Bar Graph with 3 variables

Afternoon All

I am looking for some help with a bar graph with 3 variables. I have drawn what the graph should look like as well as what the source data looks like. How do I create the graph. The example graph and data is here: https://drive.google.com/file/…pZ0pkb0U/edit?usp=sharing

Please help, not sure if I should be laying my data differently.

Thanks
