The arguments for Plot are: Data to plot (Array) Title (String) Color (Array) Style (constant) then the optional args the style cannot vary (ie. it can not be an array of styles, such as what iif returns), and it looks like you are confusing colors with chart styles. Your 'above the line' code works because you are using iif properly to return an array of colors. So the code should be: Plot( yFe50, "a", iif(tXa,colorRed,iif(aXt,colorWhite,colorAqua)), styleDots ); Now if you want to vary a solid line with a dashed line in the same graph, you can use the following trick: SolidCondition = <conditional that expresses when you want a solid line vs. dashed> Plot( iif( BarIndex() % 2 == 0 OR SolidCondition, yFe50, NULL ), "a", iif(tXa,colorRed,iif(aXt,colorWhite,colorAqua)), styleThick ); Basically, it just replaces the value of the line (yFe50) with interleaved 'NULL' values (which are not drawn) when the condition is false, to simulate a dashed line.
