Using the code data, I would like to compare LCOH of six items with histogram.

Image is like the picture.

What is command for it?

[the cyclist]

It's clear to me whether you need histogram or bar, but you've got both answers.

The main difference is whether you have continuous (or effectively continuous) values that you want to be "binned", or whether you will be plotting a bar for every possible value.

[Minhee]

I have continuous values.

But can you let me know a bar command as well?

[the cyclist]

The link the bar function is in my answer, and it has many examples.

Answer 1

[the cyclist]

You can use the bar function to create it from your data. The link has several examples.

Answer 2

[Catalytic]

You can use the histogram command with hold to superimpose them.
