TextStyle properties behave inconsistently

[wahlatlas]

within the TextStyle

the following works

        text: (v) => v >100 ? v : '',  
        fontSize: (v, r, s, zf) => zf >1 ? 0.4*r : 0.6*r,
        color: () => 'lime',

but this doesn't (always results in purple or no text)

        color: (v, r, s, zf) => zf >2 ? 'lime' : 'purple',
        text: (v, r, s, zf) => zf >2 ? v : '',

what am I doing wrong?

the original example has the following for color

        color: (v, r, s) => d3.interpolateSpectral(1 - (v - s.min) / (s.max - s.min))

but it should work without D3-scales, I guess
and, more importantly, it should also work dependent on zoom factor

Do I understand correctly that you can control layer visibility with minZoom/maxZoom but that there is no equivalent for styles, yes?

[jgaffuri]

minZoom and maxZoom are available at both layer and style level !
In such a way, you can controle when a layer OR only a style used by this layer or another layer, should become visible or not depending on the zoom factor.

(in fact, a better way would be to model this as a function isVisible which would have as parameters the zoom factor and also the position. So that the layer/style visibility could also be set depending on the map position... and maybe other parameters).

There was indeed a bug there. The color and text were ignoring the zoom factor by mistake.
It was corrected in the newly published 2.0.39 version !
Thanks again for this ! And sorry for these nasty bugs...
