Hi,

The following code gives strange results (Scilab version  
“6.1.1.1626343451”, on Ubuntu 22.04)

plot(1e-8\*rand(1,5))

the y-axis and the y\_ticks are not only limited to the the graphic window. It works fine with higher values.  
Is it a bug with low value?

Hello,

Thanks for posting in Scilab’s discourse !

The problem you ar reporting is a very old/annoying bug (see [plot2d([1 2]\*1e-14): Y-axis extending out of its range for small Y values (#16029) · Issues · scilab / scilab · GitLab](https://gitlab.com/scilab/scilab/-/issues/16029)) your command:

```auto
plot(1e-8*rand(1,5))

```

yields the following plot in Scilab 6.1.1:

This bug has been fixed 2 month ago (see [Fix #16029: tick marks were out of range for small scale plots (!4) · Merge requests · scilab / scilab · GitLab](https://gitlab.com/scilab/scilab/-/merge_requests/4)) and this plot will be OK in Scilab 2023.0 (below plot has been made with a recent continuous build of Scilab):
