Question

我正在尝试使用标签来实现简单的条形图。我正在使用barchart的github graphael示例。

当我尝试将标签功能添加到下面的代码中时，我收到以下错误。在Github上似乎也有open issue。

TypeError: paper.labelise is not a function

错误指出的行号是g.bar.js中的第344行。

有人为此错误找到了解决方法吗？我正在使用Raphaël2.0.2和g.Raphael 0.51。

该行号作为g.bar.js的一部分的代码是： -

var label = paper.labelise(multi ? labels[j] && labels[j][i] : labels[i], multi ? values[j][i] : values[i], total);

抛出此错误的示例代码为： -

Answer 1

我知道它已经晚了，但这是Google搜索同一问题时的第三个结果。我如何解决这个问题是将此文件用于g.bar.js

https://raw.githubusercontent.com/jhurt/g.raphael/master/g.bar.js

然后我就是：

barChart.label([['label1','label2']], true);

为GRaphael条形图添加标签会引发paper.labelise错误
