Welcome

  Zope 2.7 Required for ZGDChart 0.6.5
 
    If you are using Zope 2.6 or older, use ZGDChart 0.6.4
    The binaries for 0.6.5 have been compiled against Python 2.2
 
  Building the gdchart module

    The RedHat GD binaries work fine with !SuSE Linux (6.4/7.0). You don't
    have to compile your own ones ...

    If you are having trouble building gdchart module on your platform,
    have a look at the survival guide. I've had a few reports of build
    difficulties. 

    I only have access to a Win9x box, so I can't tell you what's wrong
    with Linux or Solaris builds. I can only suggest that the makefiles
    have been doctored to get all the libraries working on my system.
    Hung Jung Lu had very kindly provided the Linux binaries for 
    your convenience. The prebuilt libraries (libgd.a, libjpeg.a etc) 
    are useless if you are not building on Win9x systems. You'd have to
    delete them and rebuild them again.

    If you succeed in building the module for your platform, post it here
    for the benefit of everybody. Thanks!

    Solaris Binaries (up to Zope 2.3)

       Marcus Bursik took the time to contribute the Solaris 
       binaries 
       "http://www.zope.org/Members/teyc/ZGDChart/gdchart.so":gdchart.so
       *Included in 0.5b*
  
    Linux Binaries (Zope 2.4)

       Chris Withers provided the Linux binaries for *Zope 2.4*
       "gdchart.so":http://www.zope.org/Members/teyc/ZGDChart/linux/gdchart.so
       (302 kb)

  Chris reports

       The grid lines were very close for dense data that it grays out
       the background.

       A quite simple method to receive bigger fonts and not so narrow lines:

       1. I set the original size of zgdchart as small as possible, 
          e.g. width  250 and height 90 pixels 

       2. I size the target place in the dtml-document 400 
          respectively 290 pixels.

  How-to change output image format

       "Renato De Giovanni":mailto:[email protected] provided this
       short how to:
  
       1. download "gdchart-py-0.5.tar.gz" from
          http://athani.pair.com/msteed/software/gdchart/

       2. untar, unzip and compile the library (by default 
          gif and jpeg creation are already enabled)

       3. copy "gdchart.so" to your ZGDChart directory.

       4. Edit ZGDChart.py and add the following line on the 
          end of "_setOption" method:

          eval("option(format=GDC_JPEG)")

     note 1

        format codes are: GDC_PNG, GDC_GIF and 
        GDC_JPEG (default is png).

     note 2 

        I used gnu/linux.

Subject: ZGDChart broken?
Message-ID: <[email protected]>

I've been trying to install ZGDCarts into a clean plone installation, without luck. I copied the directory structure to the products dir, and after restarting plone, the product IS listed in the products folder, but the examples report it broken, and it doesn't appear in th add item drop list.

Any hints?
Mariano
