coloured squares on top corner of chart

[sam.burn]

Trying to work out how to put coloured shapes on the chart at the top that do not move and that you can change its colour of.
opposite the chart symbol label.

You can accomplish that using the drawTextPixel() function.
In the enclosed example you can change the color and the width of the colored block through Edit Studies

function preMain(){
    setPriceStudy(true);
    setShowCursorLabel(false);
    
    var fp1 = new FunctionParameter("Color1",FunctionParameter.COLOR);
    fp1.setDefault(Color.yellow);
    
    var fp2 = new FunctionParameter("Width1",FunctionParameter.NUMBER);
    fp2.setDefault(200);
    
}
 
function main(Color1,Width1){
    
    drawTextPixel(0, 0, " ", null, Color1, null, null, 10, "test", Width1, 15);
    
    return;
}
