    // Directories for cache and font directory.
    //
    // CACHE_DIR:
    // The full absolute name of the directory to be used to store the
    // cached image files. This directory will not be used if the USE_CACHE
    // define (further down) is false. If you enable the cache please note that
    // this directory MUST be readable and writable for the process running PHP.
    // Must end with '/'
    //
    // TTF_DIR:
    // Directory where TTF fonts can be found. Must end with '/'
    //
    // The default values used if these defines are left commented out are:
    //
    // UNIX:
    //   CACHE_DIR /tmp/jpgraph_cache/
    //   TTF_DIR   /usr/share/fonts/truetype/
    //   MBTTF_DIR /usr/share/fonts/truetype/
    //
    // WINDOWS:
    //   CACHE_DIR $SERVER_TEMP/jpgraph_cache/
    //   TTF_DIR   $SERVER_SYSTEMROOT/fonts/
    //   MBTTF_DIR $SERVER_SYSTEMROOT/fonts/
    //

    // define('MBTTF_DIR','/usr/share/fonts/truetype/');

    //-------------------------------------------------------------------------
    // Cache directory specification for use with CSIM graphs that are
    // using the cache.
    // The directory must be the filesysystem name as seen by PHP
    // and the 'http' version must be the same directory but as
    // seen by the HTTP server relative to the 'htdocs' ddirectory.
    // If a relative path is specified it is taken to be relative from where
    // the image script is executed.
    // Note: The default setting is to create a subdirectory in the
    // directory from where the image script is executed and store all files
    // there. As ususal this directory must be writeable by the PHP process.
    define('CSIMCACHE_DIR','csimcache/');
    define('CSIMCACHE_HTTP_DIR','csimcache/');

    //------------------------------------------------------------------------
    // Various JpGraph Settings. Adjust accordingly to your
    // preferences. Note that cache functionality is turned off by
    // default (Enable by setting USE_CACHE to true)
    //------------------------------------------------------------------------

    // Deafult locale for error messages.
    // This defaults to English = 'en'
    define('DEFAULT_ERR_LOCALE','en');

    // Deafult graphic format set to 'auto' which will automatically
    // choose the best available format in the order png,gif,jpeg
    // (The supported format depends on what your PHP installation supports)
    define('DEFAULT_GFORMAT','auto');

    // Should the cache be used at all? By setting this to false no
    // files will be generated in the cache directory.
    // The difference from READ_CACHE being that setting READ_CACHE to
    // false will still create the image in the cache directory
    // just not use it. By setting USE_CACHE=false no files will even
    // be generated in the cache directory.
    define('USE_CACHE',true);

    // Should we try to find an image in the cache before generating it?
    // Set this define to false to bypass the reading of the cache and always
    // regenerate the image. Note that even if reading the cache is
    // disabled the cached will still be updated with the newly generated
    // image. Set also 'USE_CACHE' below.
    define('READ_CACHE',true);

    // Determine if the error handler should be image based or purely
    // text based. Image based makes it easier since the script will
    // always return an image even in case of errors.
    define('USE_IMAGE_ERROR_HANDLER',true);

    // Should the library examine the global php_errmsg string and convert
    // any error in it to a graphical representation. This is handy for the
    // occasions when, for example, header files cannot be found and this results
    // in the graph not being created and just a 'red-cross' image would be seen.
    // This should be turned off for a production site.
    define('CATCH_PHPERRMSG',true);

    // Determine if the library should also setup the default PHP
    // error handler to generate a graphic error mesage. This is useful
    // during development to be able to see the error message as an image
    // instead as a 'red-cross' in a page where an image is expected.
    define('INSTALL_PHP_ERR_HANDLER',false);

    // Should usage of deprecated functions and parameters give a fatal error?
    // (Useful to check if code is future proof.)
    define('ERR_DEPRECATED',true);

    // The builtin GD function imagettfbbox() fuction which calculates the bounding box for
    // text using TTF fonts is buggy. By setting this define to true the library
    // uses its own compensation for this bug. However this will give a
    // slightly different visual apparance than not using this compensation.
    // Enabling this compensation will in general give text a bit more space to more
    // truly reflect the actual bounding box which is a bit larger than what the
    // GD function thinks.
    define('USE_LIBRARY_IMAGETTFBBOX',true);

    //------------------------------------------------------------------------
    // The following constants should rarely have to be changed !
    //------------------------------------------------------------------------

    // What group should the cached file belong to
    // (Set to '' will give the default group for the 'PHP-user')
    // Please note that the Apache user must be a member of the
    // specified group since otherwise it is impossible for Apache
    // to set the specified group.
    define('CACHE_FILE_GROUP','www');

    // What permissions should the cached file have
    // (Set to '' will give the default persmissions for the 'PHP-user')
    define('CACHE_FILE_MOD',0664);
