Draws charts using data from DTML or ZSQLMethod. Plots pie, bar, area, line, hi-lo-close charts and some combinations.

The distribution includes binaries of the gdchart Python module for Windows (gdchart.pyd) and RedHat Linux 6.2 (gdchart.so). Source is supplied for other platforms. The original Python interface to gdchart has been patched. For those who compile from sources, please use the source files enclosed in gdchart-py-0.42b.tgz.

Samples

Here are some samples generated by ZGDChart.

Changes

Version 0.4.2.b introduces DTML data method. More chart styles are now supported. ZGDChart now also accepts runtime parameter overriding.

Installation

For Windows and RedHat Linux 6.x, download ZGDChart_0.4.2.b.tgz and untar it in your root Zope directory. Restart Zope.

For other Unix-flavor platforms, you will need to build the gdchart.so shared library from the enclosed source. Place the generated gdchart.so in the ZGDChart's product folder (replace the existing gdchart.so.) Here are some basic instructions.

Version numbering

The version number is kept in sync with Michael Steed's gdchart.pyd module.

SQL Demo

The DTML data method comes with an automatic sample. For the SQL data method, an SQL example file is included with the distribution since 0.3.3. To import the example, click on the Import/Export tab, and import gdchartdemo.zexp. If everything goes well, you should be able to see 4 charts by viewing the index_html.

Bugs

If the SQL demo is broken on your platform, import gdchartdemo.zexp, delete the ZGDChart object named chartSales and then recreate it. Choose ZSQL for the Data Method. For the SQL connection, choose zsqlSales.

It is known that the Combo_HLC_Bar_3D chart style is currently not working. This is due to a problem in the gdchart Python module.
