改背景颜色需要用行内样式(允许横向滚动):
<qiun-data-charts type="column" :canvas2d='false' canvasId='canvans3' :onzoom="true" :ontouch="true"
:opts="opts3" :chartData="oxygen" background="rgba(245,245,245,1)" />
注意:yAxis.data至少有一项,不然会报错: [ { position: "left", title: "" } ]
示例:opts: {
canvasId: 'sdfsdf3',
color: ["#1890FF", "#91CB74", "#FAC858", "#EE6666", "#73C0DE", "#3CA272", "#FC8452", "#9A60B4", "#ea7ccc"],
padding: [15, 15, 0, 15],
enableScroll: true,
legend: {
show: false
},
xAxis: {
type: 'grid',
gridType: 'dash',
itemCount: 2, //x轴单屏显示数据的数量,默认为5个
scrollShow: true, //新增是否显示滚动条,默认false
scrollAlign: 'left', //滚动条初始位置
scrollBackgroundColor: '#eee', //默认为 #EFEBEF
scrollColor: '#DEE7F7', //默认为 #A6A6A6
},
yAxis: {
gridType: "dash",
dashLength: 2,
data: [{
position: "left",
title: ""
}]
},
extra: {
mix: {
column: {
width: 20
}
}
}
}
