Interfacing sample application "Launcher with Report" to a graph from graphbuilder.

dfshort

I'm new to JSL and I suspect I'm going about this in the wrong way. Pointers and ideas would be welcome.

I have a data table that contains several versions of Z scores from slightly different models.

                    Z score from Model A     Z Score from Model B....Z Score from model X

I'm trying to build a data visualization application where the client would pick a pair of these z values and a critical value.

The resultant interactive graph would then be an XY chart of the Z values and a horizontal line and a vertical line, both at the chosen critical value.

Hopefully the client can then mouse around the chart and locate individuals with dramatically different Z values.

I constructed a graph in graph builder that does what I want for a pair of variables.

I've modified the sample application Launcher with Report to return an X Value, a Y Value and a Critical number and have managed to pass these values into the code from graph builder.

OnModuleLoad({items},

    yval = items[1];

    xval = items[2];

    critical = items[3];

);

By changing x variable to xval (and the same thing for the y axis) I can make the sample application change axis. There is sample code at the end of the post.

I'm running into two problems.

#1. I can't seem to suppress the column dialog that autostarts when I use xval/yval. (If I could get the column dialog to pass a critical value....I suppose I could work with that.)

#2 I can't seem to locate a suitable way to modify the dispatch lines so the vertical and horizontal lines appear when I change the X, Y values from what they where when I created the graph in graph builder.

Am I just way up the wrong tree here?

Thanks in advance for any replies.

			Report1 = Platform(
				DataTable1,
				Graph Builder(
					Show Control Panel( 0 ),
					Variables( X( Eval( xval ) ), Y( Eval( yval ) ) ),
					Elements( Points( X, Y, Legend( 1 ), Jitter( 1 ) ) ),
					SendToReport(
						Dispatch(
							{},
							"Z Value From A",
							ScaleBox,
							{Add Ref Line(
								Eval( critical ),
								Solid,
								"Red",
								"",
								2
							)}
						),
						Dispatch(
							{},
							"Z Value from D",
							ScaleBox,
							{Add Ref Line(
								Eval( critical ),
								Solid,
								"Red",
								"",
								2
							)}
						)
					)
				)
			)
		),

Thank you

I see - it's definitely an issue when the Dispatch() commands refer to one of the values that has been parameterized.  This may be a case where scripting the Ref Lines is easier than trying to use the Dispatch.  After the objects have been created (after thisModuleInstance << Create Objects in the script for Module1), you would include something like:

Report1[AxisBox(1)] << Add Ref Line( critical, "Solid", "Black", "", 2 );

The default behavior of App Builder is to use the Current Data Table for any boxes or reports that require a table.  To change this, select the Data Table in the Object Tree, and change the "Location" property.  A value of "Prompt" will always prompt you to select (or open) the table.  Note that the Location property only applies at run-time.  You still need to have a path to a data table so that App Builder can open the table at edit time.

There are on-line classes available for help in learning JSL.  Next month there is a Live Web Introduction to JSL that may be helpful.  There are other classes as well, including one for Application development using Application Builder, but that is not available again until September.  You can also just purchase the course notes by themselves.  Two books of interest are Jump into JMP Scripting and JSL Companion: Applications of the JMP Scripting Language.

Hope that helps!
