var chart = c3.generate({
    data: {
        // iris data from R
        columns: [
            ['data1', 30],

setTimeout(function () {

setTimeout(function () {
    chart.unload({
        ids: 'data1'
    });
    chart.unload({
        ids: 'data2'
    });
}, 2500);

如何添加选项以在c3js中打印图形？或者有没有办法将此c3js从其svg表示转换为canvas。

Answer 1

为什么不直接打印图表div的内容

<div id="chart">
</div>

<input type="button" onclick="printDiv('chart')" value="print a div!" />

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}

Answer 2

试一试。非常简单的css：）

@media print{
  .c3 path, .c3 line {    
    fill: none; 
    stroke: #000;
}

是否有任何选项可以打印c3js生成的图形？
