BarGraphData

A BarChart can be configured in different ways:

Via Engineering

Array of numbers
Array of arrays of numbers

Via an array from the PLC

Array of Numbers
aValues: ARRAY [1..10] OF INT;
Array of arrays of numbers
aValues: ARRAY [1..2, 1..10] OF INT;

Engineering

1. Add a bar chart to the interface.

2. Define which type of object you want to use.

Array of numbers (Array<number>):

3. Define the number of members of the array and their values for the 'Bar Graph Data' attribute of the 'Common' category using the 'Bar Graph Data' dialog.

Array of arrays of numbers (Array<Array<number>>)

3. Define the number of data sets of the array for the 'Bar Graph Data' attribute of the 'Common' category using the 'Bar Graph Data' dialog.

4. Define the number of members of the array and their values using the 'Bar Graph Data' dialog.

Items	List of all objects added
	Delete the selected object
	Change the object order (top = left)
	Add a new object

If you have selected the data structure 'Array<Array<number>>', you can first define different arrays, each representing a bar graph.

Name	Description
Array	Definition of an array of numbers representing a data set to be displayed as a bar graph

Each of these arrays has entries that you can define using the second version of the dialog. If you use the data structure 'Array<number>', this dialog is offered directly.

Name	Description
Number	Definition of a value from a data set to be displayed as a bar graph

PLC

1. Add a bar chart to the interface.

2. Link the array to the 'Bar Graph Data' attribute of the 'Common' category.
