Mixed Daily and Intra-Day Chart

Displaying both daily and hourly data on the same chart is a great way to provide an overview high-level data and more granular details at a glance.

Key implementation details

The trick here is that we add two X axes (one for the hourly and for the daily data) and hide the labels and grid lines on the hourly one by setting forceHidden = true on both templates.
