Report Studio Bullet Chart – Missing Target

This article describes a common issue in IBM Cognos Report Studio where a bullet chart renders without showing the target bar. The author explains their scenario of visualizing average application processing time against a target value that doesn't exist in the data warehouse, so they created a calculated item. The root cause was the aggregation function property defaulting to 'Automatic' instead of 'Calculated'. Changing it resolved the problem. The article provides a step-by-step technical guide for Report Studio users, focusing on data visualization and chart configuration in business intelligence tools.
