I´m trying to alter a basic alluvial plot in order to fit my data and I have two separate issues:
- two of the categories (A1 & A2) within my main variable (index) are much much larger in relation to the others which makes the rest of the outcomes to look squeezed in.
- the second variable I´m using has also many categories in it which makes the legend too big to fit withing the margin of the graph
I use the following code_
ggplot(data = sni_long,
aes(axis1 = index, axis2 = Avdelning, y = freq)) +
geom_alluvium(aes(fill = Avdelning)) +
geom_stratum() +
geom_text(stat = "stratum",
aes(label = after_stat(stratum))) +
scale_x_discrete(limits = c("Index", "Avdelning"),
expand = c(0.15, 0.05)) +
theme_void()
and get the following graph:
when I tried the following code hoping to split my axis1 variable (index) in half:
ggplot(data = sni_long,
aes(axis1 = index,
axis2 = Avdelning,
axis3 = index,
y = freq)) +
geom_alluvium(aes(fill = Avdelning)) +
geom_stratum() +
geom_text(stat = "stratum",
aes(label = after_stat(stratum))) +
scale_x_discrete(limits = c("Index", "Avdelning"),
expand = c(0.15, 0.05)) +
theme_void()
I only managed to mirror the graph:
and as you see in both cases, the legend falls outside the scope of the graph :S
Edit: dataset here:
