I am a new one for JMP :-)

For example, I have 4 columns

Name Gender Score1 Score2:

Jason M 98 87

Alice F 67 78

Emma F 89 79

John M 70 89

Jennifer 76 65

I would like to generate a varibility chart (although the example only has 1 data for each people). I want to plot 2 curves (in different color for example) in 1 figure grouped by Gender, and connect the data with a line for each group. The x axis names need to be the listing order, like this

Thanks a lot!

I wasn't sure about Score 1 and Score 2. I assumed that the two scores provides the range for your error bars. That means I stacked the Score columns first. For the Name column I turned on the Row Order Levels property so that JMP would plot them in the order they appear in the data table.

At the graph builder I drug the Name to the X-axis. I drug the Score column to the Y-axis. I changed the statistic to be the Mean with an Error Bar using the Range. I then drug the Gender column to the Overlay field and added the connector line. Results look like below. The JSL is below the graph.

```
Graph Builder(
Size( 528, 465 ),
Show Control Panel( 0 ),
Variables( X( :Name ), Y( :Score ), Overlay( :Gender ) ),
Elements(
Points(
X,
Y,
Legend( 5 ),
Summary Statistic( "Mean" ),
Error Bars( "Range" )
),
Line( X, Y, Legend( 6 ) )
),
SendToReport(
Dispatch(
{},
"400",
ScaleBox,
{Legend Model(
5,
Base( 0, 0, 0, Item ID( "F", 1 ) ),
Base( 1, 0, 0, Item ID( "M", 1 ) )
)}
),
Dispatch( {}, "Graph Builder", FrameBox, {Marker Size( 6 )} )
)
);
```

You can create a new virtual column by right clicking on one of the variables in the column names in the Columns area, you can select Formula to create a new column in which you can concatenate the 3 column's values into one column, and then use that column to drag into the Page drop area

Re: how to plot an overlay variability chart

Graph Builder is what you want to use. It is documented in the Essential Graphics document

Help==>Books==>Essential Graphing

The below graph was generated interactively, using the Big Class sample data table.

Below is a script that also generates the above graph

```
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
Graph Builder(
Variables( X( :sex ), Y( :weight ), Color( :sex ) ),
Elements( Points( X, Y, Legend( 3 ) ), Line( X, Y, Legend( 4 ) ) ),
SendToReport(
Dispatch(
{},
"weight",
ScaleBox,
{Min( 44.3877551020408 ), Max( 164.387755102041 ),
Inc( 20 ), Minor Ticks( 0 )}
)
)
);
```

Re: how to plot an overlay variability chart

Hi, you can use also

Analyze --> QUALITY and PROCESS --> VARIABILITY /ATTRIBUTE GAUGE CHART

Re: how to plot an overlay variability chart

This is an extension of @txnelson and @gianpaolo suggestions.

- Sort your data by your grouping ( gender )
- Add a sequence column call it rowid which is just the row number (this is needed for GraphBuilder)

Below are 3 examples

- Variability which has only one connection color,
- GraphBuilder allows different colored connectors but can be combersome if you want a true overlay with an X-axis like datetime
- Bivariate with GroupBy allows colored connectors to match the group points, and here if you wanted x to be the original row order (like a Date axis) where the groups are spread, the graph will produce a true overlay

Re: how to plot an overlay variability chart

Thanks guys. Sorry, I didn't make it clear. Is there any possible way to plot like this?

Re: how to plot an overlay variability chart

Thanks Dan! It works! A further question. How I can I generate group plot in graph builder. Similar example as above

Name Gender Score1 Score2 Class

Jason M 98 87 1

Alice F 67 78 1

John M 70 89 2

Emma F 89 79 2

Patrick 65 98 1

Jennifer 76 65 1

Dan 100 99 2

Wendy 78 84 2

Would like generate 2 plots by class, just like when you using group in varibility plot:

Further more, if I have 3 varibales for grouping, such as class, area, school, so I would like to have 2x2x2=8 seperate plots, just like we use the group function in varibility plot.

Re: how to plot an overlay variability chart

Just drag the Class variable to the Page drop area, or the Group By X drop area

Re: how to plot an overlay variability chart

Dragging to the Page area will create the separate graphs, or you can click on the "Dialog" button, and go to a User Entry Dialog box that will let you specify all of your settings, and then select the Class variable for the BY selection
