Add option to overlay numeric values on grid visualizations #32

Hey Scott,

I'm wondering if it's possible to include the actual value associated with the well in the final visualization. Like a heat map but with each well's value stamped on top of it.

Thanks, Cole

Hi Cole,

Yes you can add text to the plot with the usual ggplot functions like geom_text.

So for example:

library(platetools)
library(ggplot2)

df = data.frame(
    val = runif(96, 1, 10),
    well = num_to_well(1:96)
)

raw_map(df$val, df$well) +
    geom_text(aes(label=round(df$val))) +
    scale_fill_distiller()

image

However, you might have to play with the formatting and size of the label to make it fit well within the wells.

Hey thanks for the quick response. That's super helpful!

Feel free to close this issue, or am I suppose to? This is the first issue I've ever submitted so I'm not sure if this was the right place to ask the question. Thanks again!
