Plotting histogram

[2Look4me]

I'm trying to plot a simple histogram, the difference of two moving averages.

Diff.Set(MA2[0] - MA3[0]);

if (Diff[0] > Diff[1] ) {
BullBar.Set(Diff[0]);
}
else if (Diff[0] < Diff[1]){
BearBar.Set(Diff[0]);
}

I need some help figuring out why I'm getting these problems (see attachment):
* Green & Red bars are plotted together
* Declining Red Bars and Rising Green Bars are not plotted consistently
* Once I refresh the chart, all these issues are gone until it reappears with new plots

Thanks in advance.

Hello 2Look4me,

Thank you for your post.

Try setting the opposite plot to zero:

Diff.Set(MA2[0] - MA3[0]);

if (Diff[0] > Diff[1] ) {
BullBar.Set(Diff[0]);
BearBar.Set(0);
} 
else if (Diff[0] < Diff[1]){
BullBar.Set(0);
BearBar.Set(Diff[0]);
}

Thanks Patrick, I worked on that for hours, but it didn't cross my mind.

You just need a single plot and no additional DataSeries.

private Color upColor = Color.Lime;
private Color downColor = Color.Red;
Diff.Set(MA2[0] - MA3[0]);
if(Diff[0] > Diff[1])
   PlotColors[0][0] = upColor;
else if (Diff[0] < DIff[1])
   PlotColors[0][0] = downColor;
else
   PlotColors[0][0] = PlotColors[0][1];
