1 - About

The aspect ratio of a graph between the height and width of the axis.

The aspect ratio of a graph is an important factor for judging rate of change

For a good responsive design (ie auto-scaling), aspect ratios (like 4:3, 3:2, 16:9 etc.) must be used rather than specifying a fixed width and height.

3 - Example

Viewers can best understand changes in the slope of the line when the slope is close to:

  • 1 (45°)
  • or -1 (-45°)

By banking the shapes representing the data to near 45°, it is easier to see interesting patterns
