DATA VISUALISATION

•3D•Pie Charts•Colours

RSMGAQV

3D CAN BE CHARTJUNK

•Power View does not contain 3D functionality – why?

3D OR NOT TO 3D

•Power View does not contain 3D functionality – why?•People can overestimate the vertical dimension (Wansink, 2003)•3D space makes it too difficult to compare•Values•Volumes•Areas

•Distorts

TRELLIS CHARTS

PIE CHARTS

•Power View does not contain pie charts, at the time of writing… why?•We find it difficult to read angles•We find it difficult to judge areas•We can’t easily read over 5 slices very well•Each part must be mutually exclusive

PIE CHART EXAMPLE

PIE CHART EXAMPLE

PIE CHARTS – NOT ALL BAD!

•You can compare combinations of adjacent wedges•The parts should make a sensible whole•You’re just expecting the image to answer one ‘business question’ only•You do not need trendlines

MOTION CHARTS

•This makes even more of the limited space•We can pack more information in•Data / Ink Ratio•Motion is a pre-attentive attribute•Dependent on other items e.g. chartjunk
