离开画布时，chartjs 工具提示被切断 [英] chartjs tooltip is cut off when out of canvas

问题描述

我目前正在使用 chartjs (

解决方案

有多种解决方法.

一种方法(在你的情况下)，你可以解决这个问题，就是为你的图表布局设置底部填充，就像这样......

选项:{布局: {填充:{底部:25//最适合的设置}},...}

ᴅᴇᴍᴏ

var ctx = document.getElementById("myChart").getContext('2d');var myChart = new Chart(ctx, {类型:'线'，数据: {标签:['一月'，'二月'，'三月'，'四月'，'五月'，'六月'，'七月'，'八月'，'九月']，数据集:[{标签:'标准评级'，数据:[0.1, 0.02, 3, 4, 5, 6, 7, 8, 9],backgroundColor: 'rgba(209, 230, 245, 0.5)',borderColor: 'rgba(56, 163, 236, 1)',边框宽度:1}]},选项: {布局: {填充:{底部:25//最适合的设置}},响应:错误，工具提示:{yAlign: '顶部'}}});

I'm currently using chartjs (chartjs).

Tooltip is cutted, because it go out of canvas. How I can fix this behavior?

解决方案

There are multiple ways of solving this.

One way (in your case), you can solve this, is by setting the bottom padding for your chart layout , like so ...

options: {
   layout: {
      padding: {
         bottom: 25  //set that fits the best
      }
   },
   ...
}

var ctx = document.getElementById("myChart").getContext('2d');
var myChart = new Chart(ctx, {
   type: 'line',
   data: {
      labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sept'],
      datasets: [{
         label: 'Standard Rating',
         data: [0.1, 0.02, 3, 4, 5, 6, 7, 8, 9],
         backgroundColor: 'rgba(209, 230, 245, 0.5)',
         borderColor: 'rgba(56, 163, 236, 1)',
         borderWidth: 1
      }]
   },
   options: {
      layout: {
         padding: {
            bottom: 25  //set that fits the best
         }
      },
      responsive: false,
      tooltips: {
         yAlign: 'top'
      }
   }
});

<canvas id="myChart" width="350" height="200"></canvas>
