I would like to experiment in ggplot with an idea. I have 10 points between 0-5 on the x axis and the corresponding y values for several data series. Now I am making a scatterplot connected with lines. To diffentiate between series types, I would try to use a linetype, where every dot/dash is replaced with an ‘A’, so instead of the lines, there will be a series of A-s. How could I do this? I tried to label every point, but since it is only 10/series, they are not really forming a continuous line. Any ideas?
ps. I realize it migt look horrible, but would like to give it a try first.
I’m not sure I’m imagining this correctly, but something like the following? Below, we interpolate the x-y series to place a later at the interpolated points.
library(ggplot2) library(dplyr) df <- expand.grid( series = LETTERS[1:3], x = seq(0, 5, length.out = 10) ) %>% mutate(y = rnorm(nrow(.))) %>% group_by(series) %>% summarise( xout = seq(min(x), max(x), length.out = 100), yout = approx(x, y, xout = xout)$y ) #> `summarise()` has grouped output by 'series'. You can override using the `.groups` argument. ggplot(df, aes(xout, yout)) + geom_text(aes(label = series, colour = series))
