在negativeSeries条形图中添加图例

Question

我想为附加图像的正值和负值添加图例。如何实现此目的？请帮帮我。

我试过代码为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, 
       location : 's', 
       ypadding : 12 
      } 
     }, 
     legend : { 
      show : true, 
      placement : 'outsideGrid',  
      fontFamily : 'OpenSans-Regular', 
      marginTop : '100px', 
      textColor : '#414141', 
      rowSpacing : '14px', 
      border : 'none', 
      background : 'transparent' 
     }, 
     series : [{ 
      label : "Greater", 
      lineWidth : 1, 
      // Use (open) circlular markers. 
      markerOptions : { 
       style : "filledCircle" 
      } 
     }], 
     seriesColors: ["#7DAB0B"], 
     negativeSeriesColors: ["#D99F03"], 
     axes:{ 
      yaxis:{ 
       renderer: $.jqplot.LinearAxisRenderer, 
       fontFamily : 'OpenSans-Regular', 
       label : "kWh", 
        textColor : '#414141', 
        tickOptions : { 
         show : true, 
         fontFamily : 'OpenSans-Regular', 
         textColor : '#414141', 
         fontSize : '10pt' 
        } 
      }, 
      xaxis:{   
       label : "Date", 
       renderer : $.jqplot.CategoryAxisRenderer, 
       labelRenderer : $.jqplot.CanvasAxisLabelRenderer, 
       tickRenderer : $.jqplot.CanvasAxisTickRenderer, 
       //renderer: $.jqplot.CategoryAxisRenderer, 
       fontFamily : 'OpenSans-Regular', 
        textColor : '#414141', 
        tickOptions : { 
         angle : -60, 
         show : true, 
         fontFamily : 'OpenSans-Regular', 
         textColor : '#414141', 
         fontSize : '10pt' 
        } 
      }, 
     }, 
     grid : { 
       background : 'transparent', 
       gridLineColor : '#c5c5c5' 
      } 
    }; 
    try {  
      var plotBarChart = $.jqplot("chart1", [xSeries], barChartOptions);  
     } catch (e) { 
      // alert(e); 
     }

确保您的代码如下this格式。

也一定要包括jquery.jqplot.css

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

或者将以下代码复制到您的css文件：

//jquery.jqplot.css
