I'm using xyplot in a very simple way---a scatter plot of several data sets. I'm having a problem getting auto.key to display different point characters.
The following produces a plot that employes different colors, all with pch(1), for the different groups, with a matching key. xyplot(Force~Time, rawData, groups=Sample, panel = panel.superpose, auto.key=TRUE) The following produces a plot that employs different symbols (and colors) for the groups, but the key still uses pch(1) for all groups. I assume I need to set some more general option, but haven't found it yet. xyplot(Force~Time, rawData, groups=Sample, pch=0:18, panel = panel.superpose, auto.key=list(space="right", pch=0:18)) What I would really like is a plot with different symbols, all with black color. The following works for the plot, but again has no effect on the key. xyplot(Force~Time, rawData, groups=Sample, pch=0:18, col="black", panel = panel.superpose, auto.key=list(space="right", pch=0:18)) Thanks, Steve Kennedy Stephen J.
