Arrow Plot?

pmroz

Hello all,



I have data that looks like this:



Category  
Previous    Current

A             
5              
10

B             
30             
25

C             
0               
20

D             
3               
4

E             
20             
30



I want to create a chart that shows the magnitude and direction of
change, going from Previous to Current.  For example I would
have the Category on the Y axis, and show an arrow going from Previous
to Current in the X direction.  Here's my attempt at a crude
graph using characters:



A
|    ----->

style="font-family: monospace;">
B
|           
           
<----

style="font-family: monospace;">
C
|------------------->

style="font-family: monospace;">
D
|   >

style="font-family: monospace;">
E
|            
      ---------->

style="font-family: monospace;">
 
+----+----+----+----+----+----+----+----+

  0    5    10  
15   20   25   30   35   40



Is such a thing possible in JMP?  Failing that I'd be happy
with a chart showing the range covered by Current-Previous.



Thanks,

Peter

You can use add a graphics script to a graph (choose customize... in the dropdown menu when right clicking on a graph) and use the Arrow() function. I could not make it work in the horizontal chart platform, probably because categorical data are assumed there. By using overlay plot and transforming A-E into 1-5 I managed to get a graph that looks somewhat like your picture, however rotaded. Try the script below.
