description: Error occurs when create a third axis. build version: 2.2.2 v20071224-1008 steps to reproduce: 1. New a report. 2. New a datasource with sample DB and new a dataset with table payments. 3. New bar chart. 4. On Select Chart Type page, select Multi-Y Axis as More Axes. 5. On Select Data page, bind the dataset, select customernumber as Series1 of Axis1, create a secondary Axis, select PAYMENTDATE as Series1 of Axis2, create a third Axis.
