In this example, when we defined the data set templates, we gave each of them a name (DS1, DS2, DS3), and when we added our data sets, we gave each of them a name as well (SERVER1, SERVER2, SERVER3). We were then able to link the date set template with the data set via .LAYER LINK DATASET TM, passing it the specific names we wanted linked. If we wanted to render this chart with a different set of data, all we have to do is create 3 new data sets, relink them using .LAYER LINK DATASET TM, and then render the chart again. Notice when we called .XY ADD BAR LAYER, we passed the OFF parameter to suppress the automatic creation and linking of data groups, data set templates and data sets. Since we are managing this ourselves, we did not want the routine to do it for us. Also notice the technique of passing an empty field to .XY ADD BAR LAYER. We wanted to pass the first and third parameters, so we had to have a dummy field to pass as the second parameter (--- TEMP 1 in this case). |
