Cannot set axis.line limit correctly

[jernest1]

I would like a y axis line with tick marks beside the dendrogram. It should start at 0 and end at the y max, similar to the base plotting behavior. However, nothing I've tried works. The line runs past the y limits I set. Running a little past the y max is ok (as the base example does) but I would really like it to start at 0. How can I make this work?

hc <- hclust(dist(mtcars))

# Base example
plot(hc)

# ggdendrogram
ggdendrogram(hc) + 
  coord_cartesian(ylim = c(0, max(hc$height))) +
  theme(
    axis.line.y = element_line(),
    axis.ticks = element_line()
  )

Sorry for asking, but why would you prefer to do it with ggdendro over dendextend? https://cran.r-project.org/web/packages/dendextend/vignettes/dendextend.html#ggplot2-integration

@talgalili I don't have a preference as long as it's ggplot. If there's an easy way to add an axis line to a dendrogram similar to base plot using dendextend please let me know. In this case I'm asking specifically about ggdendro.

I'm not sure I follow, you show an example of how you've done it with code. Is that solution not good for you? Are you looking for another solution?

@talgalili I want the y axis to end at 0 like the base plot example. Notice how with ggdendro the y axis runs past 0.
