How to ensure common Histogram-Axis among all groups in scatterhist in Matlab?

[poster]

I have the following problem with the scatterhist-function in Matlab:

data is a 1000x49 matrix.
prediction is a 1000x1 vector, with each cell as a integer-value in range 0-3

I expected the following to produce two scatterhist-Plots of the same data but with different subgroups (2,1) colored orange. So both Y-Axis-Histograms should display the same distribution (when the groups are summed up)

scatterhist(data(:,43),data(:,49),'Group',prediction==2,'Kernel','on','Marker','.');

Plot 1

scatterhist(data(:,43),data(:,49),'Group',prediction==1,'Kernel','on','Marker','.');

Plot 2

Now my question is:

• Do the Histograms in both plots not add up to the same total? (and my logic is flawed)


• or do the groups not share the same axis?
