我想在光标的右侧显示工具提示。Highcharts tooltip始终在光标的右侧
我查看了文档/示例,但我找不到强制工具提示停留在光标右侧的方法。
谁能告诉我该怎么做?
With tooltip positioner我只能设置一个默认位置。

工具提示定位器远不止是默认位置。函数参数包含有关您的点位置的信息&工具提示尺寸,使用它可以很方便地将它放在右侧。
Highchart/stock allows you to define your alternate positioner如下
tooltip:{
positioner:function(boxWidth, boxHeight, point){
...
}
}
请注意,您在您的处置三个参数(boxWidth,boxHeight,点),这些似乎足以满足大多数的使用情况来计算所需的提示位置。 boxWidth和boxHeight是您的工具提示所需的宽度和高度,因此您可以将它们用于边缘案例来调整工具提示,并防止它从图表中溢出,甚至更糟糕。
附带highstock默认提示定位如下(Source)
/**
* Place the tooltip in a chart without spilling over
* and not covering the point it self.
*/
getPosition: function (boxWidth, boxHeight, point) {
// Set up the variables
var chart = this.chart,
plotLeft = chart.plotLeft,
plotTop = chart.plotTop,
plotWidth = chart.plotWidth,
plotHeight = chart.plotHeight,
distance = pick(this.options.distance, 12), // You can use a number directly here, as you may not be able to use pick, as its an internal highchart function
pointX = point.plotX,
pointY = point.plotY,
x = pointX + plotLeft + (chart.inverted ? distance : -boxWidth - distance),
y = pointY - boxHeight + plotTop + 15, // 15 means the point is 15 pixels up from the bottom of the tooltip
alignedRight;
// It is too far to the left, adjust it
if (x < 7) {
x = plotLeft + pointX + distance;
}
// Test to see if the tooltip is too far to the right,
// if it is, move it back to be inside and then up to not cover the point.
if ((x + boxWidth) > (plotLeft + plotWidth)) {
x -= (x + boxWidth) - (plotLeft + plotWidth);
y = pointY - boxHeight + plotTop - distance;
alignedRight = true;
}
// If it is now above the plot area, align it to the top of the plot area
if (y < plotTop + 5) {
y = plotTop + 5;
// If the tooltip is still covering the point, move it below instead
if (alignedRight && pointY >= y && pointY <= (y + boxHeight)) {
y = pointY + plotTop + distance; // below
}
}
// Now if the tooltip is below the chart, move it up. It's better to cover the
// point than to disappear outside the chart. #834.
if (y + boxHeight > plotTop + plotHeight) {
y = mathMax(plotTop, plotTop + plotHeight - boxHeight - distance); // below
}
return {x: x, y: y};
}
与所有上述信息,我觉得你有足够的工具,通过简单修改功能,使浮来实现您的要求对,而不是默认的左边。
我会继续前进,给你simplest implementation of positioning tooltip to right,你应该能够实现基于后述的默认提示定位器的代码的边缘情况
tooltip: {
positioner: function(boxWidth, boxHeight, point) {
return {x:point.plotX + 20,y:point.plotY};
}
}
如果你是在谈论缺省定位器代码中的注释,那么你应该感谢Highchart团队。如果它的答案作为整体,那么谢谢:) – 2012-08-19 18:43:49
+1很好的答案。 1年后,仍然是我可以找到的最佳答案和谷歌上的#1搜索结果。应该标记为正确的答案。 – 2013-10-29 18:23:52
