as it was in Code Analyst?
I found no timeline picture for CPU at all in CodeXL so far. Only for GPU API trace.
In CodeXL 1.1 only OpenCL API is displayed in a graphic CPU + GPU timeline representation.
Most of CodeAnalyst features are already present in CodeXL. Those features that are still missing will be added to CodeXL in its upcoming releases.
I believe you're referring to the CodeAnalyst CPU Thread Profiling feature which displays its results in a timeline chart. This feature has not yet been added to CodeXL.
