我正在使用 jqplot 绘制饼图、条形图和折线图。它在 IE9>= 中工作正常。但它在 IE8 中不起作用。当我同时使用饼图和条形图时，它给了我上述错误。它在 e.jqplot.PieRenderer 的饼图插件中显示错误。阻止此插件条形图后可以正常工作，但不能使用饼图。下面是我的代码。请就此提出建议。
var optionsObj = {
title: 'Item wise stock',
animate: !$.jqplot.use_excanvas,
axes: {
xaxis: {
renderer: $.jqplot.CategoryAxisRenderer,
ticks: dates,
label: 'Item'
},
yaxis: {
tickOptions: { showMark: true, formatString: "%d" },
padMin: 0,
label: 'Stock',
angle: -30,
labelRenderer: $.jqplot.CanvasAxisLabelRenderer,
labelOptions: { fontSize: '11px' }
}
},
grid: {
drawGridLines: true, // wether to draw lines across the grid or not.
gridLineColor: '#cccccc', // *Color of the grid lines.
background: '#e6e6e6', // CSS color spec for background color of grid.
borderColor: '#999999', // CSS color spec for border around grid.
borderWidth: 2.0, // pixel width of border around grid.
shadow: true, // draw a shadow for grid.
shadowAngle: 45, // angle of the shadow. Clockwise from x axis.
shadowOffset: 1.5, // offset from the line of the shadow.
shadowWidth: 3, // width of the stroke for the shadow.
shadowDepth: 3, // Number of strokes to make when drawing shadow.
// Each stroke offset by shadowOffset from the last.
shadowAlpha: 0.07, // Opacity of the shadow
renderer: $.jqplot.CanvasGridRenderer, // renderer to use to draw the grid.
rendererOptions: {} // options to pass to the renderer. Note, the default
// CanvasGridRenderer takes no additional options.
},

],

<tr><td>Stock:</td><td>' + data[pointIndex][1].toString() + '</td></tr></table>'
}
}
};
var plot2 = $.jqplot(location, values, optionsObj);
