Numeric format in 3D graph legend
 

Created 2 sheets of data and drew 3D graphs for each of them.

The legend of the first one is in format of one decimal digit,
the other graph, however, is in four digits of decimal number.

Want to change this four digits to one. But cannot find where
to manipulate. Where is it?

The sheet cells are in 4 digit format for both. Z axes are in
one digit format.
