Highchart：如何计算条形图中每个条形之间的距离

Question

I need to show all the text in label without ellipsis, But I cannot predict the number of lines that the label will take.

1. Is it possible to give some margin between each label and show the bar in center align to label? (with or without varying the distance between each bar)
2. Is it possible to calculate the distance between each bar?
3. Is it possible to calculate the number of lines the label will take?

Here I am setting the height of the chart with number of bars in it with a random guess of each label taking 4 lines.

Image is altered, Sometimes it there are labels with single lines & some times multiple lines.

Example:

Answer 1

This information may be useful in context of the question 3. (answers for questions 1 & 2 appeared in the comments below the question):

Dividing a label text to separate lines (in case when useHTML === false ) is performed in Highcharts.SVGRenderer.prototype.buildText function.

In this live demo I've overwritten this core function and added console.log that prints how many <tspans> were generated for a specific line: http://jsfiddle.net/kkulig/x2619jmv/

It seems that Highcharts may run it multiple times before it finds the proper configuration of the labels.
