title: Tensorboard only showing dots, line not showing
body: <p>I am using tensorboard through pytorch and have created a scaler which shows accuracy, loss, and validation accuracy.  When I open the graph it only shows dot and dosen't show a line connecting these dots.</p>
  <p>Here is a snippet of my code</p>
  <pre><code>tb = SummaryWriter(comment=f'-{epoch}')
  
  tb.add_scalar(&quot;Accuracy&quot;, float(correct/len(train_tensor)*100), epoch)
  tb.add_scalar(&quot;Loss&quot;, loss, epoch)
  tb.add_scalar(&quot;ValiAccuracy&quot;, float(correct/len(train_tensor)*100), epoch)
  tb.close()
  </code></pre>
  <p>What is leading tensorboard to not show these lines?
