Highcharts text labels for y-axis
提问by Wesley Tansey
I'm using Highcharts and would like to display a simple column graph, but instead of using numeric values for the y-axis, I would like to use text values.
For example, instead of [0,5,10,15,20]I would like to use [Very Low,Low,Medium,High,Very High].
我正在使用 Highcharts 并想显示一个简单的柱状图，但我想使用文本值而不是 y 轴的数值。
例如，[0,5,10,15,20]我想使用[Very Low,Low,Medium,High,Very High].
I noticed it's somewhat possible to do this with plot bands, but that still shows the numeric y-axis labels and just puts the text beside them. I want to only show the text labels.
我注意到使用绘图带可以做到这一点，但这仍然显示数字 y 轴标签，只是将文本放在它们旁边。我只想显示文本标签。

You can change the labels by using a label formatter. Assuming your data is formed appropriately, you can do something like the following:
您可以使用标签格式化程序更改标签。假设您的数据格式正确，您可以执行以下操作：
var yourLabels = ["Very Low", "Low", "Medium", "High", "Very High"];
var yourChart = new Highcharts.Chart({
//...
yAxis: {
labels: {
formatter: function() {
return yourLabels[this.value];
}
}
}
//...
});

Declare an object which will be used to switch the values you want to change, like the following.
声明一个对象，用于切换要更改的值，如下所示。
var change = {
0: 'Very Low',
5: 'Low',
10: 'Medium',
15: 'High',
20: 'Very High'
};
Then on your chart options use labels formatter to switch it.
然后在您的图表选项上使用标签格式化程序来切换它。
yAxis: {
labels: {
formatter: function() {
var value = change[this.value];
return value !== 'undefined' ? value : this.value;
}
}
}
