How I can set Labels on bars?

[Alexey Shevchenko]

I switch properties:

series: {
    // stack: stack,
    bars: {
        show: bars,
        barWidth: 0.6,
        lineWidth: 0,
        zero: false,
        fill: 0.7,
        align: "center",
        dataLabels: true,
        labelColor: "#000000", // default is black
        labelBold: false, // set to make the label bold
        labelLoc: "center" // top or center
    }
},

Why doesn't it work?

So, to be clear, the bar rendering options do not support rendering labels. Are you asking how you can extend the existing bar rendering options to support the ones you've created in your above snippet? If so, I would imagine you need to create a plugin, and implement the 'drawSeries' (or 'draw'?) method, that could render whatever additional visuals you require. The jquery.flot.errorbars.js plugin is a good example of how you can render additional visuals by adding options to the existing set.

This plugin exists, though it was designed for an older version of Flot.
