Example: Advanced plotting¶

---

This example shows how to make the best use of all of atom's plotting options.

The data used is a variation on the Australian weather dataset from Kaggle. You can download it from here. The goal of this dataset is to predict whether or not it will rain tomorrow training a binary classifier on target RainTomorrow.

Load the data¶

In [1]:

# Import packages
import pandas as pd
from atom import ATOMClassifier

# Import packages import pandas as pd from atom import ATOMClassifier

In [2]:

# Load data
X = pd.read_csv("./datasets/weatherAUS.csv")

# Let's have a look
X.head()

# Load data X = pd.read_csv("./datasets/weatherAUS.csv") # Let's have a look X.head()

Run the pipeline¶

In [3]:

atom = ATOMClassifier(X, y="RainTomorrow", verbose=1)
atom.impute()
atom.encode()

atom = ATOMClassifier(X, y="RainTomorrow", verbose=1) atom.impute() atom.encode()

Customize colors and font size¶

In [4]:

# Let's see how the default aesthetics looks like
atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

# Let's see how the default aesthetics looks like atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

In [5]:

# Change the color palette using color names or their hex codes
atom.palette = ["red", "#00f"]

# Change the color palette using color names or their hex codes atom.palette = ["red", "#00f"]

In [6]:

atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

In [7]:

# Change the title and label fontsize
atom.title_fontsize = 30
atom.label_fontsize = 24
atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

# Change the title and label fontsize atom.title_fontsize = 30 atom.label_fontsize = 24 atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

Customize the plot's layout¶

In [8]:

# Use the update_layout method to change layout properties
atom.update_layout(template="simple_white", barmode="group", hovermode="x")
atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

# Use the update_layout method to change layout properties atom.update_layout(template="simple_white", barmode="group", hovermode="x") atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

Customize the title and legend¶

In [9]:

# Let's go back to the default aesthetics
atom.reset_aesthetics()
atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

# Let's go back to the default aesthetics atom.reset_aesthetics() atom.plot_distribution(columns=[1, 2], title="Distribution of temperatures")

In [10]:

# And update the title with some custom fonts
atom.plot_distribution(
    columns=[1, 2],
    title=dict(
        text="Distribution of temperatures",
        font_color="teal",
        x=0,
        xanchor="left",
    )
)

# And update the title with some custom fonts atom.plot_distribution( columns=[1, 2], title=dict( text="Distribution of temperatures", font_color="teal", x=0, xanchor="left", ) )

In [11]:

# We can update the legend in a similar fashion
atom.plot_distribution(
    columns=[1, 2],
    title=dict(
        text="Distribution of temperatures",
        font_color="teal",
        x=0,
        xanchor="left",
    ),
    legend=dict(title="Legend's title"),
)

# We can update the legend in a similar fashion atom.plot_distribution( columns=[1, 2], title=dict( text="Distribution of temperatures", font_color="teal", x=0, xanchor="left", ), legend=dict(title="Legend's title"), )

Using a canvas¶

In [12]:

# Note how the same column over different plots is grouped
with atom.canvas(2, 2):
    atom.plot_distribution(columns=1)
    atom.plot_distribution(columns=2)
    atom.plot_qq(columns=[1, 2], distributions=["norm", "invgauss"])
    atom.plot_qq(columns=[1, 2])

# Note how the same column over different plots is grouped with atom.canvas(2, 2): atom.plot_distribution(columns=1) atom.plot_distribution(columns=2) atom.plot_qq(columns=[1, 2], distributions=["norm", "invgauss"]) atom.plot_qq(columns=[1, 2])
