Shorthands & Store

To assist you with the development we added various shorthands that will make your code more compact.

We also added store functions, which enable you to save either a chart state or a whole animation into a variable that you can reuse later instead of setting up that state or animation once again.

Info - How to setup Chart

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

df = pd.read_csv(
    "https://ipyvizzu.vizzuhq.com/0.17/assets/data/music_data.csv"
)
data = Data()
data.add_df(df)

chart = Chart()

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

chart.animate(
    Config(
        {
            "align": "stretch",
        }
    )
)

Let's save this state by calling the store function.

snapshot = chart.store()

If you set/attach/detach just one series on a channel, you don't have to put that series into an array. Also, let's save this animation by calling the store method of the control chart object.

chart.animate(
    Config(
        {
            "channels": {
                # "x": { "attach": [ "Kinds" ] },
                "x": {"attach": "Kinds"},
                # "y": { "detach": [ "Kinds" ] },
                "y": {"detach": "Kinds"},
            },
            "align": "none",
        }
    )
)

animation = chart.control.store()

If you use set on a channel and no other options like range, you don't have to express that channel as an object. If you only set one series on a channel you can simply write the series' name after the channel name.

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

In any case, you can simply omit the channel object, ipyvizzu will automatically recognize the channels by their names.

chart.animate(
    Config(
        {
            # "channels": {
            "y": "Kinds",
            "x": ["Genres", "Popularity"],
            # }
        }
    )
)

Instead of creating nested objects, you can set the styles like this.

chart.animate(
    Style(
        {
            # "plot": { "xAxis": { "label": { "fontSize": "150%" } } },
            "plot.xAxis.label.fontSize": "150%",
            "title.backgroundColor": "#A0A0A0",
        }
    )
)

Shorthands feature can be switched off if not needed:

chart.feature("shorthands", False)

This is how you can reuse a previously stored animation.

chart.animate(animation)

You can also get back to a state that you previously stored.

chart.animate(snapshot)
