Stripchart with Stacked Points

[Dario Strbenac]

I have not been able to create a stripchart with stacked points, when they overlap. Can someone show a minimal example for points that are from two categories ?

My current code is :

ggplot(data.frame(expr = expression[geneRow, ], groups), aes(x = expr, y = groups)) + geom_point(aes(colour = groups)) + scale_colour_manual(values = c("red", "blue"))

Have you tried dotplot?

Cheers,

Roman

Thanks for the suggestion. I am creating a horizontal stripchart. It looks wrong, as you can see. None of the data is aligned to either category. If I simply switch the arguments to x and y in aes and set binaxis to "y", I get an appropriate vertical stripchart that is correctly aligned. Is it a bug ?

Can you distill your problem into a small, reproducible example?

Cheers,

Roman

Yes.

library(ggplot2)

ggplot(mtcars, aes(x = factor(cyl), y = mpg)) +
  geom_dotplot(binaxis = "y", stackdir = "centerwhole")

ggplot(mtcars, aes(y = factor(cyl), x = mpg)) +
  geom_dotplot(binaxis = "x", stackdir = "centerwhole")

I want the second version to be like the first, just horizontal.

I am using version 0.9.3.1.99 in R 3.1.0.

What if you add a `coord_flip()`?

ggplot(mtcars, aes(x = factor(cyl), y = mpg)) +

  geom_dotplot(binaxis = "y", stackdir = "centerwhole") +

  coord_flip()

Cheers,

Roman

Thank you. That resolves my problem. I need to learn more of the basics.
