Hello,

I'm looking for a tutorial for TAChart. I started looking at the examples, but there are many things that are made in the OI that I do not understand them, and I can not find any documentation on them, so a tutorial can really help.

Thanks,

Ido

Unfortunately, there is no tutorial currently.
TAChart has documentation in the fpdoc format.
[Rant: It is currently stalled since fpdoc is broken, and FPC team rejected my patch to fix it]

There were a few users who expressed an interested in writing tutorials, but none of them did that.
Maybe I shall write some myself -- but not soon.

Meanwhile, if you have conrete questions -- please ask. I will try to answer extensively, so when/if somebody starts a tutorial, my answers could be used to fill in.

Well, fpdoc is not broken. It simply doesn't support generics. It would be broken if it claimed to support generics and did not.

A patch to support generics is welcome, but it must be a complete patch.

Sorry, Michael, but that is exactly what I am ranting about.

I am tempted to express my opinion in strong words here, but instead I will ask you to look at the recent post by Linus Torvalds, in particular the all-caps words.

https://bugzilla.redhat.com/show_bug.cgi?id=638477#c129

You might want to read the thread entirely -- while it is totally unrelatred to FPC/Lazaurs, it illustrates a problem very similar to the one I notice in FPC development.

A patch to support generics is welcome, but it must be a complete patch.

Sure. Meanwhile, TAChart users will be without documentation.

Ugh. Sorry again -- I was very angered.
Can you please at least answer me in the bug tracker? It have been two months.

I have been busy on the Lazarus book since November, I have looked at the bug tracker very seldomly.

I have answered and gave a workaround for your specific problem.

Michael.
