  setXData for depth area chart.

Hello!

I'm using Depth Area chart (http://www.advsofteng.com/doc/cdphp.htm#deptharea.htm)
and I need a custom time values (i.e. 08:00:01, 08:29:37, 08:34:12 etc..)

In line chart I'd used $layer->setXDatamethod, but I cant find how to do this in depth area
chart.

Is this possible?

Thank you.

Hi mephy,

To use date/time values as the x-coordinate, the method for the area chart is exactly the
same as that for the line layer. For example:

$layer = $c->addAreaLayer($data2, 0x808080ff, "Server #1", 3);
$layer->setXData($myXCoor);

$layer = $c->addAreaLayer($data0, 0x80ff0000, "Server #2", 3);
$layer->setXData($myXCoor);

$layer = $c->addAreaLayer($data1, 0x8000ff00, "Server #3", 3);
$layer->setXData($myXCoor);

In the above, the $myXCoor can be an array of date/time in the chartTime representation
(seconds elapsed since Jan 1, 0001 00:00:00).

Hope this can help.
