TickValueFormat is not working in GTL with no Lattice

Please ignore the gray square in legend, this can be fixed by 'legendItem'.

This is the picture I wanted. The percent of the car produced have been displayed by categories ( the cars' Type and DriveTrain).

But, when I generated the figure by statgraph 'barchart_with_no_lattice', the tick values of y axis were not displayed as expected. The code is as follows:

About the format of 'cateparam.', please refer to the last part.

proc template;
  define statgraph barchart_with_no_lattice;
    begingraph /border=false;

      discreteattrmap name='colors' / ignorecase=true;
        value "Asia"     / lineattrs=(color=&color1.)  fillattrs=(color=&color1.);
        value "Europe"   / lineattrs=(color=&color2.)  fillattrs=(color=&color2.);
        value "USA"      / lineattrs=(color=&color3.)  fillattrs=(color=&color3.);
      enddiscreteattrmap;
      discreteattrvar attrvar=barcolors var=origin attrmap='colors';

      layout overlay /
        yaxisopts = (display=(ticks tickvalues) 
          linearopts=(tickvaluesequence=(start=&xmin. end=&xmax. increment=1) tickvalueformat=cateparam.))
        xaxisopts = (display=(ticks tickvalues)
          linearopts=(viewmax=100 viewmin=0 tickvaluesequence=(start=0 end=100 increment=10)));

        barchart category=paramn response=percent / name='origin' group=barcolors orient=horizontal grouporder=data
          groupdisplay=stack display=(fill);
        discretelegend 'origin';
      endlayout;
    endgraph;
  end;

The figure generated by 'barchart_with_no_lattice':

Please ignore the gray square in legend, this can be fixed by 'legendItem'.

And, I used the 'lattice' to display the text for a temporary solution, left and right. In the left figure, I wantted to display the text that should be showed in tick values. Suddendly, I found the TickValueFormat was working as expected, so the width of left figure was set to 0, finally the first figure above was generated. the code I used as follows:

proc template;
  define statgraph barchart_with_lattice;
    begingraph /border=false;

      discreteattrmap name='colors' / ignorecase=true;
        value "Asia"     / lineattrs=(color=&color1.)  fillattrs=(color=&color1.);
        value "Europe"   / lineattrs=(color=&color2.)  fillattrs=(color=&color2.);
        value "USA"      / lineattrs=(color=&color3.)  fillattrs=(color=&color3.);
      enddiscreteattrmap;
      discreteattrvar attrvar=barcolors var=origin attrmap='colors';

      layout lattice / columns=2  columnweights=(0 1.0) rowdatarange=union;

        layout overlay / walldisplay=none yaxisopts=(display=none) xaxisopts=(display=none);
          scatterplot y=paramn x=param /markercharacterposition=right;
        endlayout;

        layout overlay /
          yaxisopts=(display=(ticks tickvalues) 
            linearopts=(tickvaluesequence=(start=&xmin. end=&xmax. increment=1) tickvalueformat=cateparam.))
          xaxisopts=(display=(ticks tickvalues)
            linearopts=(viewmax=100 viewmin=0 tickvaluesequence=(start=0 end=100 increment=10)));

          barchart category=paramn response=percent / name='origin' group=barcolors orient=horizontal grouporder=data
            groupdisplay=stack display=(fill);
          discretelegend 'origin';

Did I miss something in 'barchart_with_no_lattice'? Why did not the TickValueFormat work?

Re: TickValueFormat is not working in GTL with no Lattice

I don't think the base of bar charts can be considered "linear" as they are categorical. So I'm not surprised that LINEAROPTS applied to that axis misbehave. Kind of says so right in the syntax:

barchart category=<variable name>

The variable is categorical.

Re: TickValueFormat is not working in GTL with no Lattice

DanH_sas — Wed, 30 Oct 2024 17:34:40 GMT

@ballardw is correct that the bar chart category axis is discrete by default, causing the TickValueFormat in the LINEAROPTS to be ignored. However, bar chart DO support linear category axes. So, if you set the Y axis explicitly to be TYPE=LINEAR, your format should be honored. Let us know if that works for you.

Thanks for your reply. This make it sense about 'category'.

Eric_Lee — Wed, 30 Oct 2024 23:17:39 GMT

It works as expected. Thank you very much. Also, I got the idea about the usage of 'category'. Lots of help.
