Cannot set step in an Axis

[DanChaltiel]

I have a XY chart, and my points are measured every 30 minutes.
For this reason, I want to set the step of my xAxis to 30.
For very surprising reasons, the step of ValueAxis is read-only.

I tried the tips written on https://www.amcharts.com/tutorials/user-defined-minmax-values-of-value-axis/, but changing gridcount and labelFrequency could only change step to 20 or 50, but no other value.

It seems wanted by the team, so maybe it's more a feature request.
I may ask why is it wanted if so ?

The step is a calculated value, not a setting, hence it being read-only.

I'm afraid there's currently no way to force 30 min increments on a date-based value axis. The chart will kind of determine it by itself.

You can play around with another setting as well: minHorizontalGap

I hope this will help.

There are no immediate plans to implement a user-defined step setting.

Sorry.

"on a date-based value axis" is this only for date based values, or does this apply to number based values as well

[martynasma]

This goes for all value axes. The chart uses fuzzy logic to determine number of grids/values and thus increments.

As I mentioned previously you can play around with minHorizontalGap (or minVerticalGap for vertical axes) to maybe find a setting that suits your needs and produces increments that you require.
