getting user input in title and legend

the code is you want to create a graph showing the relationship of an ideal gas between pressure (P) and temperature (T).

the first 2 are Nitrogen, and oxygen the third will be ser input of gas. I created 2 figures. Figure (1) for all plots on the same axis, and the figure 2 is for sublpot of each gas.And ask the user to input the gas name. But how can I input the gas name from the user to the legend or title.

I hope that was clear.

I would use the inputdlg (link) function. You can also use input.

Use that to get the user input.

Then use the sprintf function to print it in the title or legend.

In addition to Star Strider's method, the user can directly edit titles and legend strings by selecting them on the figure itself (the user won't be prompted and will have to know how to edit these objects).

Just click on the white arrow, then double-click the title and/or legend to change the string.
