to change the scale of axes) in the usual way by double-clicking on it.It is very easy.

You will, therefore, need to substitute your own variable names into this syntax. This syntax assumes there are two variables, min (y-axis) and max (x-axis), which we wish to scatterplot.

In later versions of SPSS (18 and 19) the 'jitter' and other graphical options are no longer available in the menu bar and can only be done using the SPSS syntax given below. You can use this tab to 'jitter' both x and y co-ordinates in the scatterplot so all overlapping points are then visible. Double click on the plot and then on any data point. This is only available using the Interactive mode: Select Graphs > Interactive > Scatterplot. In versions 13 to 16 of SPSS there is an option for 'jittering' points in the graph menu bar. The use of open instead of solid shapes also helps to see the jittered points. See this and other helpful comments by Steve on the Do's and Don'ts of graphical plotting in the MS Word file located in the 2011 EDA Graduate talk zip file located here. He suggests an alternative to the XNEW in the above syntax given below. Steve Simon describes jittering as a slight random shifting of data to avoid overprinting. You can also modify the above script to jitter only in the horizontal direction as below: DATA LIST list / x(f9.3) y (f2.0). The above process, whereby concurrent points are plotted so they are visible individually on the scatterplot, is called jittering. IF (x EQ LAG(x) AND y EQ LAG(y)) copy = 1. The new values which are now all unique (ynew) can then be plotted against x. The below syntax uses the rv.uniform function in SPSS to add a small random amount to the y values when an x,y combination has previously occurred. One way of disentangling this is to add a proportionately small amount to the observed values of one of the variables, say, y. A scatterplot will only, however, show one point for each unique x,y combination regardless of the number of observations that share this combination.

Sometimes the same co-ordinates are shared by more than one observation. How do I scatterplot observations which have the same set of co-ordinates?
