How Do I Change Scale of X-Axis after using Graph Builder in JSL (and graphing approach question)

ToddKeebler — Sun, 11 Jun 2023 11:10:00 GMT

Hi,

I'm writing a script that will work with files that have a variety of columns, so I had to modify an example I found on here which concatenates the Graph Builder call based on the number of columns. Despite being clumsy, it does seem to work, but my issue is that I then want to change the X-axis to log scale, change the limits, etc. I tried a few approaches from the Scripting Index and examples, but none seemed to work.

Would very much appreciate a pointer in the right direction on the axis settings, but if anybody has an idea of how to do initial graphing portion better, that would be great too, thanks!

dt = Current Data Table();
ColNameList = dt << Get Column Names (continuous, string);

//Start with initial graph builder
GraphExpr = "
TestGraph = Graph Builder(
	Size( 534, 456 ),
	Show Control Panel( 0 ),
	
	Variables(";
		
//Add X Entry
GraphExpr = GraphExpr || "
		X( :Name( \!"" || ColNameList[1] || "\!") ),";

//Add the first Y entry
GraphExpr = GraphExpr || "
		Y( :Name( \!"" || ColNameList[2] || "\!") ),";

//Add the second Y entry
For( i = 3, i <= N items (ColNameList), i++,
GraphExpr = GraphExpr || "
		Y( :Name( \!"" || ColNameList[i] || "\!"), Position (1) ),";
);


//Close out Variables section
GraphExpr = GraphExpr || "
	),
	Elements( 
		Line( X, Y( 1 )";

//Build out the lines for all columns
For( i = 2, i <= N items (ColNameList), i++,
	GraphExpr = GraphExpr || ", Y( " || char(i) || " )"
);

GraphExpr = GraphExpr || ", Legend( 1 ) 
		) 
	) 
)";

eval(parse(GraphExpr));

TestGraph << Show Legend (0);

Hi,

This is indeed rather convoluted way to build a Graph Builder expression. You might want to look into the approach of defining your entire GB expression with "placeholders" (gbe = Expr (Graph Builder(...)); use the substitute function to replace your placeholders with column, variables, labels, etc.., and then use the Eval() function to generate the graph (sorry I don't have the time right now to provide more details)

For your specific question, if you assign your Graph Builder expression to a variable (e.g., gb = Graph Builder (...);) you can then use the approach below to update the axis in any way you need:

gb = dt << Graph Builder(
	Show Control Panel( 0 ),
	Variables(
		X( :age, Size( 23 ) ),
		Y( :height, Size( 37 ) ),
		Y( :weight, Position( 1 ), Size( 37 ), Side( "Right" ) )
	),
	Elements( Points( X, Y( 1 ), Legend( 1 ), Jitter( 1 ) ), Points( X, Y( 2 ), Legend( 3 ), Jitter( 1 ) ) )
);
framebox = Report( gb )[framebox( 1 )];
framebox << Y Axis(
	Scale ("Log"),
	Add Ref Line( 61.25, "Solid", "Medium Dark Green" ),
	Show Major Grid( 1 ),
	Show Minor Grid( 1 ),
	Format( "Fixed Dec", 5, 2 ),
	Rotated Labels( "Perpendicular" )
);

I hope this helps.

Best,

All of the messages that change an axis are available in the scripting index entry for AxisBox

What you want to use, is

report(TestGraph)[AxisBox(2)] << scale(log);

Hey Jim, thanks for the quick response on that. That works well. I didn't realize you needed to use report() to reference that graph item, I was just trying to use TestGraph[AxisBox(2)] << scale(log)

Thanks,

Todd

Is there a description how this can be done for Gradient Legend settings?

I tried

Report( gb)[Legend Box(1)] << Legend Model( ...

but it didn't work

Hi everyone,

I have kind of similar question, on how to automate the X axis, which is time scale & I would like it to be automatically displayed the data from the last desired period.(n=7) for example.

Much appreciated for your helps.

My script as below:

Hi @jmpfumbler can you post the code using the <JSL> button rather than a picture?

Thanks!
