Line chart with area shading in Combo chart

[nandini_chatter]

I am trying to achieve a visualization for Predictive Analytics/Forecasting as below in Qlik Sense, with the Dots as the Actuals, line chart in blue as the Prediction and two line charts as forecasted high and forecasted low with the area between them shaded. Any idea how this might be achievable in Qlik Sense? Are there any extensions which can help me with this. Thank you.
