hover mode on Chart.js
提问by JohnSnow
Is it possible to have the hover activated when you are not hovering over a specific 'point' in a line graph?
当您没有将鼠标悬停在折线图中的特定“点”上时，是否可以激活悬停？
I want thatparticular tooltip to activate whenever I hover over any part of the chart.
我希望在我将鼠标悬停在图表的任何部分时激活该特定工具提示。

Yes, you can use chart.js to configure tooltips to get a similiar behavior to the chart that you referenced.

tooltips: {
mode: 'x-axis'
},
^^ That will bring up the tooltip when you hover over any y-axis position. If you only want it to show up when you hover over a point on a line, use this:
^^ 当您将鼠标悬停在任何 y 轴位置上时，将显示工具提示。如果您只想在将鼠标悬停在线上的点上时显示它，请使用以下命令：
tooltips: {
mode: 'label'
},
