If you like to store data in labelled 2D, rather than in multiple 1D waves, this snippet might be useful.
Simply use the dimlabels to display specific rows or columns against each other, either display or append to top graph.
function mPlot(wave w, string yL, string xL, int dim [, int a])
// displays rows or columns from a 2D wave w, depending on dim (0 or 1), as x-y plot
// x and y are defined by dimension labels and passed as strings yL and xL
// optional variable a: if specified as non-zero integer, data will be added to top graph
// a=0 is the same as omitting a
if (FindDimlabel(w,dim,yL) == -2 || FindDimLabel(w,dim,xL) == -2)
print "DimLabel(s) not found"
return -2
endif
// make sure a(ppend) is assigned
a = !ParamIsDefault(a) && a !=0 ? 1 : 0
if(a==0)
if(dim==0)
Display/W=(483,45,1125,561) w[%$yL][] vs w[%$xL][]
else
Display/W=(483,45,1125,561) w[][%$yL] vs w[][%$xL]
endif
// do some preferred graph formatting and set axes labels
ModifyGraph tick=2,mirror=1,minor=1,btLen=4,stLen=2
ModifyGraph margin(left)=70,margin(bottom)=70
Label Bottom "\\Z22"+xL
Label left "\\Z22"+yL
SetAxis/A/N=1
Legend/C/N=text1/S=3/A=MC
else
if(dim==0)
AppendToGraph w[%$yL][] vs w[%$xL][]
else
AppendToGraph w[][%$yL] vs w[][%$xL]
endif
endif
return 1
end
// displays rows or columns from a 2D wave w, depending on dim (0 or 1), as x-y plot
// x and y are defined by dimension labels and passed as strings yL and xL
// optional variable a: if specified as non-zero integer, data will be added to top graph
// a=0 is the same as omitting a
if (FindDimlabel(w,dim,yL) == -2 || FindDimLabel(w,dim,xL) == -2)
print "DimLabel(s) not found"
return -2
endif
// make sure a(ppend) is assigned
a = !ParamIsDefault(a) && a !=0 ? 1 : 0
if(a==0)
if(dim==0)
Display/W=(483,45,1125,561) w[%$yL][] vs w[%$xL][]

endif
endif
return 1

Hmm, makes me think that an option for '2-D columns by dim label' could be added to the XY browser project... I don't have any immediate use for such a feature, but if someone is interested they should let me know.

You can enter dimension labels as subranges in the New Graph dialog. If you use the more complex mode (click the More Choices button to display the holding list below the wave lists) you can Add a trace to the holding list, then pop up the menu on the desired dimension and you will get a menu of dimension labels.

John, I should have said that the snippet is meant as a shortcut to the above, I just need fewer characters on the command line ;-)
