分别定义三个类选择器,以定义index.hml中组件div、text和chart的样式。 代码如下所示: 复制 container {width: 454px;height: 454px;flex-direction:column;justify-content: flex-start;align-items: center;}.title {width: 240px;height: 90px;margin-top: 40px;font-size: 38px;text-align: center;}....
1、监听窗口resize 2、回调里重新redrawChart 妈蛋,那么简单,下一个! js复制代码window.addEventListener('resize', function() { redrawChart(true); }); 咦。。。咋没效果。。。发生了神马??? 是的=。=,一点点小意外,redrawChart前加个zr.resize();就行了,超纲了, 下一个,。 最后效果。 任务条 -...
keeps changing (getting smaller or bigger depending on devicePixelRatio) the chart size. This can be easily reproduced if you zoom-in or zoom-out in firefox, refresh (verify thatwindow.devicePixelRatiois not 1) and keep doing the mentioned procedure (creting new charts on the same canvas)....
