I want to create a bar graph with following qualities:
- Bar itself is split into 3 color categories, indicating portions between variables (individual y-axis from 0 - 100 %)
- Overall bar height indicates another variable height (individual y-axis)
So in total the data has 3 dimensions and it combines pie chart qualities to bar graph. This would be very nice way to visualize the data as I'm conducting near infrared spectroscopy analysis and want to compare thickness values in addition to absorption.
I think I need combine multiple y-axis with stacked groupping style (as in the picture below).
How to create this kind of bar graph?
