Animation control & keyframes

Using the control property provided by the chart you can play, pause, stop, seek or reverse the animations.

In this step, we seek forward to 50% of progress after the animation starts.

Info - How to setup Chart

import pandas as pd
from ipyvizzu import Chart, Data, Config, Keyframe

data_frame = pd.read_csv(
    "https://ipyvizzu.vizzuhq.com/0.15/assets/data/music_data.csv"
)
data = Data()
data.add_data_frame(data_frame)

chart = Chart()

chart.animate(data)

chart.animate(
    Config(
        {
            "channels": {
                "y": {"set": ["Popularity", "Kinds"]},
                "x": {"set": ["Genres"]},
                "label": {"attach": ["Popularity"]},
            },
            "color": {"attach": ["Kinds"]},
        }
    )
)

chart.animate(
    Config(
        {
            "channels": {
                "x": {"attach": ["Kinds"]},
                "y": {"detach": ["Kinds"]},
            },
        }
    )
)
chart.control.seek("50%")

You can also control the initial position and play state of the animation through the keyword arguments of the animate method.

chart.animate(
    Config(
        {
            "channels": {
                "x": {"detach": ["Kinds"]},
                "y": {"attach": ["Kinds"]},
            },
        }
    ),
    playState="paused",
    position=0.5,
)
chart.control.play()

You may want to control multiple animations as a single one.

You can do this by boundling them together and passing them to a single animate call. To do this, you need to create a Keyframe object from the arguments of every single animate call and then passing them into a single animate call.

chart.animate(
    Keyframe(
        Config(
            {
                "channels": {
                    "x": {"attach": ["Kinds"]},
                    "y": {"detach": ["Kinds"]},
                },
            }
        ),
        duration=0.5,
    ),
    Keyframe(
        Config(
            {
                "channels": {
                    "x": {"detach": ["Kinds"]},
                    "y": {"attach": ["Kinds"]},
                }
            }
        ),
        duration=1,
    ),
)
