I attached a plotted fig that plotted by method. How can I get data from traction effort(y axis) and speed (x axis) and represent it in Excel?

Didn't you plot it? So you should already have the x and y data, right? So then simply use xlswrite().

Use the Add On Explore to install some of the File Exchange contributions you find from the above link, and try them out.
The plots are pretty simple; you could probably pretty much read them off by eye. If you want to try for higher resolution, try Image Analyst's code at https://www.mathworks.com/matlabcentral/answers/130306-how-do-i-find-the-distance-between-two-pixel-co-ordinates#answer_137530 to calibrate according to the grid lines and then to use the results to measure more precisely where the lines are.
