Are there any ways to manually set the tick labels of `Coordinate Helper`?

I tried  
`ax.coords[2].set_ticklabel(text=['1','2','3'])`  
or directly accessing  
`ax.coords[2].ticklabels.text['t'] = ['1','2','3']`

Both failed.

Hello @yjzhu-solar,

Sorry for the late reply!

There is no good answer for this, the best bet is to use the new astropy 7.0 release which contains this PR: [Allow major formatter to be a callable in WCSAxes by astrofrog · Pull Request #17020 · astropy/astropy · GitHub](https://github.com/astropy/astropy/pull/17020) but its still pretty unintuitive and I am not sure if there is any documentation on how best to use this.
