Plot spherical system without converting to cartation system

I have an spherical coordinate system grid and also intensity value at each of that point, now I want to plot this coordinate system with each data point value, anyone can help me to plot directly spherical coordinate system with data points value.

I tried with converting spherical to cartation and plotting with counterslice but in that intensity value not properly distributed to new system points and results are uneven.

Thanks for the help.
