Hi,
I'm trying to figure out how to not have the spacing around the donut in my <div> element. From several examples, I already set chart.margin, chart.spacing etc as well as the series size to 100%, but initially this kept showing the halo (which I at first thought was called a border), but by disabling the halo, HighCharts still preserves space for it:
This example shows the pie chart in a red box. I want the chart to touch the borders without having to deal with the halo space around it. Is that possible?
