  <blockquote>
  <p>I haven't yet found the history selection bar in any data science tool:</p>
  <ol>
  <li><p>R's <a href="https://www.r-bloggers.com/how-to-plot-with-metricsgraphics/" rel="nofollow noreferrer">metricsgraphics</a> and Shiny seems to be lacking Selection History bar.</p>
  </li>
  <li><p>Python's Shiny-alternatives <a href="https://www.quora.com/Is-there-something-similar-to-R-Shiny-for-Python-users-in-the-scientific-community" rel="nofollow noreferrer">here</a>, such as Bookeh and Spyro, seems to be missing the Selection History bar.</p>
