How to show only integer values on yAxis of HighChart?
提问by wergeld
We have a set of a data that contains counts of instances of events. These can only be integers. When we display data that has a high enough yValue the yAxis labels are integers. However, when we zoom in to ranges of data that have under y = 5 we see the tick markers show things like 0.5, 0.75, 1.5, etc. How can we force the yAxis labels to only show integer values?
我们有一组包含事件实例计数的数据。这些只能是整数。当我们显示具有足够高 yValue 的数据时，yAxis 标签是整数。但是，当我们放大到 y = 5 以下的数据范围时，我们会看到刻度标记显示 0.5、0.75、1.5 等。我们如何强制 yAxis 标签仅显示整数值？
Hereis an example bit of code with some data. As you zoom in to the lower value region of the chart you can see what I mean. This is the current yAxis setup:
这是带有一些数据的示例代码。当您放大图表的较低值区域时，您可以看到我的意思。这是当前的 yAxis 设置：
yAxis: {
labels: {
style: {
fontSize: '9px',
width: '175px'
}
},
title: {
text: ''
}
},

Set the allowDecimalsoption in the y axis to false in order to prevent non integer tick marks from being displayed:
将allowDecimalsy 轴中的选项设置为 false 以防止显示非整数刻度线：
yAxis: {
allowDecimals: false,
labels: {
style: {
fontSize: '9px',
width: '175px'
}
},
title: {
text: ''
}
}
