scatterplot with double legend

[Kylie]

Hi all,

I wish to draw a scatterplot with markers defined by two categorical variables -
one for the colour and the second for the shape.

I have data such as the following:
data list free / group item x y.
begin data.
1 1 856 385
1 2 1142 824
1 3 1064 497
1 4 1036 543
1 5 547 796
1 6 576 507
1 7 1050 488
2 1 1688 673
2 2 1093 367
2 3 1050 545
2 4 1043 740
2 5 775 293
2 6 1621 495
2 7 869 403
3 1 1008 488
3 2 570 338
3 3 656 756
3 4 1485 794
3 5 1394 322
3 6 1345 540
3 7 1159 619
end data.

I'm trying to generate a scatterplot of x vs y, with colours set according to
the 'group' variable, and the marker shape set according to the 'items'
variable. I don't know if it needs the 'group' and 'item' variables as I've got
them, or a new variable for the combination (ie, values 1-21)? I don't really
know enough about GPL to know where to start with this one.

Any suggestions would be appreciated.

Thanks,
Kylie.

Note that x and y need a scale measurement level, here set in GGRAPH but alternatively in the Data Editor.

You can generate most of this from the Chart Builder.  The extra part is for item, which is used in the ELEMENT command to set the shape.

Use chart builder to generate the syntax for just the group and then add to
the syntax the necessary stuff for item. Here's the syntax:

variable level x y (scale).
* Chart Builder.
GGRAPH
  /GRAPHDATASET NAME="graphdataset" VARIABLES=x y group item
MISSING=LISTWISE REPORTMISSING=NO
  /GRAPHSPEC SOURCE=INLINE.
BEGIN GPL
  SOURCE: s=userSource(id("graphdataset"))
  DATA: x=col(source(s), name("x"))
  DATA: y=col(source(s), name("y"))
  DATA: group=col(source(s), name("group"), unit.category())
  DATA: item=col(source(s), name("item"), unit.category())
  GUIDE: axis(dim(1), label("x"))
  GUIDE: axis(dim(2), label("y"))
  GUIDE: legend(aesthetic(aesthetic.color.exterior), label("group"))
  GUIDE: legend(aesthetic(aesthetic.shape), label("item"))
  ELEMENT: point(position(x*y), color.exterior(group), shape(item))
END GPL.

Additions:
Add item to the VARIABLES keyword on the GRAPHDATASET subcommand.
Add a DATA statement to define the item as a categorical variable.
Add a GUIDE statement to define the label for item  legend.
Add the shape(item) function to the ELEMENT statement.

Note--
I personally prefer the color function which sets color for both the border
and the fill as opposed to the color.exterior function which sets color only
for the border and leaves the marker unfilled. The designer of the UI was
being cautious and felt that solid fills would obscure overlying points.

p.s. You can generate this chart entirely from the user interface by using GraphBoard (on the Graphics menu).  On the detailed tab you can set both the shape and color variables (as well as size and transparency variables).

1.       Yes. Try Graphboard instead if that’s what you want.

2.       Templates are really fragile—every time I find a bug I report it. The basic problem is that they predate all of the flexibility of the newer procedures to produce charts.

1. Does this mean that it is IMPOSSIBLE to generate 2 categories from chart builder alone? Of course this was possible in the discontinued igraph
2. IF one saves to a .sgt template file, will ALL the specifications get saved?  My experience is that some things, e.g. the setting to  NOT show the regression equation for linear fit lines, do not get saved.  Of course inserting fit lines is only available by editing a generated graph, not in the chart builder dialogue boxes [as was so convenient in igraph]
