We use Error Charts when we can display the data on a Chart of one of the basic types and we want to show the measurement uncertainty. Error Charts are usually regarded as part of a Chart, because they look like a plenty of line segments lying over the data points of the Chart with their length demonstrating these measurement errors. Basic Chart should be of Area, Bar/Column, Line or Marker type (including variations with Splines).
This example compares the prices and the prime costs of the Spring-Summer collection clothes by ACME Fashion. Each Marker point represents the information for a piece of cloth – dress, blouse or else. When you hover a point, a tooltip shows both values (the item’s price and the item’s prime cost). Note that in this sample we don’t demonstrate the extreme values of the measurement uncertainty in the tooltips, but the error bars are enabled so we can see the graphical relation between the prime costs’ and the prices’ ranges. The horizontal axis holds the prime costs values, while the prices are spread along the vertical y-axis, both in dollars.
