title: How to define boundary numbers without decimal points - Choropleth
body: <p><strong>Problem</strong><br>
  The numbers in a legend has the decimal points (eg. 0.00-4.80), when I want them to be integers without decimal points. </p>
  
  <p><strong>My current graph</strong><br>

  <p><strong>My code</strong>  </p>
  
  <pre><code>import geopandas as gpd
  import matplotlib.pyplot as plt
  
  plt.xkcd()
  seoul=gpd.read_file('../json/seoul_municipalities_geo.json')
  # You can download the same file from the Github below

  data_result.plot(figsize=(14,10),linewidth=0.25, edgecolor='black', column='ESRI_PK',cmap='Blues',scheme='quantiles',legend=True)
  
  for index,row in seoul.iterrows():
      xy=row['geometry'].centroid.coords[:]
      xytext=row['geometry'].centroid.coords[:]
      plt.annotate(row['SIG_ENG_NM'],xy=xy[0], xytext=xytext[0],  horizontalalignment='center',verticalalignment='center')
      plt.axis('off')
  
  plt.show()
