newbie scatter plot

mwalsh

1st day with JMP!

i have X, Y, Z data.  the X and Y are geographical grid data, like a football field.  The Z data are various sizes of rocks.

I want to make a scatter plot to visualize the location of the rocks.  BUT, i want to be able to group the rocks into custom size ranges (say; small, medium, and large) that i define.  On the graph, i would like to select a custom color that represents my custome size range (small = blue, medium = green, large = red).

Then i would like the ability to turn off or on the display of my custom sizes: for example, show the X, Y location of all the big rocks only.  Or show the X, Y location of the small and medium (but not the big)

 

This is probably so simeple, that its not obvious.

Thanks!

Hi @mwalsh,

 

I would try Graph Builder for this (https://www.jmp.com/support/help/14/essential-graphing.shtml).

Graph Menu and then Graph Builder.

1. Drag X into X Axis
2. Drag Y in Y Axis
3. You can also put Z into Size seciton and the points will be sized based on rock size

To get the coloring you want, you might try making a new column (https://www.jmp.com/support/help/14/add-columns.shtml) called Size Group and create a formula in that column (https://www.jmp.com/support/help/14/formula-editor.shtml) that looks something like this:

If(
	:Z <= 15, "Small",
	15 < :Z <= 30, "Medium",
	"Large"
)

Then you can use that for the color section of Graph Builder and also use it for the local data filter (https://www.jmp.com/support/help/14/local-data-filter.shtml).

I have attached a JMP data table called Rocks.jmp for an example. Click on the green triangle next to the item called Y vs. X in the upper left part of the screen to run the saved script that gives you an example of what I think you want.
