Hidden or transparent Bars

In Waterfall and Box plots the bars do not start at zero and the space underneath the bar is transparent. I am trying to create a horizontal bar chart to depict a range between 2 values (pretty much a box plot in landscape). I am doing this by creating a stacked bar with a calculated “hidden” value. However, I can only colour the hidden bar white to match the background, which colours over the grid lines on the chart, what i need to do is colour it transparent so i can see the underlying gridlines. is this possible

The alternative would be a horizontal box plot

Hello @j_j_Ramsay !

to my knowledge you can not make a bar in a chart transparent or change the opacity.

I will mark this as a feature request for the Quicksight team!
