Error Bar

Mean mode and Ratio mode.

The Error Bar has 2 modes, Mean mode, and Ratio mode. The mode automatically switches depending on the column data type and aggregation function that you assign to Y-Axis.

Mean mode

If you assign a numeric column to Y-Axis and choose either "Mean" or "Conditional Mean" for the aggregation function, it becomes the Mean mode. The Error Bar calculation is based on the mean values.

Ratio mode

If you assign a column and aggregation function that don't match the Mean mode criteria above, it becomes the Ratio mode. The Error Bar calculation is based on the ratio of the value counts.
