How can I plot multiple MACD's on the same screen?

How can I plot multiple MACD's on the same screen so that they chart on the same plot?

One would use an EFS file returning multiple MACDs.

Here is such a file:

function preMain() 
{
    setPriceStudy(false);
    setStudyTitle("MultiMACD");
    setCursorLabelName("macd(12, 26, 9)", 0);
    setCursorLabelName("macd(7, 13, 5)", 1);
    setCursorLabelName("macd(50, 20, 6)", 2);
    setComputeOnClose(true);
    
    setDefaultBarFgColor(Color.fushcia, 0);
    setDefaultBarFgColor(Color.red, 1);
    setDefaultBarFgColor(Color.green, 2);
 
    setDefaultBarThickness(2, 0);
    setDefaultBarThickness(2, 1);
    setDefaultBarThickness(2, 2);
    
    addBand(0, PS_SOLID, 1, Color.white, "ZeroLine");
    addBand(2.5, PS_SOLID, 1, Color.white, "AnotherLine");
    addBand(-2.5, PS_SOLID, 1, Color.white, "AnotherLine2");
       
    setStudyMin(-5);
    setStudyMax(5);
}

var macd1 = null;
var macd2 = null;
var macd3 = null;

function main() 
{
    if (macd1 == null) {
        macd1 = macd(12, 26, 9);
        macd2 = macd(7, 13, 5);
        macd3 = macd(50, 20, 6);
    }
    return new Array( macd1.getValue(0), macd2.getValue(0), macd3.getValue(0) );
} 

This EFS produces an indicator that looks like this:
