Preface
Echarts is my most commonly used chart tool, and it is also a very complete ecology and content, enough for us to use normally.
Usage
1. Cancel the grid of the chart and modify the color of the grid
/ / controls whether gridlines display splitLine: {show: false, / / whether gridlines display / / change the style lineStyle: {color:'# ccc' / / modify gridlines color}}
2. Style modification of coordinate axes
XAxis: [{type: 'category', boundaryGap: false, data: [January', 'February', 'March', 'April', 'May', 'June'] AxisLine: {lineStyle: {color: "# ccc"}}, axisTick: {show: false / / remove scale}, axisLabel: {/ / font style modification show: true / / Show hidden textStyle: {color: "# ccc"}}, / / Control whether gridlines display splitLine: {show: false / / whether gridlines are displayed / / change the style lineStyle: {color:'# ccc' / / modify gridlines color}},}] YAxis: [{type: 'value', name:' (times)', axisLine: {lineStyle: {color: "# ccc", fontSize:'16'}} AxisTick: {show: false / / remove the scale},}]
3. Some style modification or configuration of the donut chart
/ / the style of the text in the center of the ring is modified title: {text: value.value+'', subtext: value.name, x: 'center', y:' center', itemGap: 0, textStyle: {fontSize: 26, fontWeight: 'bold', color:' rgb (0237255)'} SubtextStyle: {fontSize: 16, fontWeight: 'bold', color:' # fff'},}, / / the floating effect of mouse movement in the ring clears series: [{hoverAnimation:false,// adds this attribute}]
4. Switch multiple charts to clear the last loaded data.
Add trueoption & & myChart.setOption (option,true) to setOption
5. Use the gradient color of the chart.
Echarts.graphic.LinearGradient
Series: [{type: 'pie', center: [' 50%','49%'], radius: ['45%','73%'], / / minAngle: 0, startAngle: 0, / / gradient angle avoidLabelOverlap: true / / whether to enable emphasis: {label: {show: true, position: 'center'}}, data: seriesData, itemStyle: {emphasis: {shadowBlur: 10, shadowOffsetX: 0 ShadowColor: 'rgba (0,0,0,0.5)', label: {show: true,}} Normal: {color: function (params) {/ / Color gradient var colorList = [{C1:'# 3288FCY, c2:'# 36B4FD'} {C1:'# CBA0FF', c2:'# 598 EFE'},] return new echarts.graphic.LinearGradient (1,0,0,0) [{/ / the first four parameters of the color gradient function indicate that the four positions are left, bottom, right and top offset: 0, color: colorList [params.dataIndex] .c1}, {offset: 1 Color: ColorList [params.dataIndex] .c2})}] these are all the contents of the article "how to use vue+echarts Chart" Thank you for reading!
