在按钮上方悬停在图表外时显示饼图的工具提示

问题描述:

http://jsfiddle.net/39UXK/4/

在这个例子中,当我将鼠标悬停在受尊重的按钮上时,我希望看到饼图的工具提示。

in this example I want to see the tooltips of the piechart when i hover on the respected buttons.

有人可以帮我吗?
干杯

Can anyone please help me here ? Cheers

您需要找到有问题的点,选择它并刷新工具提示:

You need to find the point in question, select it, and refresh the tooltip:

// find the point
var point = chart.series[0].points[i];

// select the point
point.select();

// refresh the tooltip
chart.tooltip.refresh(point);
