Hello dev-team,
just a few comments/observations I wanted to share with you:
freq:
- an option where multiple (up to 3, e.g.) distributions can be plotted in the same
window would be nice.
- an optional --max command would be nice (if comparing different distributions visually,
it is good if they have the same scale.
Of course, I can do both manually, but it might be something useful in general.
arguments defined by variables:
For the above scenarios, I often calculate the minimum and maximum in a set of functions
and based on this the width as (max-min)/21. It would be nice if one could directly use
these variables with data as input. Instead I have to use sprintf WIDTH = width and then
string substitution "--binwidth=@WIDTH". If I were in a loop (correct me if I am
wrong), I could instead use $width
And then a final remark:
- It would be nice if the size of a dataset would be checked first, when someone clicks on
the "correlations" icon. Otherwise, in large datasets, this can lead to long
waiting times... or the need to shut down gretl without having saved anything. Something
like a pop-up with a warning if one continues, or the like, would be nice.
Kind regards
Frederik

Not directly about histograms, but both these things can be done with
boxplots (View / Graph specified vars / Boxplots).

As hinted at in the doc for 'freq', I'm sure there's a clever way how
this can be done with 'aggregate', but right now I can't tell you :-)

Or a kind of abort button like what we have in script output windows.
But apart from this: So this means you really are using the icon view
and the elements therein?

Hi,
yes I am using it. It is a nice way to past-process some things in an efficient way. I use
gretl to analyse simulation output, so I guess I am not the standard user and I am very
much interested in graphical representations. However, I only clicked on the correlations
button to see what happens ;). Then, while waiting, I consulted the handbook and then
decided to abort.
Thanks for the hint to aggregate (again).
Best
Frederik
