#1100 — yrange and ytics don't obey my commands!

Hi there,

I'm frustrated that I can't exactly specify the positions of the major
tics:

set ytics 0.03
set yrange [-0.64:-0.4]
unset autoscale
plot sin(x)

which gives tics at -0.63, -0.60, -0.57, . . . , -0.42 .  Why?  "set
autoscale fix" didn't help.  How can I get the tics at -0.64, -0.61,
-0.58, . . . , -0.4 ?

Cheers,
Ryo

   set ytics -0.64, 0.03, -0.40

Wow.  So simple.  Thank you for the help!

Having said that, isn't this a bug?  When autoscale is unset,
shouldn't ticks be generated strictly from yrange and the tic
interval?

Cheers,

I guess it actually intended that the tics are multiples of the 
separation between two tics, i.e. that there is always one tic at zero. 
In your example, the next tic to your start value -0.64 being an integer 
multiple of 0.3 is -0.63. This is what most users would expect.

Starting at a non-integer tic multiple needs to be specified explicitely.

Best wishes,

Ingo

No need to guess --- the documentation says so quite explicitlz.
