Multi Graph

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' TmainMGraph button on the Ple4Win main toolbar.

Multi Graphs Show Button On Toolbar

The Multi Graph Definition panel will then appear in the place of the Overview panel (a screenshot of this panel is shown below).

Multi Graphs Definition Empty

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.

Warning 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.

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

Info Columns can be selected by clicking, Shift+clicking and/or Ctrl+clicking.

Info With a node/element based table the node/element values will be on the X-axis. For other tables at least 2 columns should be selected. The first selected column will become the x-axis, data from all other columns are treated as y-values.

3.Add these data into the Multi Graph Definition using the 'Add selection to Multi Graph Definition' TtblSMgraph button (on the toolbar of the data table)

Info Unlike the Single Graph, data that compose the Multi Graph may come from various tables, even from the secondary database.

Warning Before adding graphs data to a Multi Graph Definition, make sure that the correct definition has been selected. If no definition has been selected yet, Multi Graph Definition 'Default' will be used instead.

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.

Click to expand/collapse        How to add graph data from Secondary database to Multi Graph Definition

Info This functionality is available, only if a secondary database has been defined.

1.Open a data table
2.Select at least 1 or more columns from this table

Info Columns can be selected by clicking, Shift+clicking and/or Ctrl+clicking.

Info With a node/element based table the node/element values will be on the X-axis. For other tables at least 2 columns should be selected. The first selected column will become the x-axis, data from all other columns are treated as y-values.

3.Add these data into the Multi Graph Definition using the 'Add selection from secondary database to Multi Graph Definition' TtblSMgraph2 button (on the toolbar of the data table)

Warning Before adding graphs data to a Multi Graph Definition, make sure that the correct definition has been selected. If no definition has been selected yet, Multi Graph Definition 'Default' will be used instead.

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.

Info If you want to compare (result) data between 2 projects, make sure you select the same columns from the same data table from both projects.
