You will need to read the text file, get the values and store them in an array or another construct.
You can then plot a graph inside the picture box using classes from System.Drawing.Drawing2D.

As far as checking whether the file has been loaded or not goes, set a boolean when the text file is read.
If the user clicks on plot and this flag is not set, it means the file has not been loaded.
Simply show the error message.
