[ANIMATION] The direction of motion opened by area chart

[Wdingding]

Original way: The area chart opens from left to right at the same time.

Problem description: The area chart is suitable to be used to present the development trend of data. When it is opened from left to right, the right side of the screen will be blank for a long time.
When the area chart is multiple series, the data trend of each series cannot be clearly displayed at the same time.

Change plan: The line chart opens from bottom to top, and the series behind is displayed first, and then the series before the display is delayed for some time.
