Color your bars!
You can easily plot multi colored charts using both Plot function and
graph.. variables. All you need to do is to define array of color
indexes. In the following simple example up bars are plotted with
green and down bars are plotted with red color:
col = IIF( Close > Ref( Close, -1 ), colorGreen, colorRed );
Plot( Close, "Price", col, styleBar );
The same can be achieved using old-style graph... variables:
graph0barcolor = IIF( Close > Ref( Close, -1 ), colorGreen,
colorRed );
graph0style = styleBar;
graph0 = Close;
graph0name = "Price";
The next example is essentially the same with the difference that we
plot volume instead of the price chart:
col = IIF( Close > Ref( Close, -1 ), colorGreen, colorRed );
Plot( Volume, "Volume", col, styleHistogram | styleThick );
Hope you enjoy your charts in new colors!
