Add a label to the x axis:

Here are a few examples:

Use title property for one label for the entire axis.

chart.addAxis("x", {
   min: 0, max: 100,
   fontColor: "blue",
   vertical: true,
   fixLower: "major", fixUpper: "major",
   title: "X axis title",
   titleFont: "bold bold bold 12pt Arial,sans-serif",
   titleOrientation: "axis" 
});

For labels on each tick mark on the x axis:

var xAxisLabels = [{text: "Today",value: 1},{text: "-1",value: 2},{text: "-2",value: 3},{text: "-3",value: 4},{text: "-4",value: 5},{text: "-5",value: 6},{text: "-6",value: 7},{text: "WK-1",value: 8},{text: "WK-2",value: 9},{text: "WK-3",value: 10},{text: "WK-4",value: 11}];

chart.addAxis("x", {
 labels: xAxisLabels,
 fontColor: "blue",
     majorTicks:true,
 majorTickStep:1,
    minorTicks:false,
    max: 11
});

Not sure about the database part
