Question

尝试创建响应式d3图表。我创造了五个功能。

的init（）;
updataScale（）;
updateBar（）;
updateLegends（）;
调整大小（）

在updateBar（）下， d3文本元素的问题在代码中引用（plotGroupText.selectAll（＆＃34; text.grpTxt＆＃34;））。

每当我调整窗口大小时，我都会尝试使用图表中的文本值更新图表。在线上更新文本时，它会创建更多的文本节点，而不是在同一个地方覆盖。 http://jsfiddle.net/mR16/8fc24g4y/2/

Answer 1

由于您按班级选择：

 var barLineText = plotGroupText.selectAll("text.grpTxt")

您必须为文本元素设置相同的类：

.attr("class", "grpTxt")

否则，您将有非空的输入选择。对.grpLabel执行相同的操作。

这是您更新的小提琴：http://jsfiddle.net/68Lp0L4x/

或查看代码段：
