 Hi Grzegorz,
You are correct. it works now.
One more question: can I turn gc_label 90 degree in plot?
Thank you

Isn’t a bracket missing after gc_label?

So it should be:

> ggplot(s8_plot, aes(fill=GTresult, y=cases, x=gc_label)) +

+  geom_bar(position="stack", stat="identity"))

Hello List,

I use ggplot to draw a stack bar chart. but I error message. please
look it below:

> ggplot(s8_plot, aes(fill=GTresult, y=cases, x=gc_label) +

+  geom_bar(position="stack", stat="identity"))

Error: Mapping should be created with `aes()` or `aes_()`.

GTresult and gc_label are character variables, cases is numeric
variable. How to fix the problem?

Thank you
