Different color bar chart from eCharts
提问by Goffer
I was trying to create a different color bar. For Mon blue, Tue red, Wed green. Please help me how to write it. Line itemStyle: {normal: {color: 'blue','red', 'green'}}, did not work.
The code comes from the echarts site.
我试图创建一个不同的颜色条。对于周一蓝色、周二红色、周三绿色。请帮我怎么写。Line itemStyle: {normal: {color: 'blue','red', 'green'}}， 不工作。
代码来自echarts站点。
<html style="height: 100%">
<head>
<meta charset="utf-8">
</head>
<body style="height: 100%; margin: 0">
<div id="container" style="height: 100%"></div>
<script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts.min.js"></script>
<script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
option = null;
option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed']
},
yAxis: {
type: 'value'
},
series: [{
itemStyle: {normal: {color: 'blue'}},
data: [120, 200, 150],
type: 'bar'
}]
};
;
if (option && typeof option === "object") {
myChart.setOption(option, true);
}
</script>
</body>
</html>

This is my solution:
这是我的解决方案：
var option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed']
},
yAxis: {
type: 'value'
},
series: [{
data: [
{
value: 120,
itemStyle: {color: 'blue'},
},
{
value: 200,
itemStyle: {color: 'red'},
},
{
value: 150,
itemStyle: {color: 'green'},
}
],
type: 'bar'
}],
graph: {
color: colorPalette
}
};

The top solution was not working for me. From their documentationis seems lineStyle now has two children elements you can leverage 'normal' and 'emphasis'. I had to modify it like so to override the default colors:
最佳解决方案对我不起作用。从他们的文档来看，似乎 lineStyle 现在有两个子元素，您可以利用“正常”和“强调”。我不得不像这样修改它以覆盖默认颜色：
var option = {
xAxis: {
type: 'category',
data: ['Mon', 'Tue', 'Wed']
},
yAxis: {
type: 'value'
},
series: [{
data: [
{
value: 120,
itemStyle: { normal: { color: 'blue' } },
},
{
value: 200,
itemStyle: { normal: { color: 'red' } },
},
{
value: 150,
itemStyle: { normal: { color: 'green' } },
}
],
type: 'bar'
}],
graph: {
color: colorPalette
}
};

My solution in June 2019 for needing different colors based on values: Create separate series for the different colors, and use a stacked chart. For example, I needed to create a graph with green bars for passing values and yellow bars for failing values. This was my implementation:
我在 2019 年 6 月根据值需要不同颜色的解决方案：为不同颜色创建单独的系列，并使用堆叠图表。例如，我需要创建一个图形，其中绿色条用于传递值，黄色条用于失败值。这是我的实现：
var data = {};
data.legendData = ['Sales','HR','Engineering'];
data.greenSeriesData = ['-',96.38,98.43];
data.yellowSeriesData = [44.23,'-','-'];
var option = {
title: {
text: '2019 Progress',
left: 'center'
},
xAxis: {
type: 'category',
data: data.legendData
},
yAxis: {
type: 'value',
axisLabel: {
formatter: function (val) {
return (val) + '%';
}
}
},
series: [{
data: data.greenSeriesData,
type: 'bar',
stack: 'colorbyvalue',
label: {
show: true,
position: 'insideTop',
formatter: "{c}%",
color: '#000000'
},
barWidth: 50,
itemStyle: {
color: 'green'
}
},
{
data: data.yellowSeriesData,
type: 'bar',
stack: 'colorbyvalue',
label: {
show: true,
position: 'insideTop',
formatter: "{c}%",
color: '#000000'
},
barWidth: 50,
itemStyle: {
color: 'yellow'
}
}],
animation: false
};
