Flot Charts, default x-axis from two days ago until now (last 48 hours)

Question

I have an app that features a chart whose dados from the database, where the date columns store a Unix timestamp, the data is received as a JSON. This graph works well but I would like the X axis to appear only the last 48 hours, but in zoomout/drag (Navigate plugin) we can see more behind. I would just like the chart to show only the last 48 hours, but if you do zoomout or drag you can see the previous ones.

Here is my Jsfiddle, works well just like to add functionality and do not know how.

Code:

        var maxY1 = 2700 + 200;

        var invoicesDone = JSON.parse('{"1":[2820,"1452786357","Lexy Panterra"],"3":[1200,"1452786372","Lexy Panterra"],"9":[139.98,"1452862028","Lexy Panterra"],"12":[139.98,"1452862796","Lexy Panterra"],"15":[75,"1452881987","Lexy Panterra"],"17":[69.99,"1452893153","Lexy Panterra"]}');
        var invoicesPending = JSON.parse('{"2":[90,"1452786365","Lexy Panterra"],"4":[650,"1452786991","Lexy Panterra"],"5":[75,"1452853490","Lexy Panterra"],"6":[120,"1452861281","Lexy Panterra"],"7":[18.1,"1452861333","Lexy Panterra"],"8":[75,"1452861815","Lexy Panterra"],"10":[18.1,"1452862035","Lexy Panterra"],"11":[69.99,"1452862576","Lexy Panterra"],"13":[69.99,"1452871025","Lexy Panterra"],"14":[69.99,"1452873140","Lexy Panterra"],"16":[680,"1452882012","Lexy Panterra"],"18":[720,"1452937569","Miguel Fraz\u00e3o"]}');

        var idInvoicesDone = [];
        var invoicesDoneData = [];
        for (var key in invoicesDone) {
            idInvoicesDone.push({'id': key, 'name': invoicesDone[key][2]});
            invoicesDoneData.push([invoicesDone[key][1]*1000, invoicesDone[key][0]]);
        }

        var idInvoicesPending = [];
        var invoicesPendingData = [];
        for (var key in invoicesPending) {
            idInvoicesPending.push({'id': key, 'name': invoicesPending[key][2]});
            invoicesPendingData.push([invoicesPending[key][1]*1000, invoicesPending[key][0]]);
        }

        /*var 2daysAgo = new Date(1313564400000).getDate();
        alert(2daysAgo);*/

        var data1 = [
            {
                label:"Faturas despachadas",
                data: invoicesDoneData,

Answer 1

To present only the last two days, but to be able to see the previous ones if you want:

JS:

var minX = new Date();
minX.setDate(minX.getDate() - 2);

...
   xaxis: {
   mode: 'time', timeformat: '%d/%m/%y',
   tickLength: 5,
   min: minX,
},
...
