return to gGraph® Manual


A gGraph Folio contains one or more graph pages, each of which can contain one or more graphs. Each graph can have from zero to essentially limitless plots. The main menu for each Folio allows the user to:

Create “New” graphs and graph pages in the Folio and to copy existing graphs (“Graph as copy”) within a Folio or between Folios

“Delete” graphs and graph pages from the Folio

“Save” the Folio (as a .ggf file)

Save the Folio with a new name using “Save as”

“Close” the Folio

The remaining menu items on the main menu for each Folio allow manipulation of a particular graph. A graph is made available for manipulation either by creating a new graph (e.g., see Quick Guide to Making a Graph above) or by opening an existing Folio that contains a graph(s). After select the correct graph page by clicking on the appropriate tab, the desired graph is selected either by right-clicking on the graph or by clicking the selection box on the right margin of the graph. Right-clicking of the graph causes the selection box to be checked. All operations under the “X axis Properties”, “Y axis Properties”, “Labels and Lines” and “Plots” menu items will be carried out on the selected graph(whether it is currentlly visible or not).

X (or Y) axis Properties:
Label: The text, font, size, color, style and position of the axis label can be changed (see also VII below).

Axis: The thickness and color of the axes can be changed

Scale: The axis scale type (linear or log) as well as the maximum and minimum values for the axis can be changed

Major ticks: The label (format, font, size, color and style), spacing, length, thickness and color can be adjusted

Minor ticks: Length, thickness, color and number of minor ticks can be selected

Labels and Lines:
Add Text Label: Selection of this menu item adds a generic text label to the currently selected graph at a default location. When a label is selected its background is off-white. Select the graph outside of the label to deselected the label. The label can be moved by left-click and drag. Right-clicking on the label opens a context menu that allows the user to copy the label, delete the label and change the label text (see also VII below), font, size, color and style as well as bring the label to the front.

Add Line: Selection of this menu item adds a generic line to the currently selected graph at a default location. The label can be moved by left-click and drag and re-sized by left-clicking and dragging the grip. Right-clicking the line opens a context menu that allows the use to copy the line, delete the line, set the arrow end cap and arrow start cap size, set the line width, color, dash style and dash values (for custom dash style). Simultaneous right- and left-click with dragging (right to left or left to right) rotates the line/arrow.

Special note about lines/arrows: Some actions (e.g., “Refresh Plot”) may cause lines/arrows to disappear temporarily. Running the mouse over the location of the lines/arrows will cause them to reappear. This is a known bug.

Copy: Selection of this menu item will place a copy of the currently selected label or line on the clipboard.

Paste: Selection of this menu time will copy the label or line currently on the clipboard to the currently activated graph. This allows labels and lines to be copied from graph to graph within or between Folios.

Refresh: Selection of this menu item refreshes the plots in the currently active graph. “Refeshing” is necessary when changes are made to a data file or a datagrid that the user wishes to propagate to the graph. A known bug is that “Refreshing” results in lines/arrows disappearing behind the graph. Running the mouse over the graph will cause lines/arrows to reappear.

New: Selection of this menu item allows the user to make new plots or change existing plots on the currently active graph. Selecting “New” causes the datagrid selection window to appear.

The datagrid selection window gives a list of currently open datagrids (bottom section). These grids are either created from scratch or imported from existing .xlsx data files. This window allows the user to open (import) additional data files and refresh the datagrid list (necessary if a data file is opened/imported from the “Data File” menu item of the main menu. The user can cancel adding plots (causing the datagrid selection window to close), and refresh plots (see above).

Clicking one of open datagrids (bottom of the datagrid selection window) causes a plot selection window to open. The user chooses one “x” column and one or more “y” columns from the columns in the datagrid. If plots employing the chosen “x” column already exist on the current graph, the previously selected “y” columns will populate automatically. These can be deselected to remove the corresponding plot(s). All plots with the selected “x” column can be deleted by clicking the “Clear” button. Changes are committed by clicking the Add/Update button. All changes are discarded by pressing the “Close” button.

One of the powerful features of gGraph is the ability to add plots from multiple data files to the same graph. For an existing (activated) graph, simply select “New” under the “Plots” menu item, chose the name of the new data file in the datagrid selection window that you wish to import, chose the corresponding datagrid from the list at the bottom of the selection window, and add the desired plot(s) to the graph.

Open Plot Properties: This menu item opens a table providing information about each of the plots in the currently selected graph. This information includes: The name of the plot (as it also appears in the figure/graph legend), a check box to delete the plot (upon selection of the “Refresh” menu item described above), a check box indicating where the plot is to be shown in the figure legend, the symbol for the plot, the line for the plot, the data file containing the data for the plot, and the name of the “x” and “y” data column used to construct the plot. The following actions are available by clicking or right-clicking these entries for the plot:

Plot Name (click): The user can change the text (see VII below), font, size, color and style of the plot name (also changes the figure caption) and can change the position of the plot name in the figure legend.

Delete Plot (select): Deletes the plot from the graph when the “Refresh” menu item is selected or the Plot Properties table is closed.

Show in Legend (select/deselect): Determines if the plot name, symbol and line are shown in the figure legend. Changes are implemented when the “Refresh” menu item is selected or the Plot Properties table is closed.

Symbol (click): The user can change the symbol, its size, color, line width and line color, and plotting frequency. Choosing a symbol style of “none” eliminates symbols from the plot.

Line (click): The user can chose line/no line, the line width, color, style and custom dash pattern.

Close Plot Properties: This menu item closes the Plot Properties table for the selected graph.

Legend: The user can choose to show/hide the figure legend and to display the legend with or without a border.
