Multi Graph
Contents
This tool facilitates the user to create and manipulate graph(s) using data columns from multiple tables. Using the Multi Graph Definition, users can create multiple graphs that suit their specific needs.
User is allowed to modify the Multi Graph Definitions, that means to create new definitions, to copy, rename and also delete existing definitions. It is also possible for the user to update, change or group graphs within a Multi Graph Definition.
To activate this tool, click on the 'Multi Graph' 
button on the Ple4Win main toolbar.
The Multi Graph Definition panel will then appear in the place of the Overview panel (a screenshot of this panel is shown below).
At this moment, no data has been added to the Multi Graph Definition. This can be led from the empty 'Curves Data' table. A default Multi Graph Definition is automatically created by Ple4Win and is called 'Default'. Multi Graph Definition is actually a collection of graphs using data from various tables in Ple4Win.
The default Multi Graph Definition 'Default' cannot be deleted.
Multi Graph is also handy to compare (results) data. For instance, to compare the calculation results of a pipeline with and without internal pressure. Data of pipeline without internal pressure could be stored in the current active project (primary database) while data of the pressurised pipeline are stored in the secondary database.
The resulted graph will be shown in the Workspace panel.
How to add graph data to Multi Graph Definition
The process of adding graphs data to Multi Graph is quite similar as adding graphs data into the Single Graph, namely: 1.Open a data table 2.Select at least 1 or more columns from this table
3.Add these data into the Multi Graph Definition using the 'Add selection to Multi Graph Definition'
4.If more graphs data are needed from other tables, just repeat steps 1 to 3 5.When finished, open the Multi Graph Definition panel to create the graphs or edit the definition to adjust the graphs. |
