javascript - Getting the last value of an Array and showing it under X axis

Question

var NewdateData[] = [1,2,3,4,5,6,7,8,9,1,2,1,23,45,56]

This NewdateData is dynamically filled from database depending upon the selection made from the user interface.

I am using this NewdateData for displaying under the X axis Charts.

The issue I am facing is that, the values are not taken till the end , I want to have the last value to have under the X axis Labels.

xaxis: {tickFormatter: function(n)
{
    var k = Math.round(n);
    return NewdateData[k]; 
}

I am using flotr.

You can get the last value of an array with:

NewdateData[NewdateData.length-1];
