title: Adding upper / lower limits and changing x-axes value format in Dash Plotly
body: <p>I’ve been working on a mini project using Dash Plotly to visualize some factory data I found online and I have a couple of questions that I could not find answers to.</p>
  <ol>
  <li><p>How to change the format of x-axes values ? My values are in the thousands and Plotly defaults it to 20k, 22.5k, 25k etc. I actually want it as 20000, 22500, 25000.</p>
  </li>
  <li><p>While I am able to plot x and y values from the data frame easily, my data has upper and lower limits (same scale as y values) to determine pass fail criteria. These limits are in separate columns in the data frame. How do I plot these limits for every corresponding x value ?</p>
  </li>
  </ol>
  <p>Thanks for your help!</p>
