Cpan report:
cpan Chart-GGPlot.txt

R's scales::gradient_n_pal() uses the Lab space. Now in Chart::GGPlot we use the RGB space. The two are somewhat different. This would affect the result scale_color/fill_gradient().

https://metacpan.org/pod/Graphics::ColorObject has functions for converting between RGB and Lab space. But this project is not maintained after 2005 and cannot even install. We probabaly can test it and if it's good we can port only what's necessary to our code.

Are there any plans to upload package to conda? I did not have problems installing it separately with cpan but using conda would help to ensure reproducibility of the pipeline.

Now only filled circle is supported. To support various point shapes in a future release.

This would be useful for creating things like heatmap.

This will be something as https://ggplot2.tidyverse.org/reference/geom_smooth.html

In the Perl space the main blocker to have very basic support of this feature is that there is not a LOESS implementation. Need to look at R or Python scikit-misc's implementation and probably to write a separate XS package.

I am currently running Strawberry Perl 5.32.1 on Windows 11 22H2. I am writing scripts to do some bulk data processing which necessitates parallelism. I have discovered that including Chart::GGPlot and any module in Parallel causes failures in forking. The issue is simple to replicate. The following code fails to run:

`use Parallel::ForkManager;
use Chart::GGPlot;
use Autoloader;

my $pm = Parallel::ForkManager->new(3);

$pm->run_on_finish(
sub {
my ($pid, $exit_code, $ident, $exit_signal, $core_dump, $return_ref) = @_;
my $returned = ${$return_ref};
print "Child with ", $returned->{"filename"}, " finished.\n";
}
);

LOOP:
foreach my $file (@argv) {
my $pid = $pm->start and next LOOP;
print "Starting with $file \n";
my $return_data = {};
$return_data->{"filename"} = $file;
$pm->finish(0, $return_data);
}
$pm->wait_all_children;

print "Is this gonna work???\n";`

Note that no error is immediately thrown, and the code simply terminates early. However, commenting out the usage of Chart::GGPlot allows the code to execute to completion. I can also try to fish out error messages if that would be helpful.
Thank you!
