Echarts 如何在条形图上的特定条形之间添加虚线垂直线？
[英]Echarts how do you add dashed vertical line in between specific bars on bar chart?
问题描述
I am working with Echarts and created a bar chart.
我正在使用 Echarts 并创建了一个条形图。 I am trying to add two vertical dashed lines to separate Source3 and Source4 and another dashed vertical line to show separation of SourceSix and SourceSeven .我试图添加两条垂直虚线来分隔Source3和Source4和另一条垂直虚线来显示SourceSix和SourceSeven 。 I have tried messing around with markLine to a bar and adding a line as part of the data after a bar but I can seem to figure this out.我曾尝试将markLine弄乱到条形并在条形后添加一条line作为数据的一部分，但我似乎可以解决这个问题。

I've managed to achieve a similar effect to what you're looking for using the following option: I've converted your x-axis to be a 'value' x-axis, so that we can put markerLines at specific places in between your series.我设法使用以下选项实现了与您正在寻找的类似的效果：我已将您的 x 轴转换为“值”x 轴，以便我们可以将标记线放在中间的特定位置你的系列。 In doing so, you need to assign an x-axis index to each of your data points, but it also allows you to add an additional point to sourceThree and sourceSix which would let you draw a line in between the two as a type:'average' markLine:这样做时，您需要为每个数据点分配一个 x 轴索引，但它也允许您向 sourceThree 和 sourceSix 添加一个附加点，这将使您可以在两者之间画一条线作为一种类型：'平均'标记线：
option = {
title : {
text: 'Chart Title',
subtext: 'subtitle'
},
tooltip : {
trigger: 'axis',
axisPointer:{
show: true,
type : 'cross',
lineStyle: {
type : 'dashed',
width : 1
}
},
formatter : function (params) {
return params.seriesName + ' : [ '
+ params.value[0] + ', '
+ params.value[1] + ' ]';
}
},
xAxis : [
{
type : 'value'
}
],
yAxis : [
{
type : 'log',
axisLine: {
lineStyle: {
color: '#dc143c'
}
}
}
],
series : [
{
name:' SourceOne',
type:'bar',
data:[
[1, 1819931]
]
},
{
name:' SourceTwo',
type:'bar',
data:[
[2, 1291396]
]
},
{
name:' SourceThree',
type:'bar',
data:[
[3, 161], [4, 0]
],
markLine : {
silent: true, // ignore mouse events
data : [
// Horizontal Axis (requires valueIndex = 0)
{type : 'average', name: 'Marker Line', valueIndex: 0, itemStyle:{normal:{color:'#1e90ff'}}},
]
}
},
{
name:' SourceFour',
type:'bar',
data:[
[4, 133279]
]
},
{
name:' SourceFive',
type:'bar',
data:[
[5, 1275]
]
},
{
name:' SourceSix',
type:'bar',
data:[
[6, 119], [7, 0] // this extra data point is the hack to get your marker line in between your series
],
markLine : {
silent: true, // ignore mouse events
label: {show: false},
data : [
// Horizontal Axis (requires valueIndex = 0)
{type: 'average', name: 'Line Marker', valueIndex: 0},
]
}
},
{
name:' SourceSeven',
type:'bar',
data:[
[7, 25224]
]
},
{
name:' SourceEight',
type:'bar',
data:[
[8, 6798]
]
}
]
};
This should result in the following chart, and you can try it yourself by pasting that option here: https://echarts.baidu.com/echarts2/doc/example/bar13.html#这应该会产生以下图表，您可以通过在此处粘贴该选项来自己尝试： https : //echarts.baidu.com/echarts2/doc/example/bar13.html#
