This will give you the relative affect you're looking for. In this case the 80 and 20 would represent the percentage of the window from the bottom.

function preMain() {
    setStudyTitle("Fixed Lines");
    setShowCursorLabel(false);
    setStudyMax(100);
    setStudyMin(0);
    
    addBand(80, PS_SOLID, 2, Color.red, "top");
    addBand(20, PS_SOLID, 2, Color.red, "bottom");
}

function main() {
    return;
}

Thanks.
