plt.figure followed by plt.plot generate 2 figures in matplotlib python

I am trying to resize the figure when using matplotlib. My code:

%matplotlib notebook

from ipywidgets import interact

@interact(exporter=df.columns.values)
def myplot(exporter):
    plt.close()  # Close a figure window
    plt.cla()    # Clear the current axes
    plt.clf()    # Clear the current figure

    x_ticks  = np.arange(len(df))
    x_labels = [str(date).split("T")[0] if i % 3 == 0 else "" for i, date in enumerate(df.index.values)]

    plt.figure(figsize=(10, 8))
    plt.plot(x_ticks, df[exporter].values)
    plt.title(exporter)
    plt.xticks(rotation=45, ticks=x_ticks, labels=x_labels)

However, I'm getting 2 figures instead of one. Below is the output:
