Trend graph: Data group
Properties in this group control the y-axis range, as well as the maximum number of data points contained in the chart. It also contains a flag that controls whether only historical data is included.
Data group properties
The group contains the following properties:
* historyOnlyFlag
* maxPointsPerTrace
* yValueMax
* yValueMin
historyOnlyFlag
When checked, the graph plots only data that is applied to the traceNValueTable properties and will ignore the timeShift property and any data that is applied to the traceNValue properties. This is useful when the same graph instance is to be used to view either historical data or historical data together with current data by setting substitutions on the display.
The default is unchecked.
This property is in the Data property group.
maxPointsPerTrace
The maximum number of data points contained in the chart. Specify a value between 2 and 30000, inclusive.
The default is 1000.
This property is in the Data property group.
yValueMax
Determines the range of the y-axis if the yAxisAutoScaleMode is set to Off. Select On for the yAxisAutoScaleMode to calculate the y-axis range according to data values being plotted. To calculate a y-axis range that always includes yValueMin and yValueMax, select On - Include Min/Max.
This property is used only if yAxisMultiRangeMode is set to Off or Classic.
