- Vertical axis: Select any of `Step`, `Relative time`, and `Absolute time` as the data displayed on the vertical axis of the histogram.
- Angle of view: Select either `Front` or `Top`. `Front` view refers to viewing the histogram from the front view. In this case, data between different steps is overlapped. `Top` view refers to viewing the histogram at an angle of 45 degrees. In this case, data between different steps can be presented.
## Performance Profiler
### Operator Performance Analysis
The operator performance analysis component is used to display the execution time of the operators during MindSpore run.
Figure 17 displays the statistics for the operator types, including:
- Choose pie or bar graph to show the proportion time occupied by each operator type. The time of one operator type is calculated by accumulating the execution time of operators belong to this type.
- Display top 20 operator types with longest execution time, show the proportion and execution time (ms) of each operator type.
Figure 18: Statistics for Operators
Figure 18 displays the statistics table for the operators, including:
- Choose All: Display statistics for the operators, including operator name、type、excution time、full scope time、information etc. The table will be sorted by execution time by default.
- Choose Type: Display statistics for the operator types, including operator type name、execution time、execution frequency and proportion of total time. Users can click on each line, querying for all the operators belong to this type.
- Search: There is a search box on the right, which can support fuzzy search for operators/operator types.

- There are 1000 steps at most for each scalar tag in each training dashboard. When steps exceed limit, MindInsight will sample steps randomly to meet this limit.
- There are 10 steps at most for each image tag in each training dashboard. When steps exceed limit, MindInsight will sample steps randomly to meet this limit.
- There are 50 steps at most for each parameter distribution(histogram) tag in each training dashboard. When steps exceed limit, MindInsight will sample steps randomly to meet this limit.
To limit the data size generated by the Profiler, MindInsight suggests that for large neural network, the profiled steps should better below 10.
