JMP script formula to calculate the delta of multiple different ranges from X coordinates of a .csv file and display on graph, or in a text box

[#1]

Hi, I have a script that creates the attached graph of some data points and overlays it with an additional line graph. I need to now be able to calculate the delta between the high and low points in multiple different x coordinates. I am able to do the first one since it includes all the x coordinate values, but I am stumped on how to do it for only the x coordinate values in-between the orange calculated lines, as well as only the only the initial curve on both the left and right side inside of the orange line calculations. Than I wanted to display these values on the graph if possible, or in a text box that is displayed when the graph is made. I have included some images that help to explain the 4 different ranges I need to calculate the delta from, as well as included my current script. The orange line may change depending on the data, since it is based off of a value that the user inputs when you run the script. Any assistance is greatly appreciated. Thanks!

So after further testing with my script, it seems that it works perfect (the second time I run it on the data), but not the first time. After the first run it does not calculate and display the delta's, but the second time I run the script it does work...I'm confused. I have attached the cleaned up code, as well as a picture of the no results first run... and a picture of the successful results second run. What am I missing that is not causing my script to work correctly the first time?

framex_value = "";
w = New Window( "Frame size X",// opens a window with a title and this content...

    Border Box( top( 20 ), bottom( 20 ), Left( 20 ), Right( 20 ), // window dressing 
        V List Box( // V and H lists nest to organize the display boxes
            H Center Box( Text Box( "Frame size X" ) ), // a second title, centered
            Spacer Box( size( 1, 20 ) ), // a little vertical space
            H List Box( Text Box( "Frame size X: " ), framex = Number Edit Box( "." ) ), // data entry
            Spacer Box( size( 1, 10 ) ), // a little vertical space
            H Center Box( // center the button
                Button Box( "Create graph", // this script runs when the button is pressed...
                  framex_value = framex << get ;
                   
                    column("X coordinate")<<data type(Numeric)<<Modeling Type(Continuous)<<Format(Best,12);

					// The yMat is static
					yMat = [1, 0.92, 0.92, 1];
					
					// The overall delta
					overallDelta = Col Max( :Normalized ) - Col Min( :Normalized );
					
					
					//The delta between the lines
					withinOrangeDelta = Col Max(
						If( :X coordinate > (76200 - (framex_value / 2)) & :X coordinate < (76200 + (framex_value / 2)),

					);
					
								// Graph Builer and Delta display
								gb = dt << Graph Builder(
								Size( 534, 456 ),
								Show Control Panel( 0 ),
								Variables( X( :X Coordinate ), Y( :Normalized ) ),

							);

							Report( gb )[FrameBox( 1 )] << Add Graphics Script(

								Pen Size( 2 );
								Line( xmat, ymat );
													
													// Add the results to the chart
								Text( Boxed, {75000, .94}, "Overall Delta = " || Char( Format( overallDelta, 7, 4 ) ) );

by default, when JMP creates a variable, like your xMat etc.  the variable will remain until it is changed.  And, if on the first run of your code, the required variable hasn't been created, when you are asking for it in your code, it will not have a value to provide the program, and then some calculations will not be able to be run.  However, if later in the script, the variable is set, it will remain set until deleted of changed.  Therefore, when you run the script for a second time, and the code gets to the point where in the first run of the script, it could not find the required variable, this time it will find it, because it was set at a later time in the code during the last run of the script.

I found a possible place where this could have happened.  You were setting the variable dt after activities on the data table were being done.  I moved the line of code further up in the script, so that may get the code to work on a first run.  I also placed a "Clear Symbols()" as the first line of the script.  This will clear out all variables in the code as the script begins.  This will ensure that the variable values referenced will have to have been created in this run of the code, since all of the values from the last run have been erased.  Try the code and see if it works.

Thanks @txnelson. I was able to get this figured out and it is working perfect. I found that I needed to put { } around the xy coordinates for the text to show up in the graph. I really appreciate all your knowledge and assistance with my script!

Perfect, thanks @txnelson. These 2 changes did the trick. It is working perfect now. Thanks again for all the help with this!
