Python – Limit characters in xticks pandas bar charts

I have the following code:

    df = input_df_.loc[input_df_.index.isin(inds)]
    df = df.drop(expected_metrics+metrics+['AgeNBR'],axis=1).mean()\
            .sort_values(ascending=False)[:25]
    df.plot(kind='bar',width=.4,position=1,color='red')
    full_df = input_df_[df.index].mean()
    full_df.plot(kind='bar',width=.4,position=0,color='blue')

plt.show()

difference = full_df - df

difference.plot(kind='bar',color =  ['r' if x > 0 else 'b' for x in difference.values])
    plt.show()

The code works, but because some x-ticks are very long, the two images end up far apart. Is there a way to limit the size of individual x-ticks Chinese? Similar to the first 7 characters?

Here’s how the questioner solved the problem:

    plt.subplot(1,2,1)
    df.plot(kind='bar',width=.4,position=1,color='red')
    full_df = input_df_[df.index].mean()
    full_df.plot(kind='bar',width=.4,position=0,color='blue')\
        .set_xticklabels([str(tick)[:45] for tick in full_df.index])
    plt.xticks(fontsize=20)
    plt.yticks(fontsize=20)
    plt.gca().set_title('Selected and full feature set averages',fontsize=30)

plt.subplot(1,2,2)     
    difference = df - full_df 

difference.plot(kind='bar',color =  ['r' if x > 0 else 'b' for x in difference.values]).\
        set_xticklabels([str(tick)[:45] for tick in difference.index])
    plt.xticks(fontsize=20)
    plt.yticks(fontsize=20)
    plt.gca().set_title('Selected minus full feature set averages', fontsize=30)
    plt.show()
