setBar( type, barIndex, value | arrayOfValues )
This function allows you to adjust the value and/or the properties of a prior bar of a study being displayed. For example, if you are calculating and displaying 2 moving average studies in your script, you could use the setBar() function to change the actual value, color, line style or thickness of a previously-displayed value from either one of the studies or even both of the studies.
Parameters

Usage
//set the value of the prior bar of the first study you are returning
//from your script to 22.
setBar( Bar.Value, -1, 22 );
//set the value of the prior bar of the 4th study you are returning
//from your script to 25.
setBar( Bar.Value, -1, 3, 25 );
//set the line style of the third study returned from your script to PS_SOLID (3 bars ago)
setBar( Bar.Style, -3, 2, PS_SOLID );
//Assume your script is returning 3 values to be plotted. The following code will change
//the backround color of each study (at a point 10 bars ago) to blue, green and yellow respectively.
setBar( Bar.BgColor, -10, new Array( Color.blue, Color.green, Color.yellow ) );
