Question

我使用blockbuilder.org和Mike Bostock可重用图表技术的一些片段创建了d3图表。

但是，我想为多个图表设置单个y轴。在这里，每当我调用select函数时，我都会为每个折线图创建Y轴。

还有更多我要提到的内容，我必须仅显示最后选择的复选框图表的Y轴，这将是底部图表。

这是我工作的Jsfiddle

以下是onload代码段

＆＃13;

 $(window).load(function () {

            var textareas$ = $('#chartarea div');
            textareas$.hide();
            $('input[name="Air"]').change(function () {

                var elem$ = $(this);
                var correspelem$ = textareas$.eq(elem$.val() - 1);
                if (elem$.val() == 1) {
                    select('Retail', "#Retail");
                } else if (elem$.val() == 2) {
                    select("Gas", "#Gas");
                } else if (elem$.val() == 3) {
                    select("Dining", "#Dining");
                } else {};
                if (elem$.is(':checked')) correspelem$.show();
                else correspelem$.hide();

            });
        });

将此代码添加到您的“更改”中。处理程序：

var chartAxis = document.querySelectorAll('#chartarea  .axis.x');

chartAxis.forEach((elem, index) => index !== chartAxis.length - 1 ? elem.style.display = 'none' : elem.style.display = 'block');
