Change Text Size of Chart Labels of facet_grid

[Idris Raja]

I've tried a few options in opts(), including:

legend.title

legend.text

plot.title

What is the option for reducing the text font size for the labels of a facet when using facet_wrap. I've circled the text which I want to reduce the size of in the picture attached.

Thanks

Thanks a lot Hadley & Juan for pointing me in the right direction… this was of course trivial once I had understood the proper use of HEX+ scale_color_identity()

Reproducible version attached..

 

Regards & many thanks

Hi

What you are looking for is strip.text.x (strip.text.y).

strip.text.x did the trick. Thanks.
