Suds - the blue line is the 20 day moving average. If you look in the top left corner you will see 3 lines listed. Only the 20 day line is shown as the company ony existing with its current name for a short period so the others done have sufficient data to display.
Probably easier to explain with this as an example
This is CBA, and you can see the 3 different lines. Many chartists consider the crossing of one or more of these lines to be significant, both up and down. Some traders will use these event to start an interest in a stock, or dump it.
A lot of macro longer term investors prefer the weekly chart
