Histograms show thin vertical lines #62

Open gusevfe opened 10 years ago

Hi,

when I try to view ENCODE histone modification signals and set histogram to have only one color, there are some thin white vertical lines in the figure. Is there any way to get rid of them?

Thank you.

This is quite hard to avoid when rendering each bar of the histogram as a separate rectangle on the canvas.

The solution is probably to special-case histograms to work more like how LINEPLOT glyphs are drawn. This might actually turn out to be a good thing from a performance point of view, too.
