Threshold corrupts bar charts

[GoogleCodeExporter]

If I apply a threshold to a dataset with bars: {show:true} the data
displays incorrectly - bars extend to the top of the chart, and if lines
are set to show, they extend from the left side of the chart. Appears data
is being corrupted by the application of a threshold to a bar chart.

If I change bars: {show:false} everything appears correctly.

Code that's producing this:

function plotWithOptions(t) {
    $.plot($("#placeholder"), [
        { label: "Variance",
            data:variance,
            color: "rgb(240,240,240)",
            yaxis:2,
            bars: { show: true, fill:true, lineWidth:10 },
            lines: {show:false},
            points: {show:false},
            threshold: { below: 0, color: "rgb(200, 20, 30)" }

        },
        { label: "data1", data: data1},
        { label: "data2", data:data2}
        ],
           {series: {lines: { show: true },points: { show: true }},
        grid: { hoverable: true, clickable: true },
        xaxis: { mode: "time"},
        yaxis: {min:0},
        y2axis: {}
           }
    );
    }
plotWithOptions(0);

The  attached file should fix the threshold with barcharts. I did not get the 
normal threshold to work, so I tried this one. This one did work, but created 
threshold datapoints, which I wanted removed if the dataseries is of type bars.

I did not create this patch, but I fixed it for my barcharts. I was posted here 
on some other issue/enhancement.

I suspect the issue described is the same that I've come across. It seems that 
when using the threshold plugin it corrupts the datapoint set by not respecting 
the datapoint format.

I managed to hunt down the issue to two little lines and have provided a diff. 
This fixed it for me when using stepped lines with fills and bar charts.

Thanks for the patch. I changed it to start from m = 2, and it seems to be 
working fine.
