問題文

An author turns on column swapping for a bar graph so consumers can try other columns. What are the limits of what a consumer can do with it?

選択肢

1. The swap reaches every visualization on the canvas at once, and the columns on offer are whichever columns the dataset holds.
2. The swap is offered only where a visualization carries a legend, and the consumer picks from the attribute columns whatever the legend is used for.
3. The swap lasts for that consumer's session alone and cannot be kept in a workbook state, and the author turns the feature on for the whole visualization rather than for one element of it.
4. The swap lasts until the consumer signs out and can be kept in a workbook state, and the author turns the feature on for one element of the visualization at a time.
