I assume the error below is due to not having a full set of data available yet?

Warning: array_reverse() [function.array-reverse]: The argument should be an array in C:\wamp\www\CHHP\graphs\baro.php on line 117

JpGraph Error Empty input data array specified for plot. Must have at least one data point.

Yes.

JpGraph will error out if it doesn't have at least 1 data point.

Depending on what frequency you using, the only data that is looked at is

Code:

freq=0 (default) once an hour - 00 minute
freq=1 twice an hour - 00 and 33 minutes
freq=2 4 times an hour - 00, 15, 30, 45 minutes

Got past that error but now strike this one

Fatal error: Call to undefined method Text::Pos() in C:\wamp\www\CHHP\graphs\baro.php on line 139

realtime.log has 100 sets of data in it.

It seems to me to be a position error in the baro.php code

Off course I forgot to put the ttf fonts in the jpgraph ttf dir duh, found that but still having an issue

This is more of the graph file issue than the realtimelog file issue.

What version of JpGraph are you using?

arthurhh · **Posted:** Sun Oct 12, 2008 1:10 am

2.3.3

Same as I use for the JPGRAPH stuff on my WD site

Possible it is not getting the array populated???

TNETWeather · **Posted:** Sun Oct 12, 2008 1:24 am

Is it only the baro.php script??

I almost put debug code in the scripts... perhaps I should...

In the baro.php script after the section that looks like:

Code:

$x = array_reverse($rx);
$y1 = array_reverse($ry1);

add the following code and run the script.

Code:

echo "<pre>";
print_r($x);
print_r($y1);
exit;

It should run and output the two arrays of information.

Other info:

What is the URL to your realtime.log file. If you prefer, PM me the info.

yep as I suspected, now to examine my paths. The result is two empty arrays

Array

Array

My realtime log file is http://chh-p.dyndns.org/realtime.log

When I get a chance I will put some debug stuff in there. I half had some in there when I was working on the temp.php script but I ripped it out when I cleaned up the code mess to get it ready.

It does have the ability to view the code... http://yourserverpath/baro.php?view=sce but that doesn't show what data it sees.

I did just add a PDF document for the package... but again, that is for the JpGraph stuff not RealTimeLog.

The realtime log appears to be working as expected, it generates realtime.log entries as required.
The issue is with the graph php not reading this, now I am strictly a mod with cut and paste type with PHP so I get stuck real easy.

TNETWeather · **Posted:** Sun Oct 12, 2008 1:56 am

Is this with just one graph or all of them?

arthurhh · **Posted:** Sun Oct 12, 2008 2:11 am

All of them, but I have just twigged that I need to call them in a page with the freq specified so i tried your samp-graph.php and while it generates no errors it doesnt generate any graphs.

I have the real time stuff in the root of the site and the graph files in a sub called graphs. pathing to jpgraph is correct

TNETWeather · **Posted:** Sun Oct 12, 2008 2:37 am

Contents removed.

The new version will have a debug mode in all the graphs.

arthurhh · **Posted:** Sun Oct 12, 2008 9:53 pm

I have to go shake my fist at the staff for a couple of days, will look at testing this later in the week.

.
Version 1.2

The newest release of these scripts include CLI support (Command Line Interface) so that the scripts can be called using a scheduler (like crontab) passing options to get the results you are looking for, they have new debugging code in them to assist in determining problems that people might have trying to use them, a new info display which shows on the graphs the number of hours that are represented and the frequency sample and better documentation.

You can download the scripts from my project page....

TNET Cumulus Project Page

The package includes PDF documentation and a copy of the ServerCheck script for those just starting out to use to make sure they have the proper web server configuration to use the scripts.

You can download the PDF file separately from the download page as well.

Enjoy...
