If I flip my waterfalls around using coord_flip() in ggplot2 the "start" bar is on the bottom and the total on top, when most would expect to read top to bottom.

For example:

waterfall(
  tibble(category = letters[1:5],
         value = c(200, -20, 4, 20, -5)),
  calc_total = TRUE,
  fill_by_sign = FALSE,
  put_rect_text_outside_when_value_below = 50
) + coord_flip() 

I would typically add + scale_x_reverse() to my ggplot object, but in this case it results in:

Scale for 'x' is already present. Adding another scale for 'x', which will replace the existing
scale.
Error: Discrete value supplied to continuous scale
In addition: Warning messages:
1: In Ops.factor(x) : ‘-’ not meaningful for factors
2: Transformation introduced infinite values in continuous x-axis 

I love the package a lot. However, I didn't find a way to adjust the size of the text in X axis? Am I missing something or will this be in the future version?

Thanks,

I'm loving your waterfalls package and am so glad I don't have to build these up from scratch! Thank you so much for making this available.

I've run into an interesting edge scenario, however. I like to flip my waterfalls around using coord_flip() in ggplot2. But when I do, the text labels get bumped around.

For example:

waterfall(
  tibble(category = letters[1:5],
         value = c(200, -20, 4, 20, -5)),
  calc_total = TRUE,
  fill_by_sign = FALSE,
  put_rect_text_outside_when_value_below = 50
) + coord_flip() 

I'm beginning to dig into the code and if I cook up a solution I'll send a PR. But I wanted to register the issue first.

Great package indeed. Slight drawback: in the case of negative elements being involved, the Y-axis gets stretched to the max value of the negatives, even in case that’s not necessary because it’s only part of a more positive calculation. Any chance of a fix, Hugh?

Love the chart, but I want to add some axis labels and I can't. Reproducible example:

waterfall(values = round(rnorm(5), 1), labels = letters[1:5], calc_total = TRUE) + ylab("Why can't I add a y axis label?")

My gratitude to you for this package.
I made a small hack to work around a limitation:
Using coord_cartesian(ylim=c(0.6, 0.72)) to zoom in to plot caused my rect_text_labels to land outside of the range and disappear. Not currently in a position to submit a pull request due to work firewall, but my fix was to replace rect_text_labels_anchor = "centre" with rect_text_labels_anchor = 0.05 and treat it as numeric. Then replace the two places that 0.5 were used to set it with the var name. Now, I can set it at 0.9 when combined with the coord_cartesian and the rect_text_labels no longer drop.
