How I Created The Bubble Chart
GfK provided data on dollar and unit sales of smartphone by region in 2016 and 2017. I copied this data from the web into Excel and used formulas to compute cost per unit and growth rates. Bubble charts in Mekko Graphics require the following data:
- series name--region in this chart
- X value--cost per unit
- Y value--growth in units sold
- bubble size--number of units sold
I created the appropriate spreadsheet in Excel and created the bubble chart in PowerPoint based on the selected Excel range.
Here are the formatting steps I took:
- adjusted chart margins
- adjusted x and y axis minimum, maximum and tick interval to space out the bubbles
- added axis break on the x axis to move the developed Asia bubble closer to others in the chart
- changed the reference bubble size to make all the bubbles appear larger
- added groups for emerging and developed markets to color the bubbles appropriately
- added quadrant lines to split the chart into four sections
- adjusted bubble label location and font size to improve chart appearance.
