i plotted this indicator and the code snippet is
Add(new Plot(Color.FromKnownColor(KnownColor.Black), PlotStyle.Square, "Plot0"));


Later in the code i do a
Plot0.Set(1);

In which panel do you plot this and what is your autoscale setting then?

[junkone]

autopscale=true
panel=5

Ok, if you try this with for example SMA(20)[0] you will notice if you connect a constant value square it will become a line, so this is what you see. Same goes for the hash style.
