Dataset not updating automatically

Question

Hello,
I have a graph that is dynamic.  I already have a variable set up and also a dataset.  This file is saved.
Basically, I am trying to write some code that will open the document, import the variable file (with the new data from the xml file) and then update the graph.
Using the code below, the file opens and also the import of the variables is succesful.  However, the graph is not updating automatically.  I need to actually select the value from the dropdown in the variables window.  Can anyone please tell me what I am doing wrong.
   // Open the file and import the datasets and variables from xml file
  var docRef = open(new File(aiChartFilePath));
   alert("Importing the datasets.");
   docRef.importVariables(new File(xmlFilePath));
var ds1 = docRef.dataSets.getByName("Chart1Variable");
alert(ds1); //this gives the "DataSet Chart1Variable"
docRef.activeDataset = ds1;
ds1.display();
redraw();
rs = "OK";
Thanks in advance for your help.

this should work just fine ... put 2 datasets in the same file:

Javascript code:
var DBHelper = {
                mainFs: null,
                loadFile: function(fileOrFilename, isAI) {
                            var _fl = (fileOrFilename instanceof "File") ? fileOrFilename : new File(fileOrFilename);
                            if(isAI) { myDoc = app.open(_fl);}                            
                            else {
                                myDoc.importVariables(_fl);
                                this.mainFs = app.activeDocument.path.fullName + "/" + app.activeDocument.name;
                                myDoc.save();
                                myDoc.close();
                                this.loadFile(this.mainFs,true);                               
                displaySet: function(setName) {
                            app.activeDocument.activeDataset = myDoc.dataSets.getByName(setName);
                            app.activeDocument.activeDataset.display();
DBHelper.loadFile("/d/_temp/Capella_Chart_1.ai", true);
DBHelper.loadFile("/d/_temp/variables.xml",false);
DBHelper.displaySet("Capella_1");
