Limitations of graphs

When creating graphs, keep the following limitations in mind:

• No more than twelve attributes can be displayed on a graph. 
• No more than two measurement types can be displayed on a graph. 
• For example, if two statistics are measured in percentage and two in units, then all four appear in the graph because Y1 or Y2 allows a graph to have two like-measurements each. 
• However, if you have three statistics, one being measured in percentage, another being measured in units, and yet another being measured in time, an error message appears (as shown below), and the graph is not displayed. 
• When choosing any indicator, only one attribute can be selected because the indicator cannot relate to more than one measurement. 
• Graph displays NO_DATA image when there is no data available for the total graph period.

• A pie graph displays a blank screen if all the data is out of schedule for the selected time period.
