title: How to plot multiple ROC curves in one plot with legend and AUC scores in python?
body: <p>I am building 2 models.</p>
  
  <p>Model 1</p>
  
  <pre><code>modelgb = GradientBoostingClassifier()
  modelgb.fit(x_train,y_train)
  predsgb = modelgb.predict_proba(x_test)[:,1]
  metrics.roc_auc_score(y_test,predsgb, average='macro', sample_weight=None)
  </code></pre>
  
  <p>Model 2</p>
  
  <pre><code>model = LogisticRegression()
  model = model.fit(x_train,y_train)
  predslog = model.predict_proba(x_test)[:,1]
  metrics.roc_auc_score(y_test,predslog, average='macro', sample_weight=None)
  </code></pre>
  
  <p>How do i plot both the ROC curves in one plot , with a legend &amp; text of AUC scores for each model ?</p>
