[yt-users] Problems when using YTSphere.max(...)

Hi together, I want to find out, among others, temperature and pressure values corresponding to a maximum density value within a spherical volume. I thought about using YTSphere.max(…) or YTSphere.argmax(…) for this purpose. However, in both cases I get the Attribute error “ “YTSphere” object has no attribute “max” “ . What might be the error origin? Have I forgotten something obvious?
