Highcharts - Display tooltip in column equal to 0 or no value

Question

Hello!

At one time I implemented Highcharts in the Framework in my company, and I can say that we are super satisfied with it. But we have a problem that we don’t know how to solve.

In column charts, when a column has its value equal to zero, no visual information of this is displayed, only the column that is omitted. I would like the tooltip to be displayed when the user hovers over the column space where the value is equal to 0.

See the fiddle below where a bar graph with several columns with 0 or no value is generated.

Could you give me a hint on how to do this?

Answer 1

Solved by inserting the attribute minPointLength in the montage of my chart.
