title: Barplot with twinx and two bars per month

  <p>Those columns shall be ploted against the month with seaborn to get a barplot with two y-axis. One for 'Ta' and one for 'G_Bn'. The bars have to be next to each other. My idea:</p>
  <pre><code>#Create combo chart
  fig, ax1 = plt.subplots(figsize=(20,10))
  ax1 = sns.barplot(data=dataMonthly, color ='#2b83ba')
  ax1.tick_params(axis='y')
  ax1.set_xlabel('Time')
  ax1.set_ylabel('Value1')
  
  ax2 = ax1.twinx()
  ax2 = sns.barplot(x = dataMonthly.index, y = &quot;Ta&quot;, data=dataMonthly, color =&quot;#404040&quot;)
  ax2.set_ylabel('Value2')
  ax2.tick_params(axis='y')
  plt.show()
  </code></pre>
  <p>The problem is that the bars do always lay on top of each other because I plot on ax1 and then  ax2. How do I solve it? Any ideas?</p>
