Support for discontinuous index of array

[GoogleCodeExporter]

ex1) array index: 1,2,3,4,5,6,7,8,,,
graph is not broken.

ex2) array index: 1,2,3,5,6,7,8,,,,
graph is broken.

If we delete some elements of array, graph is broken. So I fixed it in the flot 
version 0.7.

Please see my attached files.

example code of the zooming.html

var startData = getData(0, 3 * Math.PI);

delete startData[0]['data'][11];
delete startData[0]['data'][12];
delete startData[0]['data'][13];

var plot = $.plot($("#placeholder"), startData, options);

The problem is that you're using JavaScript's 'delete', which doesn't actually 
remove the array element; it just sets it to null.  Flot, by design, treats 
nulls as gaps in the line.

So this isn't a bug in Flot; you should use 'splice' instead of delete, so the 
unwanted elements are actually removed.
