Importing data from Excel can be done using the XLSREAD function, for example to read all data from myfile.xls:

A = xlsread('myfile.xls')

Or to only read a specific range from a specific sheet:

B = xlsread('myfile.xls','Sheet 1','B10:F28')

More information can be found in the documentation:

The file is not there. Correct the filename, or else find the file and put it in that folder.

If you prefer to use an interactive approach you can double click on the Excel file from the Current Folder browser and interactively import the data. As soon as the data is in your workspace you can use PlotTools to quickly create and customize your plot.

The Import Wizard GUI is presented on page:
