In weka I load an arff file. I can view the relationship between attributes using the visualize tab.

However I can't understand the meaning of the jitter slider. What is its purpose?

You can find the answer in the mailing list archives:

The jitter function in the Visualize panel just adds artificial random noise to the coordinates of the plotted points in order to spread the data out a bit (so that you can see points that might have been obscured by others).
