Free Calendar Visualization with Scrolling Functionality (Calendar Pro Alternative)

[madiaree]

I am currently using the BCI calendar. It is depracated but still usable. The visual fits almost all of my needs, including:

• Shows one month at a time (not an annual view, customizable)
• Can expand into a rectangular view (a lot fo calendar vizs are sqaure)
• Allows you to use a measure (count) instead of each individual event 
• Heatmap (I used a date table for the screenshot, which is why they are all the same hue)

However, I also need the visual to:

• Allow you to scroll through multiple months within a date range. For example, if Jan-Mar is selected, showing Jan to start but having the option to scroll to Feb and March without changing the slicer.
  • BCI would only show Jan, which isn't sufficient for my use-case

The only other visual that fits all of the above criteria is the Calendar Pro by Okviz. This actually fits my needs better than BCI because of the ability to scroll month-to-month. However,  I don't have resources for a license and the free version still asks for one once published. 

As stated, this visual meets all of my needs but I do not have funding for a license.

Is anyone aware of a similar, free alternative?
