Sorry, I completely forgot about an example, so here one is but the
actually data does go up to 2007
Year Season percent_below
2000 Winter 6.9179870
2000 Spring 1.6829436
2000 Summer 1.8463501
2000 Autumn 3.8184993
2001 Winter 2.8832806
2001 Spring 2.5870511
2001 Summer 0.0000000
2001 Autumn 4.7248240
I tried adding stack=TRUE but it didn't do anything, so I am not sure if
I am doing something wrong with the coding. I also tried controling the
labels using scales=list(labels=NULL) but it didn't do anything, so not
sure what I did wrong. I know that I could have seasons as the
x-variable however in my graph I want each season vs. percent_below by
each year for each season. I also added a panel because I neede to add
a line to each season to show an upper and lower limit and they were
different for each season. I have tried barchart(percent_below ~
factor(Season), groups=Year) but it doesn't give me what I want. So
still not sure how to get rid of the x-axis labels and how to make the
bar widths wider.
Thanks in advance for the help
