Note: There is a limit of variables that can be added to the graph. This limit is device
specific. On the bottom of the dialog the limit is shown and how much variables can be
added.
Note: Adding many variables might make the graph confusing.
After a variable was added, the following options can be set for each variable:
Name
The Name of the variable. This can't be edited here.
Min Value
The minimum value for the variable that shall be used for the graph. This defines the lowest
value of the Y axis and together with Max Value the range of the Y axis.
If Show Value Labels at Y Axis is enabled, the value of Min Value will be shown at the
bottom of the Y axis.
Min Value will not be considered if Auto Fit Y Axis is enabled.
Default value: Configured minimum value of the selected variable
Possible values: Any integer value that is less than Max Value
MaxValue
The maximum value for the variable that shall be used for the graph. This defines the
highest value of the Y axis and together with Min Value the range of the Y axis.
If Show Value Labels at Y Axis is enabled, the value of Max Value will be shown at the top
of the Y axis.
Max Value will not be considered if Auto Fit Y Axis is enabled.
Default value: Configured maximum value of the selected variable
Possible values: Any integer value that is greater than Min Value
Auto Fit Y Axis
If this property is disabled, the value range of the Y axis for this variable is fixed from Min
Value to Max Value.
If this property is enabled, the graph will automatically calculate the range of the Y axis
based on all values of the variable currently visible in the graph. Min and Max Value will not
be considered.
Default value: Disabled
Possible values: Disabled or Enabled
Line Attribute
To change the look of the value line that is drawn for this variable, a line attribute object can
be selected here. Line width, color and line pattern can be defined.
Each variable should get a different line attribute so that they can be distinguished in the
graph.
Default value: Solid Black
Possible values: Any line attribute object defined in the project properties.
Number of Samples to Record
To improve performance, the number of value changes that are recorded by the graph can
be limited. This should be done especially if no long history is required (e.g. only the latest
100 values are of interest).
As soon as the number of samples are reached during run time, the oldest values recorded
will be deleted.
Default value: 10000
