When not using graph builder, it's easy to right click on graph and select row legend, select column, markers, alphanumeric. But I don't see how to do it with graph builder?
I can use mark by column in the datatable to mark as alphanumeric; but when this is graphed in graph builder, although the symbols in the graph are maintained as alphanumeric, the legend doesn't show the alphanumeric symbol, just the dot.
Starting with JMP 12.0, Graph Builder will show the table's row markers in the legend if they are consistent with the legend's variable. That is, if you use the alphanumeric theme in the Mark By Column dialog and use the same variable in the Overlay role in Graph Builder, it will use those markers in the graph and show them in the legend.
I apologize for some Friday afternoon frivolity, but if you've ever asked yourself "How many markers does JMP actually have?", you can test your patience and discriminatory capabilities with this script:
Markers_dt = New Table( "Marker Codes",
Add Rows( 5000000 ),
New Column( "Marker Number", Numeric, Formula( Row() ) ) );
For( i = 1, i <= N Row( Markers_dt ), i++,
Marker Of( Row State( i ) ) = i );
After all, one may not want to constrain oneself with a Western alphanumeric marker theme!
