Darkening grid lines on waterfall plot

[johnzhe]

Hi,

Just wondering if it was possible to darken the grid lines on a waterfall plot from grey to black.

I've tried setting the mainLayer in the waterfall function, to another ggplot2 theme but it produces other unwanted changes.

I had the same issue, someone solved it??
