I would like to have all axis labels rendered with the same number of decimals. Currently, I can fix the number of decimals using the format string, but when zooming in, more decimals are often necessary.

In statistics, it is a general consensus to have axis labels with the same numebr of decimal places to indicate the precision level, so I suggest Highcharts to support this, too, without reverting to custom code.

Currently, it can apparently only be done using custom event code, see this Highcharts Forum entry:

Thanks for your consideration!
