title: Plot only plots all the way on the left, and shows black bars instead of x-axes labels
body: <p>I have this plot that is generated by reading a CSV file, for some reason, when plotted it does this very strange thing and squishes the plot all the way to the left of the plot, and replaces the xlabels with black bars. I have included an image of the plot to show you what I mean, as well as the code being used to plot it. Any help would be really appreciated.</p>
  <pre class="lang-py prettyprint-override"><code>def plot_exp(self, filename):  # Plots what is selected using expButton, using the filename from exp_clicked
      self.axes.set_xlim(200, 3000)  # Sets the axes limits
      self.axes.set_xlabel('Energy (eV)')  # Sets the x label
      self.axes.set_ylabel('Intensity (a.u.)')  # Sets the y label
      df = pd.read_csv(filename, sep='\t')  # Reads the .csv file with appropriate separator
      df_exp = df[df.columns[::2]]  # Skips every other column in the .csv file as each is exported twice
      df_exp = df_exp.drop(df_exp.columns[1], axis=1)  # Drops the first column which is irrelevant
      df_exp = df_exp.drop(df_exp.columns[2:7], axis=1)  # Drops columns 2-7 which are also irrelevant
      df_exp.columns = ['Energy', 'Intensity']  # Renames columns
      df_exp = df_exp[df_exp['Intensity'] &gt; 0]  # Only reads data points which are greater than 0
      df_exp['Energy'] = df_exp['Energy'].str.replace(',', '')  # Replaces the comma separator with nothing
      df_exp.to_csv('/Volumes/GoogleDrive/My Drive/MAT 395/Project/Exported Data/Experimental_Plot.csv', index=False)
      # Exports plotted data to .csv
      self.axes.plot(df_exp['Energy'], df_exp['Intensity'])  # Plots the experimental data file
      self.draw()  # Draws the plot onto the canvas
  </code></pre>
