Well, ARTIO solved my request with a complicated sql query that turn a normalized table in a data structure compatible with the ARTIO extension.
I wonder if the extension itself should be modified a little bit so to be able and get data from normalized db as most of the data are in this form.
Anyway, for the moment I thank ARTIO for the quick support!!

Lubi, you were right...sorry!! Uninstalling the free version was not enough for deleting the db tables...I had to manually execute sql drop tables.
Now everythig is fine...thank you again!!

SOLVED

Hello again, I've just added an image of the error...it just don't save anything...even the dummy chart made by ARTIO itself when you create a new chart. Again, uninstalled and installed the extension...the free one doesn't have the same behaviour.
I found another user having the same issue...

Any solution anyone???
Tks,

Yes, I did install the free version but I've unistalled it before the new one. I've tried now again but the error did happen again...sigh!

Hello, I'm trying to get the multi-series line 2d chart working. I'll make it as simple as I can:
A table has a 3 column: date, coke_price, pepsi_price.
The idea is to have a chart with date as x axis, prices as y axis...the lines show coke and pepsi prices going up and down, comparing the two.

The problem?? As I understand it...the x axis values are taken from the column names (date, coke_price and pepsi_price) and I don't get the reason for that...I'm quite new at SQL but I wonder why I should turn a table this way...and most of all...how can I do that??? Should a table be designed as I did?
What is wrong with it??
Thank you for your patience.
