Flot not displaying x axis labels correctly

Question

I have to display a graph with date on the X axis and Amt on the Y axis. There will be 8 lines (series) each with n months data. When I plot the graph I am sending in 6 months data for sure.( one line's data is shown below)

[1251701950000, 34.50553] [1254294030000, 27.014463] [1256972350000, 26.7805] [1259567970000, 33.08871] [1262246430000, 51.987762] [1264924750000, 56.868233]

However the graph shows up like this http://twitpic.com/1gbb7m

The first months label is missing and last month is not aligned correctly, my flot js code is as follows

$.plot($("#lgdGraphTab"),graphData, 
            { 
                xaxis: { 
                        mode: "time",  
                        timeformat: "%b-%y",
                        monthNames: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],
                        minTickSize: [1, "month"]
                        },
                yaxis : {
                    tickSize: 5 
                },

                series: {
                         lines: { show: true , shadowSize:0},
                         points: { show: true }
                },
                legend:{    
                    container: $('#legendArea'),
                    noColumns:8
                },
                clickable: true,
                hoverable: true


});

Answer 1

All of the timestamps in your data hold the last day of each month rather than the 1st. I believe this is the cause of your problem.
