The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values.

IMed-box Graph

This type of graph lets you see how a large number of

 

 

 

 

 

 

 

data items are grouped within specific ranges. A box

minX

 

 

 

 

 

 

encloses all the data in an area from the first quartile

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(Q1) to the third quartile (Q3), with a line drawn at the

 

 

 

 

 

 

 

median (Med). Lines (called whiskers) extend from

 

 

 

 

 

 

 

either end of the box up to the minimum (minX) and

 

 

 

 

 

 

 

maximum (maxX) of the data.

 

 

 

 

 

 

 

From the statistical data list, press (GRPH) to display the

 

Q1 Med Q3 maxX

 

 

 

 

 

 

graph menu, press (SET), and then change the graph

 

 

 

 

 

 

type of the graph you want to use (GPH1, GPH2, GPH3) to

 

 

 

 

 

 

med-box graph.

 

 

 

 

 

 

 

To plot the data that falls outside the box, first specify

 

 

 

 

 

 

 

“MedBox” as the Graph Type. Then, on the same screen you

 

 

 

 

 

 

use to specify the graph type, turn the Outliers item “On”,

 

 

 

 

 

 

and draw the graph.

 

 

 

 

 

 

 

•Changing the “Q1Q3 Type” setting on the Setup screen can cause the Q1 and Q3 positions to change, even when a Med-box graph is drawn based on a single list.

IBar Graph

You can specify up to three lists for drawing a bar graph. The graph is labeled [1], [2], [3], and so on, corresponding to lines 1, 2, 3, and so on of the list used for the graph data.

•Any of the following causes an error and cancels bar graph drawing.

-A Condition ERROR occurs when drawing of multiple graphs is specified using the graph On/Off screen (page 6-3), and bar graph is specified for one of the graphs and a different graph type is specified for another graph.

-A Dimension ERROR occurs when you draw a graph with two or three lists specified and the specified lists have a different number of list elements.

-A Condition ERROR occurs when lists are assigned for Data1 and Data3, while “None” is specified for Data2.
