我正在使用一些基于jqplot的代码，它绘制条形图并允许通过点击图例名称来切换图表系列，请参阅下面的功能代码。
是否可以通过一个图例来控制各种图表系列？如果是这样，怎么样？
function drawBarchart(name,ticks,labels,s11,s12,s21,s22){
var plot1 = $.jqplot(name, [s11,s12,s21,s22], { //'chart1' -> define wrapper <div id='chart1'> </div>
// The "seriesDefaults" option is an options object that will
// be applied to all series in the chart.
grid:{borderColor:'transparent',shadow:false,drawBorder:false,shadowColor:'transparent'},
seriesDefaults:{renderer:$.jqplot.BarRenderer, //choose bar chart
rendererOptions: {fillToZero: true},
pointLabels: { show: true, location: 'e', edgeTolerance: -15 } //adds values+labels to bars
},//seriesDefaults
// Custom labels for the series are specified with the "label"
// option on the series option. Here a series option object
// is specified for each series.
series:[ //define labels
{label:labels[0], shadow: false},
{label:labels[1], shadow: false},
{label:labels[2], shadow: false},
],//series
// Show the legend and put it outside the grid, but inside the
// plot container, shrinking the grid to accomodate the legend.
// A value of "outside" would not shrink the grid and allow
// the legend to overflow the container.
legend: {
show: true,
placement: 'outsideGrid',
renderer: $.jqplot.EnhancedLegendRenderer //enables toggling data and legends
},//legend
axes: {
// Use a category axis on the x axis and use our custom ticks.
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
ticks: ticks,
tickOptions: {showGridline: false}
},//xaxis
// Pad the y axis just a little so bars can get close to, but
// not touch, the grid boundaries. 1.2 is the default padding.
yaxis: {
showTicks:false,
label: 'axis1',
pad: 1.05,
tickOptions: { showGridline: false}
},//yaxis
y2axis: {
showTicks:false,
label: 'axis2',
pad: 1.05,
tickOptions: {showGridline: false}
}//yaxis
},//axes
series:[
{yaxis:'yaxis', label:'s11[0]'},
{yaxis:'y2axis', label:'s11[1]'},
{yaxis:'yaxis', label:'s12[0]'},
{yaxis:'y2axis', label:'s12[1]'},
{yaxis:'y2axis', label:'s21'},
{yaxis:'y2axis', label:'s22'},
]
}); //$.jqplot('chart1', [s1, s2, s3],
}//barchart

我做到了。这是您的代码Jsfiddle Link
上的实现考虑到您必须自己绘制Legends而不是使用jqplot。
如果你能做到这一点，那么我的代码将负责其余部分。
$(document).ready(function () {
var graphObj = [];
var s11 = [["a",1],["b",1],["c",5],["d",2]];
var s12 = [["a",2],["b",2],["c",6],["d",5]];
var s21 = [["a",3],["b",3],["c",7],["d",1]];
var s22 = [["a",4],["b",4],["c",8],["d",8]];
drawBarchart("chart1", s11, s12, s21, s22, 0);
drawBarchart("chart2", s11, s12, s21, s22, 1);
$(".jqplot-table-legend tr").click(function(){
var index = this.rowIndex;
for(var j =0; j<graphObj.length; j++){
graphObj[j].series[index].show = !graphObj[j].series[index].show;
graphObj[j].redraw();
}
