#3130 — z tics format affected by zrange

Hello,

In version 5.0.1, the following piece of code (automatically generated by another program)

set zrange [8.87e-10:200.0]
splot x**2+y**2

writes numbers on the z axis with 10 decimal places. Is this intended behavior?

In previous versions, numbers were written in a more friendly format.

Thanks.

That's a known problem, although I thought it should have been the
same in the 4.6 series, see also

http://sourceforge.net/p/gnuplot/bugs/1667/ .

gnuplot's default format "% h" tries to adjust itself depending on
the range values, and this goes wrong in some cases.

There's not yet a good idea (i think) how to properly fix this,
because it might change the behaviour of the stable version in other
places.

For the time being, you could switch the format to explicitly use
"%h" (note the missing space), or adjust that other program to give
more sensible range specifications. Something like

set zrange [floor(zmin):zmax]

or similar should do the trick.

Thanks for the response. I'll take into account your comments.
