Please guide me to draw graph using jqplot

Answer 1

First of all...
To recreate the problem on CodePen, I had to use libraries from cdnjs.com because nothing was going on except red lines in console.

So maybe you should use these too(!).
Notice that I also used lastest jQuery and jQuery-UI.

Only then, I saw a graph background appear... But without any line or anything.

So, looking at some examples here , I found that you are absolutely wrong on the way to provide data to the beast.

Your data input is :

$.jqplot ('test_chart',[[10,20,12]],

And what's needed is:

var arr = [['2016-10-01',10],['2016-10-02',20],['2016-10-03',12]];

$.jqplot ('test_chart',[arr],

OR (If you really don't like to define data in an array first...):

$.jqplot ('test_chart',[[['2016-10-01',10],['2016-10-02',20],['2016-10-03',12]]],

Do you notice the bracket amount ?
Moreover, do you notice that each X-axis value is associated to a Y-axis value in this array?

That was your main problem.
Plus the odd cdns and the missing $(document).ready({ wrapper.

So now, have a look at your working graph in this codePen
And have fun ploting graphs...
;)
