HighCharts - 在值为0或null的列上显示工具提示 [英] HighCharts - Show tooltip on column where value is 0 or null
问题描述
我在公司的框架中实施了HighCharts，我可以说我们对它非常满意。但是我们有一个问题，我们不知道如何解决。
I had implemented the HighCharts in the framework in my company, and I can say that we are super satisfied with it. But we have a problem, we don't know how to solve.
在列图中，当一列的值等于零时，它没有关于它，该列只是省略。当用户将鼠标悬停在值等于0的列的空间上时，我希望它显示在工具提示中。
In column graphs, when a column has its value equal to zero, it is no visual information about it, the column is just omitted. I want it displayed in a tooltip when the user mouses over the space of the column where the value is equal to 0.
观察下面的小提琴生成条形图的位置有几个值为0或无价值的列。
Watch the fiddle below where it generates a bar chart with several columns with value 0, or worthless.
图表运行的方法：
GraficoBarra(arrayPropriedades, arrayDados, arrayDrillDown);
推荐答案
正如@wergeld所说，你需要通过0-基于值的选项，否则您将不会显示任何内容。对于空值，它是不可能的，因为它没有价值。
As @wergeld said, you need to pass 0-based values to options, otherwise you won't get displayed nothing at all. For nulls it's no possible, since this doesn't have value.
现在，您需要将 minPointLength 设置为某个值（如10），然后甚至0值将显示为小条。请参阅演示： http://jsfiddle.net/EJK4e/12/
Now,you need to set minPointLength, to some value (like 10), then even 0-values will be displayed as small bars. See demo: http://jsfiddle.net/EJK4e/12/
只是为了在同一页面上 - 要显示工具提示，你需要点图形，否则将没有用于触发工具提示显示的悬停事件。
Just to be on the same page - to display tooltip, you need point graphic, otherwise there will be no hover event for triggering tooltip to show up.
