解决微信小程序使用wxcharts在屏幕不固定问题-开发工具里也显示好了布局，为啥到真机就是乱的
.chart{ 100%; text-align: center; } .canvas{ /* position: absolute; top: 10%; */ 100%; height: 600rpx; transform: scale(0.7) }
js文件里设置了
windowWidth, height: 300, dataLabel: true
开发工具里也显示好了布局，为啥到真机就是乱的？？
已解决：去掉transform scale缩放
js.
new wxCharts({
canvasId: 'ringCanvas',
type: 'ring',
legend: false,
extra: {
ringWidth: 15, //圆环的宽度
pie: {
offsetAngle: -45 //圆环的角度
}
},
series: [{
data: res.data.data.normalNum,
}, {
data: res.data.data.beLateNum,
}, {
data: res.data.data.leaveNum,
}, {
data: res.data.data.uncheckedNum,
}],
320,
height: 200,
dataLabel: false
});
wxml.
wxss. .canvas { z-index: 1; position: absolute; left: 64rpx; top: 120rpx; height: 350rpx; } 还是会乱,如何解决?
项目中如何具体使用wx-charts
// 路径是wxCharts文件相对于本文件的相对路径
var wxCharts = require('./utils/wxcharts.js');
Page({
...
onLoad: function() {
new wxCharts({
...
});
}
});
