推荐答案

您可以在

You can register a custom function in postDrawHooks, to be fired after plugin initialization.

想法是使用此功能在图表顶部绘制一个白色边框矩形，从而使外部边框不可见.

The idea is to use this function to draw a white border rectangle on top of the chart, that makes the outside borders invisible.

$.jqplot.postDrawHooks.push(function() {
    var $canvasMain = $("#chart1 canvas.jqplot-grid-canvas"),
        $canvasLines = $("#chart1 canvas.jqplot-series-canvas"),
        canvasSize = { 
            x: parseInt($canvasLines.attr('width')), 
            y: parseInt($canvasLines.attr('height'))
        },
        ctx = $canvasMain[0].getContext('2d');

    ctx.strokeStyle = 'white';
    ctx.lineWidth = 6; // 6 to hide shadows and the larger bottom side
    ctx.rect($canvasLines.position().left,
             $canvasLines.position().top,
             canvasSize.x,
             canvasSize.y + 3);
    ctx.stroke();    
});

jsFiddle

您可以看到外部边界消失了:

You can see that the outside borders are gone:

这很好用，但是我个人将继续修改源代码以跳过外部边界.该插件已获得GPLv2和MIT的双重许可，因此我认为该路线没有问题.

This works fine, but personally I would just go ahead and modify the source to skip the outside borders. The plugin is double licensed with GPLv2 and MIT, so I guess there are no problems going that route.

我发现，如果您对此进行更改

I found out that if you change this

grid: {borderColor: 'transparent', shadow: false, drawBorder: false, shadowColor: 'transparent'},

到

grid: {borderColor: 'white', shadow: false, drawBorder: true},

外部边界消失了(类似于我上面所做的事情)，但是在x轴上仍然出现了一些刻度线.我已将showTickMarks: false设置为未成功.

the outside border disappears (kind of what I do above), but still some tick marks on x axis appear. I've set showTickMarks: false to no success.
