使用 django 绘制 matplotlib

Question

How I can add on my code that I want colors without color yellow because the yellow is just for outliers?

def show_absorbance(df_abs, crop_left, crop_right, clean_param):
    df_abs_t = df_abs.iloc[:, -1].T
    outliers = inf_norm_detection(df_abs,crop_left, crop_right, clean_param)
    colors = list(mcolors.CSS4_COLORS.values())

    plt.figure(figsize=(16, 10))
    plt.subplot(221)
    plt.plot(df_abs.to_numpy()[:, 1:].T, 'yellow')
    for i, outlier in enumerate(outliers):
        plt.plot(df_abs.loc[outlier].iloc[1:],  c=colors[i],label=outlier)
        plt.legend()
    plt.show()

so when I defined here colors , how I remove the yellow?

 colors = list(mcolors.CSS4_COLORS.values())

Answer 1

Use a list comprehension with an if-clause:

 colors = [color for color in mcolors.CSS4_COLORS.values() if color != 'yellow']

Or use whatever the appropriate value for "yellow" is.

For multiple colors, you can use this variant:

 colors = [color for color in mcolors.CSS4_COLORS.values() if color not in ['yellow', 'green']]
