PowerBI Dynamic Time Series BarChart

Question

Adding on my previous question here: TimeSeries question

I would like to plot a unit capacity chart over a Time series (which contains a range of dates set by the us

Answer 1

To create such a visual, I'd recommend an area chart (or stacked area chart) with the date on the axis, the unit name on the legend, and the capacity on the values. You could also do it as a stacked column chart too. However, then each date will be broken into discrete columns. See below image.

In terms of data manipulation, you'll need to convert the data with the date ranges you have above into a row for each individual date & unit. E.g. the first row, instead of being 11/2 to 13/2, would be expanded into 3 rows, one for each date.

You can do this in Power Query as you bring the data into Power BI Desktop, or in DAX after bringing it in. There are several solutions to this outlined in this thread (https://community.powerbi.com/t5/Desktop/Convert-date-ranges-into-list-of-dates/td-p/129418), but personally, I recommend the technique (and video) posted by MarcelBeug (https://youtu.be/QSXzhb-EwHM).

You'll also want an independent list of dates (with no gaps) to join the final date column to - otherwise your visual will skip dates when no units had capacity. By default, the chart will begin on the first date with data and end on the last date with data, so in that sense it is dynamic, but you can add a date slicer to give the end-user more control.
