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?

I have continuous values.
But can you let me know a bar command as well?

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

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