Continuous red ribbon problem

[hetong007]

I use the following code to try the ribbon feature:

getSymbols("SPY", from = "2001-01-01")
difference = SPY[,"SPY.Open"]-SPY[,"SPY.Close"]
decreasing = which(difference<0)
increasing = which(difference>0)

colors = rep("transparent", nrow(dydata))
colors[decreasing] = "red"
colors[increasing] = "green"

dydata=SPY[,"SPY.Close"]
dygraph(data=dydata, ribbon=list(colors=colors, height=0.05, pos=0.02))

The result looks like:

I zoomed in:

Notice the last part of the ribbon stays red.

I tried to change the height and pos of ribbon but didn't help.

This appears in my firefox, chrome and RStudio viewer.

Thanks for reporting. I was able to reproduce it and filed it here: https://github.com/danielkrizian/dygraphs/issues/18

It is not related to either height or position parameter. If looked closely on the right side of the ribbon while panning slowly to the right, there are traces of correct colors on the bottom pixel row of the ribbon, but they are overlaid with incorrect (red) color

Thanks for the reporting! The fix for Dygraphs Ribbon plugin was applied and the corrected version is available at http://danielkrizian.github.io/dygraphs/

@hetong007 , I merged the ribbon fix (thx Petr) into master, should work now if you reinstall.
