 #myTop10_2024    What inspired this wish list request?  
 For Line Graphs in Graph Builder, there is a cool feature row order.  If it's selected, the line doesn't connect data points from left to right in the graph - but along the order in which they appear in the data table. 
    
   
 Instead of this graph: 
    
 the user gets this graph: 
    
 Much better ... 
   
 But unfortunately, there are those nasty jumps "back" to the next curve. 
 Of course, for simple graphs, you can use a column (here "Station") as an overlay to produce 3 separate curves, without the zigzag.  But already with slightly more complicated graphs like this one here: Graph Builder. Combine Smoother and Line - how? the user reaches the limits of current Graph Builder (v17, v18). 
   
   
   
 What is the improvement you would like to see?  
   
 
  With sorted data in the data table, a step from right to left indicates a new curve.  So, with row order enabled, there could be an additional option to draw lines  "only left -> right".  If this option is enabled, line for steps from higher to lower values will disappear -> the jump back-lines are gone : )         
 Fallback:  Rows with missing y value could be used to add a break in line graphs (even somewhere in the center of the graph - cool, right?)  ... if there was an option: *)      
   
 
 
 Why is this idea important?  
 a tiny change of the program - a  tremendous improvement for the users: 
    
      
  dt =Open( "$SAMPLE_DATA/Functional Data/Weekly Weather Data.jmp" );
dt << New Column( "group",Character,"Nominal",Formula( Substr( :STATION, 8, 1 ) ));
Graph Builder(
	Size( 523, 407 ),
	Summary Statistic( "Median" ),
	Graph Spacing( 4 ),
	Variables( X( :DATE ), Y( :TAVG ), Overlay( :group ), Color( :group ) ),
	Elements( Line( X, Y, Legend( 31 ), Row order( 1 ) ) ),
	Local Data Filter(
		Add Filter(
			columns( :STATION ),
			Where( :STATION == {"USW00003195", "USW00003868", "USW00003949"} ),
			Display( :STATION, N Items( 15 ) )
		)
	)
)
