Change Highcharts Series color
提问by MacD
EDIT: So now I have a chart with all my data pushed off to the right, BUT I have labels in different colors for the sets I want to show but no data?? Updated my code
编辑：所以现在我有一个图表，我的所有数据都被推到了右边，但我有不同颜色的标签，我想显示但没有数据？更新了我的代码
Original post: I have a working highchart here http://opensourcesurf.com/chart.html. The problem is when I try and change the color of an individual data set, they all change. How could I change these settings given my code? Thanks in advance!
原帖：我在这里有一个工作 highchart http://opensourcesurf.com/chart.html。问题是当我尝试更改单个数据集的颜色时，它们都会更改。给定我的代码，我该如何更改这些设置？提前致谢！
code:
代码：
var options1 = {
chart: {
renderTo: 'container1',
type: 'area'
},
xAxis: {
type: 'datetime'
},
series: [{
name: 'Swell Period',
color: '#0066FF',
data: 'newSeriesData',
},
{ name: ' Maximum Breaking Wave Height',
color: '#ffffff',
data: 'newSeriesData',
},
{ name: 'Swell Height',
color: '#123456',
data: 'newSeriesData',
}],
};
var drawChart = function(data, name, color) {
var newSeriesData = {
name: name,
data: data
};
// Add the new data to the series array
options1.series.push(newSeriesData);
// If you want to remove old series data, you can do that here too
// Render the chart
var chart = new Highcharts.Chart(options1);
};
$.getJSON('decode.php', function(data){
drawChart(data, 'Swell Height');
});
$.getJSON('decode2.php', function(data){
drawChart(data, ' Maximum Breaking Wave Height');
});
$.getJSON('decode3.php', function(data){
drawChart(data, 'Swell Period');
});

Try this:
试试这个：
// 'series' is an array of objects with keys:
// - 'name' (string)
// - 'data' (array)
// - 'color' (HTML color code)
var newSeriesData = {
name: name,
data: data,
color: color
};

The way to specify a color for a specific series is to define it when you're defining the series. For example:
为特定系列指定颜色的方法是在定义系列时定义它。例如：
series: [{
name: 'John',
color: '#0066FF',
dashStyle: 'ShortDash',
data: [
[Date.UTC(2010, 0, 1), 29.9],
[Date.UTC(2010, 2, 1), 71.5],
[Date.UTC(2010, 3, 1), 106.4]
]
},
So essentially when you're creating your series in your drawchart function, do a check for the name, and appropriately assign a color:
所以基本上当你在你的绘图功能中创建你的系列时，检查名称，并适当地分配一种颜色：
var color;
if(name=="Swell Height"){
color="#0066FF";
}else if(name=="Maximum Breaking Wave Height"){
color="#0066EE";
}else if(name=="Swell Period"){
color="#0066HH";
}
var newSeriesData = {
name: name,
data: data,
color: color
};

It looks to me like you are not looping through the array of data and/or you only have one set of data in data.
在我看来，您没有遍历数据数组和/或您在data.
