Drawing lines and text in window space

[muthaf]

Hi,

Does anyone have any examples of drawing objects such as lines and text with window based parameters rather than bar relative parameters? Is this possible at all?

Thanks,

Hello Rich,

You can do this with Shapes, Images and Text, but not lines. You need to use the flags RELATIVETOLEFT and RELATIVETOBOTTOM. There is also RELATIVETOTOP. When you use these flags, the first input parameter becomes the number of bars from the left edge of the window for RELATIVETOLEFT. With RELATIVETOTOP or RELATIVETOBOTTOM, the second input parameter becomes the number of pixels from the top or bottom edge of the window.

function preMain() {
    setPriceStudy(true);
    setStudyTitle("test");
    setShowCursorLabel(false);
    
}

var bEdit = true;

function main() {

    if (bEdit == true && getCurrentBarIndex() == 0) {
        drawShapeAbsolute(3, 20, Shape.CIRCLE, null, Color.lime, 
            Shape.RELATIVETOLEFT|Shape.RELATIVETOBOTTOM, "myShape");
        drawImageAbsolute(5, 20, "SystemHappyFace", null, 
            Image.RELATIVETOLEFT|Image.RELATIVETOBOTTOM, "myImage");
        drawTextAbsolute(7, 20, "Text", Color.white, Color.navy, 
            Text.RELATIVETOLEFT|Text.RELATIVETOBOTTOM, null, 12, "myText");
        bEdit = false;
    }
    
    return;
}

ReltiveX-AbsoluteY

Hi Jason,

Is there a way to Draw a RelativeX-AbsoluteY text/Image/etc.?

The idea is to be attached to a bar (like in Relative) but have fixed Y in chart (like in Absolute/DrawPixel).

Note: I tried "RELATIVETOTOP/BOTTOM" flags in DrawRealtiveText and does not work.

Thank you.

Unless I misunderstood your question the following line should write TEST at relative bar index -5 and fixed Y coordinate of 100 pixels from the top of the chart.
drawTextRelative(-5, 100, "TEST", Color.blue, null, Text.RELATIVETOTOP|Text.BOLD, "Arial", 11, "test");

It should and it does, except when you are dumb enough to name one of your vars "Text" [or any other reserved name].

Thank you Alex,
