A history chart shows a column chart of data for a metric.
By default, it compares the actual value against the target value for each time period, and indicates whether the result is within an accepted tolerance. You can change the visible range of time periods, to increase or reduce the level of detail, by sliding the focus bar.
When you hover over a column, more detail is shown about the underlying values, including traffic lights and trend indicators. Traffic lights show the status according the performance pattern defined for a metric. For example, if the performance pattern is set to Above target is favorable, the status can be one of the following:
- Excellent performance - the actual value is equal to, or exceeds, the target value.
- Average performance - the actual value is below the target value, but is within the accepted tolerance.
- Poor performance - the actual value is below the target value, and it is below the accepted tolerance.
For more information about performance patterns, see Metric indicator dimension.
The trend indicators show whether performance improved (), declined () or remained the same () when compared to the previous time period. Where no previous time period is available, such as the initial bar in a history chart, no trend information is shown.
The following example shows a history chart that focuses on eight months of revenue data. For every month except February 2013, total revenue performance is average. With the focus on February 2013, you can see that the performance is poor, and the trend is declining when compared to January 2013.
