[Gambas-user] Charts in Gambas: alternatives to "Chart"

Thu Oct 17 15:03:10 CEST 2013

Lol, this was an old not corrected bug.

Since that I've learn how to manage multiple class instance. Gb.chart have
more than 5 year. And was a proof of concept.

Now I want to make an independant component. We have doing the same for xml
too witch is not based on libxml like the majority of other language.

The iconview, gridview, and many other widget are existing in toolkits but
to get something that reach our ideas we have take the choice to rewrite
them.

The other reason that lead many of us to do that is we love learning new
things. And doing something by ourselves lead to more knowledge.

Don't forget that at the bases, gambas is not made for production. But it
have now the stability to do so.

On many part Gambas is singularly different and offer new way to think a
program development.
I want to keep the way and continue to think things differently if they can
be better.

The goal of gambas is first to learn newbies how to program, second to be
fun and give us please on programming under Unix systems. Third to be the
most powerfull thing If the world.

PS : I hate clouds. I love pc and sync apps.
