Shifting the position of bars in a horizontal bar chart in Flot

I have 2 charts that are generated in Flot. Sample charts

I would like to move the bar in the chart with 1 bar away from the x-axis. I would like it to have gaps similar to the graph with 10 bars. For example, is there a simpler way of specifying that I want the bar to be 10 pixels away from the y-axis?

This is the code that generates these charts:

<!DOCTYPE html>
<html>
<head>
    <script type="text/javascript" language="javascript" src="./flot/jquery-1.8.2.js"></script>
    <script type="text/javascript" language="javascript" src="./flot/jquery.flot.js"></script>
    <script type="text/javascript" language="javascript" src="./flot/jquery.flot.categories.js"></script>
    <style type="text/css">
        .graph-container.store-container {
            height: 180px !important;
        }
        .graph-container.operator-container {
            height: 450px !important;
        }

        #top-stores-plot-numbers {
            height: 70px !important;
        }
        #top-operators-plot-numbers {
            height: 340px !important;
        }
    </style>

    <script type="text/javascript">
        $(function() {
            var plotOptions = {
                legend: {
                    show: false
                },
                series: {
                    bars: {
                        show: true,
                        barWidth: 0.7,
                        align: "center",
                        horizontal: true
                    }
                },
                yaxis: {
                    mode: "categories",
                    tickLength: 2,
                    axisMargin: 10,

                xaxis: {

                    min: 0,
                    ticks: 2
                }
            };

            var sn_data = [

You need to change the autoscaleMargin between graphs, not the max for the y-axis.

When you have 1 bar, set it to 0.5. When you have 10 bars, set it to 0.05. Take out any mention of yaxis.max and that should do it.

I changed your yaxis object to look like this in plotOptions:

            yaxis: {
                mode: "categories",
                tickLength: 2,
                autoscaleMargin: 0.5
            }

That's all you need for the 1 bar graph.

Before calling $.plot for the 2nd graph, change the autoscaleMargin like so:

            on_options["yaxis"]["autoscaleMargin"] = 0.05;

That's it, see it in action (minus the categories plugin): http://jsfiddle.net/ryleyb/tVmTt/
