<P> Week scales, if enabled, by default shows the week number in range 1
|
|
|
30 |
to 53 (as defined by ISO-8601, see the reference section).</P>
|
|
|
31 |
<P> It might be worth pointing out here that the week number calculation
|
|
|
32 |
is carried out within JpGraph and does not rely on the underlying OS
|
|
|
33 |
date libraries. This makes the behavior consistent over several OS:s
|
|
|
34 |
(at least M$ Windows does<B> not</B> comply to ISO-8601 or supply any
|
|
|
35 |
way of doing this through the normal libraries, e.g. strftime())</P>
|
|
|
36 |
<P> You may modify the week behavior in three ways. You can specify
|
|
|
37 |
(with SetStyle()) a different date format using the constants</P>
