Make colon in y-axis titles for tooltips optional

[kristofsw]

Hi,

I have noticed that there is no option to not show the colon after the label of a series. I get that it should be followed by the value but in my case I want to display the label below the value (see image below). Without that option, I have to design my tooltip another way which is a bit annoying.

It would be nice if there would be an extra parameter for the y title formatter where you can choose to show or hide the colon (defaults to show).

Is there a way to do this? Thanks in advance.

Good point, I just implemented it.
From the next version, the colon is supplied directly in the formatter instead of hard-coding it.

So, when you change the formatter to below, the colon is removed.

tooltip: {
  y: {
    title: {
      formatter: function(seriesName) {
        return seriesName
      }
    }
  }
}
