Fsharp.Charts.Gtk on ubuntu?

[Greg Young]

Has anyone successfully gotten FSharp.Charts working on ubuntu?

stock mono (xamarin package)

needs gtk-sharp so installed gtk-sharp2 package.

have FSharp.Charts.Gtk from nuget package.

/home/greg/src/chart-example/FSharp.Charting.Gtk.0.90.12/FSharp.Charting.Gtk.fsx(33,1):
error FS0078: Unable to find the file 'glib-sharp.dll' in any of
 /usr/lib/mono/4.5
 /home/greg/src/chart-example/FSharp.Charting.Gtk.0.90.12
 /home/greg/src/chart-example
 /usr/lib/cli/fsharp/

glib-sharp.dll is in the gac. copying the .dll to any of these paths is apparently not enough.

Greg, I haven't had chance to try it, but you should give a shot at
adding #I "path/with/glib-sharp.dll"

Also, maybe messing with System.Environment.CurrentDirectory if #I
doesn't work, just to help identify the issue.

I'd give this a shot http://stackoverflow.com/a/19051297

As I am sure people will come across this in the future:

#I "/usr/lib/cli/glib-sharp-2.0/";;
#I "/usr/lib/cli/atk-sharp-2.0/";;
#I "/usr/lib/cli/gdk-sharp-2.0";;

(I just picked random locations where they were, I have plenty and
these were shorter than going into the gac)

I am guessing then the .fsx does some "magic" to try to find things ...

After it works (sort of). My first chart came up quite different than
what the docs say it should:

> let data =
[ "foo", 1024;
"bar", 1234;
"baz", 1456;
"fud", 1777 ];;

Note in chart it uses 1,23,4 on Y axis not the data as in the example:
http://fslab.org/FSharp.Charting/BarAndColumnCharts.html is this a
change in the charting library?

But otherwise it seems to work.

It seems this should be adjusted/extended:

https://github.com/fslaborg/FSharp.Charting/blob/master/src/FSharp.Charting.Gtk.fsx#L28

apparently, mono changed location of assemblies to /usr/lib/cli/

[Greg Young]

I must still be missing something here (perhaps its a very old version
of something?) because the charts don't act like in the examples eg:

> let data =
- [("foo", 1234);
- ("bar", 1543);
- ("baz", 3251);
- ("boo", 1523)];;

or

> let data =
- ["foo", 1234;
- "bar", 1543;
- "baz", 3251;
- "boo", 1523];;

Still result in numbers being drawn for the X/Y axis in Column/Bar
chart. According to docs its should the the first value.

Do I have something out of date or are the docs out of date and there
is a new way?

Hi Greg,

I loaned my Ubuntu laptop (which has Monodevelop on it for F#)  out to a mentee of mine who had no computer for learning programming, and am now down to my Debian-Linux desktop and my Macbook Pro laptop. I have not yet gotten around to test driving FSharp.Charts on my Linux desktop, but since Ubuntu is actually a Debian flavor of Linux, this is something we might be able to accomplish if you want to take a crack at it over a Google video chat/screen-sharing session.
