Spline Fit Line Legend

[#1]

Hi all,

I am trying to create bivariate plots with a fit spline. However, I am trying to get the line legends but with no success. How can I get and save the line legend? Please help

Here's my function

bivplot_mrw = Function({ ycol }, {plot},
						
						biv = Bivariate( Y( Column(dt, ycol) ), X( Column( dt, mrwname ) ), Group By( Column( dt, grpname2 ) ), 
										 Fit Spline( 1000 ) );			
												
						rbiv = biv << report << Show Points( 0 );
						
						ylist = {};	
							
						For(g2 = 1, g2 <= Nitems(grplist2[1]), g2++,
							Try(
							curvename = rbiv[Outline Box( g2 + 1 )] << Get Title;
								
							//Compute max and min per spline fit line to get y-axis max and min
							current_row = storows2[ Contains( stolist2, grplist2[3][g2] ) ];	//Get the stolist rows for grplist2[g2]
							current_row << Intersect( grprows[ Contains( grplist, grplist2[2][g2] ) ]);
							current_row = Matrix( current_row << Get Keys );
							xin = Column( dt, mrwname)[current_row];
							yin = Column( dt, ycol)[current_row];
							Try(ypred = Spline Eval( xin, Spline Coef( xin, yin, 1000 ) ));
							ylist = Concat(ylist, As List(ypred));
								
							//Adjust also the line style
							If(
								Contains( curvename, linestyle["ddd"] ),
									biv << (Curve[g2] << Line Style( DashDotDot )),
								Contains( curvename, linestyle["dash"] ),
									biv << (Curve[g2] << Line Style( Dashed ))
								);
							));	
													
						Try( paxis = axiscalc( Min(ylist), Max(ylist) ), Show("axiscalc error for "||ycol) );
						Try( xaxis = axiscalc( mrwmin, mrwmax ), Show("axiscalc error for MRW") );
						
						rbiv[Frame Box( 1 )] << {Frame Size( 205, 164 ), Marker Size( 1 ), Line Width Scale( 2 )};
							
						Try( rbiv[Axis Box( 1 )] << Max( paxis["Max"] ) << Min( paxis["Min"] ) << Inc( paxis["Inc"] ) << Minor Ticks( paxis["Ntick"] ) );
						Try( rbiv[Axis Box( 2 )] << Max( xaxis["Max"] ) << Min( xaxis["Min"] ) << Inc( xaxis["Inc"] ) << Minor Ticks( xaxis["Ntick"] ) );
					
						rbiv[Axis Box( 1 )] << Format( "Best", 12 ) << Tick Font( style( 1 ), size( 9 ) )
											<< Show Major Grid( 1 ) << Show Minor Grid( 1 ) << Show Minor Ticks( 1 );
							
						rbiv[Axis Box( 2 )] << Format( "Best", 12 ) << Tick Font( style( 1 ), size( 9 ) )
											<< Show Major Grid( 1 ) << Show Minor Grid( 1 ) << Show Minor Ticks( 1 );
							
						rbiv[Text Edit Box( 1 )] << Set Font Size( 10 ) <<	Set Font Style( "Bold" );
						rbiv[Text Edit Box( 2 )] << Set Font Size( 10 ) <<	Set Font Style( "Bold" );
						(rbiv << xpath( "//OutlineBox" )) << Close;
						rbiv[Outline Box( 1 )] << Set Title( ycol );
						rbiv[Border Box( 2 )] << Delete Box;
							
						rbiv[Outline Box( 1 )] << Open All Like This;
						
					);

I'm not quite sure what you mean by 'get the line legends'. Using the example below, could you be a little more specific about what information you want to get from the report, please?

Hi ian_jmp, I wanted to save/get the line legend as an image so I can use it on other slides in my powerpoint

[#4 · Accepted solution]

Does this help?

NamesDefaultToHere(1);

dt = Open("$SAMPLE_DATA/Big Class.jmp");

biv = dt << Bivariate(
				Y( :weight ),
				X( :height ),
				Show Points( 0 ),
				Fit Where( :sex == "F", Fit Spline( 1000, {Line Color( {212, 73, 88} )} ) ),
				Fit Where( :sex == "M", Fit Spline( 1000, {Line Color( {66, 112, 221} )} ) ),
				SendToReport(
					Dispatch(
						{},
						"Bivar Plot",
						FrameBox,
						{Grid Line Order( 1 ), Reference Line Order( 2 )}
					)
				)
			);

bivRep = Report(biv);
pb2Pic = bivRep[PictureBox(2)] << getPicture(Scale(1.5));
nw = New Window("Example", pb2Pic);

Like @ian_jmp, I am not sure what you are asking either, but here is a simple example to illustrate the syntax to access the commands in the red triangle menu for each fit:

Names Default to Here( 1 );

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

biv = dt << Bivariate(
	Y( :weight ),
	X( :height ),
	Fit Spline( 10 )
);

biv << (Curve[1] << Line Color( "Green" ) );

HI  markbailey, I just need to have the line legends saved as an image so that I can use it on several slides in my powerpoint.
