Graph of multi categorial variable

[Leena Ray]

Hello,

I have various variable binary 0 if the effect in unpresent 1 if it is present in my population
I would like to lake a graph where in the x-axis I have the name of the variable (var_1, var_2, var_3) and on the y axis the percentage of 1

I struggle a lot to do that... I succeed to do more complex graph but that one seems to be difficult to get.

If possible I would like to go beyond and plot the same graph but inside each vertical bar the proportion of the presence manifested by 1 of another variable var_4

Thanks for your help

Thanks for your answer, it is close to what I want but not exactly.
Like this I have the picture attached.
But instead of the bars Holter Neg I would like the percentage on the entire population (Holter neg + Holter Pos) and on the right keep the bars Holter pos.
The best would be that each blue bars are together, red etc...
Is something like this is possible ?
Thanks for the help
