Introduction
June is Music Month and this week we are getting arty with Charticulator.
In our previous Charticulator challenges, we designed with cartesian plots, spiral plots and tried our hand at nested charts.
For this challenge we use a Polar Scaffold to visualise songs segments by time/duration.
This challenge presumes some Power Query experience. A dataset is available to download in the Data Stories Gallery for those that want to skip ahead.
Requirements
- Download the data for your favourite Beatles song <here> or use the PBIX with existing dataset from the Data Stories Gallery <here>
- Model the data to create fields for Song Attribute, Attribute Name; Start; Finish; Adjusted Finish (calculation adding 0.1 sec to the start time for beats); and Duration (calculation subtracting Adjusted Finish from Start)
-

- Drag the Song Attribute, Attribute Name; Start; and Adjusted Finish fields into the Field Well
- Start new Charticulator Chart
- Drag the Song Attribute on to the Y Axis of the Plot Segment
- Make sure the Plot Segment Sub-Layout type is set to Overlap
- On the Glyph Canvas, draw a Data Axis between the first and last Vertical Guides
- Drag the Start and Adjusted Finish fields on to the Data Axis
- Draw a Rectangle Mark between the Start and Adjusted Finish points, ensure the Mark snaps to guides (If the Glyph Canvas is small and squishy, select the pin to pop-out and re-size. Also select the largest mark size on the main canvas)
- Change the Name of the shape to “Segment”
- Change the colour fill of the Rectangle Mark to bind to the Attribute Name
- Add a new horizontal guide on the Glyph Canvas between the top and middle horizontal guides
- Add a second horizontal guide between the middle and the bottom horizontal guide
- Draw a second Rectangle Mark between the new horizontal guides and the Start and Adjusted Finish points.
- Change the name of the shape to “Chord”
- Change colour fill to black
- Change the visibility of the chord shapes to not show for beats and segments
- For the Segment Shape, adjust the colours to your liking, set the colours for the beats to “none” (ensure Auto Update Values is deselected) or set to the background colour of the visual
- Hide visibility of the Data Axis
- Change the scaffold to a Polar Scaffold, by selecting the Polar Scaffold option in the top menu bar and dragging the icon down on to the Main Canvas
- Add dashed gridlines
- Adjust the sort order of the Y axis to suit.
Dataset
This challenge uses the The Beatles Reference Annotations from isophonics.net http://isophonics.net/content/reference-annotations-beatles
Or you can download the PBIX from the Data Stories Gallery
