Hi JD,

I try to draw date-values which may have some breaks or ends with VOID values, which I put as VOID in the array.
This results in

which is in the function scaleFormat

Any idea for workaound?

Thanks in advance

Good afternoon,

I have difficulties to understand how a timestamp serie can contains VOID values ;o)

To get ride of the error message (and make this function a bit more robust) you can add this test just after the function declaration :



I've commited the change in the next sub release.

Kind regards,
JD.

Thanks for the quick reply,

I will test it.

To help you understanding:

I want to do an Milestone Trend Analysis.
i.e. like this
http://help.sap.com/saphelp_45b/helpdata/en/e1/dde8d801c311d2b6240000e8359ebc/content.htm

This looks interesting (found an easier interpretation here http://www.crestsoft.com/cswmilestn.htm). This is a family of charts that I may implement in the future trough a class extension.

Hi JD,

I solved it. VOID in the php environment is an a constant declared by yourself. Since php is not my first programming language I didn't noticed that, and I wondered why it doesn't work. So if I include your libraries at the very begining all is fine. Sorry for the in inconvenience.

That is correct! The PHP NULL constant is equal to 0 so I wasn't able to use it safely.

No problemo! Happy to help ;o)

Yes,

Milestone Trend Analysis may also be found at Wiki (at least in the German one).

One thing to highlight is that there is normally a diagonal from down left to up right. If a milestoneline cross it - the milestone took place and becomes uninteresting. If you are delayed the milestone will shift to the top.
This makes it very illustrative.
