Having the same issue, plus the error thrown:

[Mon Feb 25 12:20:21 2013] [error] [client ***] PHP Notice: Undefined offset: 0 in /var/www/show_graph.php on line 291, referer: http://***/hlstats.php

in ~/hlstatsimg/ there is a folder called progress. This folder needs to be set to 777 as this is where the images are stored.

If that doesn't fix it you may have other issues. Like try install php5-gd.

Hi

Some days ago i had a similar issue, the problem it was because i didnt had installed php-gd on my server, so check for hlstatsx requirements if everything its ok.

Same issue here.


~/hlstatsimg/progress/ is set to 777
releasenotes say GD 2.0.1 is installed


Other graphs work fine, only the player trend graph is not created.




EDIT:
in trend_graph.php I find this SQL query:

SELECT UNIX_TIMESTAMP(eventTime) AS ts, skill, skill_change FROM hlstats_Players_History WHERE playerId = '$player' ORDER BY eventTime DESC LIMIT 30"

I assume this brings the basic data for the creation of the picture.
a) when I watch the table 'hlstats_Players_History' I got only 30 records (but have around 1000 active players) - shouldn't it be many more?
b) and I there is no culmn named 'ts'


Ok, although I can't fully understand the code, I guess it's fine, as it seems to work for others. So it's maybe something wrong with the web part, no?!


EDIT:
Alright in the top of the trend_graph.php it says:

// Load database classes
 require ('config.php');
 require (INCLUDE_PATH . '/class_db.php');
 require (INCLUDE_PATH . '/functions.php');
 require (INCLUDE_PATH . '/pChart/pData.class');
 require (INCLUDE_PATH . '/pChart/pChart.class');

I checked my installation and for some reasons the folder 'pChart' was missing ... -.-
That can be the cause. Now I will wait a few days and lets see if it works.

To have trend graphs working you need your PHP compiled with GD compiled with Freetype support. If you don't host the site on your own webserver, this can be tricky and you might need another host.

I am running HL Stats X on my own Linux webserver, and this was the problem, I needed GD with Freetype support enabled.

You can test this by making a php file like this:

<?
phpinfo();
?>

Save it on the webserver and then acces it from the browser, you should see a long table with all the details of PHP, and check the GD section, it should say "Freetype support: enabled". If you can't find Freetype under GD, or GD section at all, there's your problem!

Hi SINEKT, thx for your help!
I still have no player trend graphs.

I checked the phpinfo as you said:

GD Support: enabled GD Version: bundled (2.0.34 compatible) FreeType Support: enabled FreeType Linkage: with freetype FreeType Version: 2.1.7

:/

[SINEKT]

My FreeType version is 2.4.11, if this helps. I searched for the latest package available and installed that. Also, check the webserver's error logs (Apache or whatever). Usually you find there the PHP function that doesn't work, and you have something to work with (google the error, and finding out how to remove the error).

You host HLStatsX on your own webserver?
