In the NEWS file, I saw a remark about a new feature: "data filter "bins" sorts input into equal width bins on x" but I couldn't find any mention of it in the regular documentation. It sounds quite interesting and useful - has this been documented somewhere? Also, I seem to remember a "set fit nolog" option, but currently don't seem to find a reference to it anymore. Any hints? Best, Ph. |

Perhaps you have not updated/installed the documentation
matching the current version?
gnuplot> help bins
This option is EXPERIMENTAL (implementation details may change).
Syntax:
plot 'DATA' using <XCOL> {:<YCOL>} bins{=<NBINS>}
{binrange [<LOW>:<HIGH>]}
The `bins` option to a `plot` command first sorts the original data into
equal width bins on x and then plots a single value per bin. The default
number of bins is controlled by `set samples`, but this can be changed by
giving an explicit number of bins in the command.
If no binrange is given, the range is taken from the current x axis range.
Any data points outside this range will be ignored.
If only a single column is given in the using clause then each data point
contributes a count of 1 to the accumulation of total counts in the bin for
that x coordinate value. If a second column is given then the value in that
column is added to the accumulation for the bin. Thus the following two plot
commnad are equivalent:
plot 'DATA" using N bins=20
set samples 20
plot 'DATA' using (column(N)):(1)
For related plotting styles see `smooth frequency` and `smooth kdensity`.

gnuplot> help set fit
The `set fit` command controls the options for the `fit` command.
Syntax:
set fit {nolog | logfile {"<filename>"|default}}
{{no}quiet|results|brief|verbose}
{{no}errorvariables}
{{no}covariancevariables}
{{no}errorscaling}
{{no}prescale}
{maxiter <value>|default}
{limit <epsilon>|default}
{limit_abs <epsilon_abs>}
{start-lambda <value>|default}
{lambda-factor <value>|default}
{script {"<command>"|default}}
{v4 | v5}
unset fit
show fit
