Hello Malone,There are two spots within the code where 'Squared.Histogram' is used. Just change both to 'Histogram.' This will reduce the widths of both the buy/sell colored bars. Note: there should not be a period before Histogram.
There are actually 5 lines within the code that use "Squared_Histogram" Are you saying change all 5 instances? I tried and I still get the fat square lines? In addition, most instances are written "BuyVol.SetPaintingStrategy(PaintingStrategy.SQUARED_HISTOGRAM);" and you said remove the period, so we write it as "BuyVol.SetPaintingStrategy(PaintingStrategyHISTOGRAM);" Just curious because following your directions literally, it doesn't work. Please help.
