Hello. The function _chartdata in ZGDchart.py returns only one label column and one data column. You may want to change this to: ********************************************************************* def _chartdata(self): """ return the first and second columns of sql query results as a pair of tuples """ rows = getattr(self, self.SQL)() # data[0] is list of labels data = [] start = 0 for row in rows: # each row is a list of fields # initialize empty lists for each column if start == 0: start = 1 for i in range(len(row)): data.append([]) # # Only insert rows with zero values if # it is not a pie chart # Pie Chart only makes sense with 1 data column # for i in range(len(row)): if (self.REQUEST['zgdchart_runtime_type'] != GDC_3DPIE and self.REQUEST['zgdchart_runtime_type'] != GDC_2DPIE) or row[1] != 0: # # Coerce the first field into a string # and other fields into a float # if i == 0: data[i].append( str (row[i])) else: data[i].append( float(row[i])) # # convert lists to tuples # apparently, gdchart.chart() accepts lists # as well, but I better check with # M Steed first. # # I just tried. return data **************************************************************************** *** and restart Zope, which worked for me.

Hi.
This is really a great product.
Unfortunately, I'm not able to create a chart with multiple columns using a
ZSQL Data Method. Multiple columns with a DTML-Method works fine.
Do I miss something. Any ideas?
Thanks for any help. Regards, Marc Ludwig (zope@isp.lu)
