Zoom in node red charts

Hi, i am trying to show on my dashboard a graph of data from a database. I would like to have the zoom functionality given by plotly and i tried in different ways:

  1. ui-template node: the node seems not able to read dynamic variable and it can't show the graph
  2. python shell node: the code works but it cant create an html file that i can read with iframe node (i already set the directory of the html file in setting.js)
