How can I display overlapping data points on a scatterplot?
I have a problem displaying my SPSS data. I have got about 250
values in 2 catagories (=sample size), which I want to display in a
single graph (scatterplot?). The vast majority of the values in both
catagories are 0. Only 15% in catagory 1 are elevated (range 0-40) and
20% in catagory 2 (range 0-50).
My problem is that my data points (not elevated)are graphed on top of
each other, and you cannot tell from the scatterplot how many data
points each symbol on the graph represents, not even roughly.
I tried jittering and using the "sunflowers" option in SPSS.
The sunflower option did not help, because the amount of normal values
is too big to be clearly displayed. Jittering did not help neither,
because the SPSS-graph program is jittering only vertically and not
Maybe anybody has an idea how to display my data.
Any idea which graph data exploration program I may use?
Thanks for the help
