Question

我想为正值和负值添加图例，如图像附加。我如何实现这一目标？请帮我。

我的尝试代码为FIDDLE

 xSeries = [["a", -1], ["b", 2], ["c", -3], ["d", 5]];
        var barChartOptions = {
        seriesDefaults: {
            renderer: $.jqplot.BarRenderer,
            rendererOptions: {
                barDirection: 'vertical',
                barWidth:10,
                varyBarColor: true,
            },
            fillToZero: true,
            fillAxis: 'x',
            pointLabels: {
               // show: true
            },
            pointLabels : {
                show : true,
                hideZeros : true,

确保您的代码遵循this格式。

还要确保包含jquery.jqplot.css

包含它：<script src="https://bitbucket.org/cleonello/jqplot/raw/e8af8a37f0f14ea1e8c630ecfe6f1b1933794036/src/jquery.jqplot.css"></script>

或将以下代码复制到css文件中：

//jquery.jqplot.css
    /*rules for the plot target div.  These will be cascaded down to all plot elements         according to css rules*/
     .jqplot-target {
