I have a column with numeric X values and another with numeric Y values. The X and Y values each contain a minimum and maximum value for a series of observations, such as

obs dimension min/max value

1 X min 1.1

1 X max 1.5

1 Y min 0.9

1 Y max 1.25

I have 5-10 observations, each with coordinates like these. I would like JMP to draw rectangles on an (x,y) plane with those coordinates. Can anybody tell me how to do this?

Thanks.

Solution

Here is an example of taking your data and drawing a rectangle

```
Names Default To Here( 1 );
dt = New Table( "Untitled 18",
Add Rows( 4 ),
New Column( "dimension", Character, "Nominal", Set Values( {"X", "X", "Y", "Y"} ) ),
New Column( "min/max", Character, "Nominal", Set Values( {"min", "max", "min", "max"} ) ),
New Column( "value", Numeric, "Continuous", Format( "Best", 12 ), Set Values( [1.1, 1.5, 0, 1.25] ) )
);
dtSplit = dt << Split( Split By( :dimension, :Name( "min/max" ) ), Split( :value ), Sort by Column Property );
New Window( "Example",
Graph Box(
Y Scale( 0, 4 ),
X Scale( 0, 4),
Pen Color( "Green" );
Pen Size( 2 );
For( i = 1, i <= N Rows( dtSplit ), i++,
Rect( dtSplit:X min[i], dtSplit:Y max[i], dtSplit:X max[i], dtSplit:Y min[i], 0 )
);
)
);
```

Solution

There is very good documentation on Creating Maps in the Essential Graphing guide:

Help==>Books==>Essential Graphing

In JMP 13 it is Chapter 15, starting on page 303

I suspect your issue is placing the map on your desktop and getting JMP to be able to find it there. In my use of these maps, I always place them in the AutoLookup folders, and documented in the Essential Graphing guide

Solution

What I suspect that is going on, is that you are not defining the 4 points of your rectangle properly. Since with a Shape Map, what you are really defining are polygons, they must be defined in a continuous order. i.e. (top,left), (top,right), (bottom,right), (bottom,left).

Thank you, that does what I want. I was also thinking I might want to do this via creating a custom map, but I can't seem to get that to work. I follow the example in the sample help file but I keep getting the message in graph builder that the shape file is not found. I created the -Name and -XY files with the same shape ID column. In the -NAME file I assigned the shape name definition role to the name of my shape(s). I then created a new file with those names and some data and assigned the shape name use role to the column with the names - I put both the -NAME and -XY files in a new folder on my desktop and pointed to that folder in the shape name use role to tell JMP where to find the files.

I must be missing something - possibly where the paths to the files since I put them in a folder on my desktop. If anyone has any idea how I may be going wrong, I'd appreciate some tips.
