Solve problems, and share tips and tricks with other JMP users.
I came across this earlier post where using fit Y by X was suggested to plot histograms besides the axes for a scatter plot.
This has multiple drawbacks however, taking the iris.jmp datatable as an example
- you cannot show split the histogram per group (species column)
- you cannot switch the histogram to kernel density
a much nicer visualization is possible in ggplot2. Can below visualization be produced in JMP?

I'm sure there are other ways to do this, but here is how I did it. I start by making four graphs instead of one, using each axis twice, like this:
If you click the points element now, it will remove all graphs and leave only a "blank canvas", like this:
Next, drag and drop the desired graph element into each quadrant. Points in the bottom left, histograms in the top left and bottom right (it looks wrong, but we will fix it in the next step):
Now for the "trick": we need to "ignore" one of the axes in each histogram, like this:
At this point, the graph should look like this. We are almost there.
Now it's just a matter of resizing the axes, hiding some unwanted labels, and adjusting the style to your liking:
Yes, this can be done in Graph Builder. Here's how it looks with JMP's default style and color settings. With some customization I think you could get something quite similar to your example above.
Here is a script that will generate the plot above, if you have the Iris dataset open:
Graph Builder(
Size( 568, 469 ),
Show Control Panel( 0 ),
Variables(
X( :Sepal length ),
X( :Sepal length ),
Y( :Sepal width ),
Y( :Sepal width ),
Overlay( :Species )
),
Relative Sizes( "X", [303 75] ),
Relative Sizes( "Y", [72 246] ),
Elements(
Position( 1, 1 ),
Histogram( X, Legend( 13 ), Histogram Style( "Polygon" ) )
),
Elements( Position( 1, 2 ), Points( X, Y, Legend( 5 ) ) ),
Elements( Position( 2, 1 ) ),
Elements(
Position( 2, 2 ),
Histogram( Y, Legend( 17 ), Histogram Style( "Polygon" ) )
),
SendToReport(
Dispatch( {}, "Sepal length", ScaleBox( 2 ),
{Label Row(
{Automatic Tick Marks( 0 ), Show Major Labels( 0 ),
Show Major Ticks( 0 ), Show Minor Ticks( 0 )}
)}
),
Dispatch( {}, "Sepal width", ScaleBox,
{Label Row(
{Automatic Tick Marks( 0 ), Show Major Labels( 0 ),
Show Major Ticks( 0 ), Show Minor Ticks( 0 )}
)}
),
Dispatch( {}, "Sepal length", TextEditBox, {Set Text( "" )} ),
Dispatch( {}, "", AxisBox, {Add Axis Label( "Sepal lengthz" )} ),
Dispatch( {}, "Sepal lengthz", TextEditBox, {Set Text( "Sepal length" )} ),
Dispatch( {}, "Sepal width", TextEditBox, {Set Text( "" )} ),
Dispatch( {}, "Sepal length", TextEditBox, {Set Text( "" )} ),
Dispatch( {}, "400", LegendBox,
{Legend Position( {13, [-1, -1, -1], 5, [0, 1, 2], 17, [-3, -3, -3]} )}
)
)
);

You can do this
It is a little tricky to do with the UI, but it is possible.
