HORIZONTAL BAR PLOT WITH GAPS

Hello,

I have a set of data with a timestamp and the state of two machines. When the machine is turned on I have 1. If turned off, I have 0.

I would like to plot using horizontal bars when each machine is working. Also, I would like to plot the total time in minutes inside the bar.

Any ideas on how to do it?

Thanks a lot

Lucas

Here is the heatmap solution, but unfortunately it doesn't return the total time in bar.

clc;
clear;
close all;

M1 = [ones(1,6), zeros(1,4), ones(1,7), zeros(1,3)];
M2 = [zeros(1,5), ones(1,6), zeros(1,5), ones(1,4)]; 

t1 = datetime(2020,10,26,0,0,0);
t2 = datetime(2020,10,26,19,0,0);
t = (t1 + hours(0:19));

h = heatmap(t, {'Machine 1', 'Machine 2'}, [M1; M2]);

There is a helpful link at Stackoverflow, if you'd like to make it using barh. Also, it is possible to overlay the text with the color background and the total number, but you'd have to generalise the calculation and location, width and height to place it. This is totally doable and could be worthy of file exchange submission.
