hello guys, yesterday i made a code and recived three values s1= -2.401, s2= -2.862, & s3= -3.205. Now i want to plot a histogram for these values with distance where s1 goes from 0.5m to 1m, s2 goes from 1m to 1.5m, and s3 goes from 1.5m to 2m.
I'm very new in matlab and need guidance on how to make histogram for situations like this. please help me. Thank you so much

@Yash Raj Haldaniya - you perhaps want to defined the edges as indicated at bins with bin edges.

Try this:
s1= -2.401;
s2= -2.862;
s3= -3.205;
data = [s1, s2, s3];
% s1 goes from 0.5m to 1m, s2 goes from 1m to 1.5m, and s3 goes from 1.5m to 2m.
edges = [-inf, 0.5, 1.0, 1.5, 2, inf];
histObject = histogram(data, edges);
grid on;
title('Histogram of s', 'FontSize', 20)
xlabel('Value', 'FontSize', 20)
ylabel('Count', 'FontSize', 20)
% Note: all values are negative and thus will all fall into the first bin.

it helped me alot in understanding how histogram works in matlab.. but this resultant histogram is not what i wanted. i want an histogram column of s1 height from 0.5 to 1 and then s2 height column from 1 to 1.5 and so on.
but still thank you for helping me understand histogram this much. I'll keep looking for more answer or videos till i get my desired histogram.

Then you don't want a histogram/distribution, you want a bar chart of the actual values:
s1= -2.401;
s2= -2.862;
s3= -3.205;
data = [s1, s2, s3];
bar(data);
grid on;
title('Values of s', 'FontSize', 20)
xlabel('Index', 'FontSize', 20)
ylabel('Value', 'FontSize', 20)
yes this is indeed what i wanted it to look like. I'm curious if there is any function to combine these bars and get a line graph?? you getting what i mean?
