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.
