TH3D cannot be seen in a plot if the value is too small

Dear developers:

Please see the attached files.

If the value in each bin of a TH3D is too small, all the values cannot be seen in the root TBrowser.
If I use the projection, they still cannot be seen, and the number of entries is 0, but mean and rms can be shown correctly.
Now, my only solution to show the TH3D is using scale function to make the value to a “big” one outside the TBrowser.

Who has a solution to show small value in a TH3D?

Thanks a lot.

can you provide a small example ?
