title: Is there a simple way to access a single trace from a Plotly figure containing multiple traces (i.e. splom) in Python?
body: <p>I would like to access a trace of a Plotly figure with multiple subplots to plot that trace individually. For example I would like to do the following:</p>
  <pre class="lang-py prettyprint-override"><code>import plotly.express as px
  
  df = px.data.iris()
  fig = px.scatter_matrix(df)
  
  sub_fig = fig.GET_ME_A_TRACE(row=1, col=1)
  sub_fig.show()
  </code></pre>
  <p>Is this possible/feasible in such a way?</p>
