Bug#837869: gnuplot: autoscale on y axis buggy with smooth kdensity

[Celelibi]

Package: gnuplot
Version: 5.0.4+dfsg1-3
Severity: normal

Dear maintainer,

It looks like with "smooth kdensity" gnuplot always take the max of the
weights as yrange-max instead of the real max of the plotted function.
Here is an example:

plot 'file.dat' using 1:(1000) smooth kdensity

With these data:
0
100
200

There's an yrange of [0:1000] while the plot itself doesn't exceed the
value 10. The autoscale seems to be completely off.

This bug seems to apply upstream as well.


Best regards,
Celelibi
