Sections with multiple properties appear with a plus or minus to the
left of the name. To expand a section, click on the button. To collapse a
section, click on the icon. For example, the expanded End Styles section
contains three properties: Start, End, and Scale.
The Property Manager displays the properties for selected objects. To
change a property, click on the property's value and type a new value,
scroll to a new number using the buttons, select a new value using the
slider, or select a new value from the list or palette. For
example, a polyline has Style, Color, Opacity, and Width propertiesand an
End Styles sub-section with Start, End, and Scale properties. Changing the
Color requires clicking on the current color and selecting a new color from
the color palette. Changing the Opacity requires typing a new value or
clicking on the slider bar and dragging it left or right to a new value.
Changing the Width requires typing a new number or scrolling to a new
Plot Window
A plot window is the area used for creating and modifying graphs. When
you first open Grapher, you can choose to start from an empty plot
window. Multiple plot windows can be open at one time. Click the
document tabs to easily move between multiple plot windows.
Plot Document Pages
A plot document can have multiple pages. By default a plot document is
created with a single page. Add pages to the plot document by clicking the
+ button next to the page tabs. Pages are displayed as tabs at the bottom
of the plot window. Remove pages from the plot document by clicking the
Grapher .GRF Files
Grapher .GRF files contain all of the information necessary to reproduce
the graph, except for the data. When you save a Grapher file, all the
scaling, formatting, and parameters for the graph are preserved in the file.
Grapher .GRF files save a link to the data and do not store the data
internally in the file. For example, if a .GRF file needs to be sent to a
colleague, you would need to send the data file(s) used to create the graph
in addition to the .GRF file. This format is preferred for graphs where the
data changes periodically and needs to link to the external source data file.
When opening a GRF file, the data files are reloaded into Grapher. If the
data files haven't changed, the plots will look the exact same as when they
were saved. However, if the data files have been changed, the plots will
automatically update to reflect the changes in their source data. If the data
files can't be found, Grapher will prompt you for the data files to use for
your plots.
ASCII Data
ASCII files are generic format files that can be read or produced by most
applications. There are three common ASCII data formats: .DAT, .CSV,
and .TXT. These files can also be imported into most applications, including
word processors, spreadsheets, and ASCII editors. The files differ in the
types of delimiters, or column separators, between the data. ASCII files do
not contain any worksheet formatting information such as row height,
column width, or cell formatting. This format does not have a limitation on
the number of rows or columns.
Excel Files
Microsoft Excel .XLS, .XLSX, and .XLSM files contain data and retain some
cell formatting in Grapher. Some information, such as formulas, is
ignored. Excel files can preserve all formatting information available in the
Golden Software worksheet. An Excel 2003 .XLS worksheet has a 65,536-
row limit and a 256-column limit; therefore, this format cannot be used to
store very large data sets. An Excel 2007 .XLSX worksheet has a
1,048,576 row limit and a 16,384 column limit.
