The last update of RSG is online, I have added heatmaps which can be useful when having a lot of data to plot. To test it I have simulated data for 100 000 eyes, over 60 000 with target 0 with a mean and standard deviation postop SE conditioned to preop SE and age and with one operator having results different to the others.

This is the SE preop vs postop plot:




That is a thick cloud of points. Let's turn the heatmap on:




We can see now the points density, being green low density and red high density, we can also see that the points fall in fixed SE postop values shown by the red lines, also that preop there are more within -6 and -1 and that there are much less around 0 SE preop, as expected. At the bottom left we see that there are 62 239 eyes represented.

The following graph shows the graphic separated by doctor:




Well, it seems that Dr. E red cloud is less intense and larger, indicating a greater variability in the outcomes (it could also be that there are much less eyes than the others, but here all have the same, that can be easily checked in the histograms tab). It is also a bit lower than the rest so the mean SE is also lower that the others.

You can test it here.
