The Graph menu (shown here) is used to select options that allow you to set up your graphs, either before or after analysis by changing signals, units, parameters, data limits, etc.
The menu items found on the Graph menu are briefly described in the table below. All of these functions are described in more detail in this manual, see the Index or Table of Con- tents to locate the references.
Table 4.2
Graph Menu Items
Menu Item Description
Spreadsheet Use this function to toggle between the spread
View sheet view and the graph view. When you display the data in spreadsheet view some menus will change and some menu items will be unavailable.
Signals Use the Signals option to access the Signal
Selection window, which allows you to choose the
X- and Y-axis signals that you want to use for your graph.
Units Use the Units option to access the Units Selec-
tion window, which allows you to choose the units
that you want to use when graphing and analyzing your data files.
Instrument Use the Instrument Parameters option to access
Parameters the DMA Instrument Parameters window or the MDSC Instrument Parameters window, which enables you to edit instrument parameters which affect the data.

Graph Menu Items
Menu Item Description
Parameters This option is only available when multiple files
Same As are open. Use the Params Same As option to copy the parameters used in another file to the current file. The parameters that are copied include the signals and units selected, graph options, baseline file (if applicable), and smoothing.
Data Limits Use the Data Limits option to select from four options: Full Range, Cursor, Time, or Tempera- ture. These allow you to use the entire data file for analysis, or to place constraints on the amount and type of data. NOTE: This option deletes any existing analyses from the plot.
Refresh Use the Refresh/Data option to redraw the plot using the current data points. Use Refresh/Plot to redraw the plot using the current data points.
X Axis Use the X Axis option to select the signal to graph on the X axis. Click on the name of the signal and the graph will be replotted immediately. This option preserves the applicable analyses when switching between these signals.
The signal specified on the Signal Selection window for the X signal is used here in addition to time and temperature.
Y Axis This option is only available when multiple Y- axis signals are displayed. Use the Y Axis option to select a Y-axis signal for functions such as rescaling, analysis, etc. Emphasis will be switched to that signal (as seen by the small box enclosing the Y-axis number).
Curve This option is only available for a curve over- lay graph. Use the Curve option to switch
between different curves on the selected axis of an overlay graph, so that you can perform functions on that curve (such as rescaling, analysis, etc.).

Graph Menu Items
Menu Item Description
Overlay Performing a curve overlay operation lets you combine curves from several different experiments or experimental techniques to provide a visual comparison of the data. This will allow you to overlay the curves on one window and position the graphs to display the data in a manner that enables you to emphasize important aspects of the data. Up to four individual y-axes may be used, containing up to ten curves, each of common units.
Plot Header Use the Plot Header option to add a text-only header to an exported or printed plot. The plot header will not be displayed on the monitor. When you select this option the Plot Header window is displayed to allow you to set up the header.
Plot Legend Use the Plot Legend option to display the Plot
Legend window, which is used to customize the
legend that will be placed on the current graph.
Inset Use this function to add a picture-in-picture
View window to the plot. When you select this option, the Inset View dialog is displayed to allow you to customize the insert view.
Options Use the Options menu item to display the Graph
(Graph) Options window. This window will enable you to
customize the axis labels, grid type, line type, color, and symbol for each curve on the graph.
Plot Full Check this option to have the data that falls
Range outside of the analysis range plotted, but grayed out. Data outside the analysis range is plotted in the "Plot Grid" color. NOTE: This option applies only to the current data file. To apply this option each time a new file is opened, check the "Plot data outside of analysis range" box found on the
Main Options—Data Page .

Graph Menu Items
Menu Item Description
Auto Scale Check this option to have the data file autoscaled
New Data when the program reads in new data for Graph/
X/Y Data Limits, Tools/Linear Transform, or a new Graph/X axis or Y axis. NOTE: This option applies only to the current data file. To apply this option each time a new file is opened, check the "Autoscale new data: x axis or y axis" box(es) found on the Main Options—Data Page .
Ignore Breaks Check this option to have the data file plotted with in Data a continuous curve, regardless of any breaks in the
data points. The data will be extrapolated to create an unbroken curve. NOTE: This option applies only to the current data file. To apply this option each time a new file is opened, check the "Ignore breaks in data" box found on the Main Op-
tions—Data Page .
Auto Refresh Check this option to automatically refresh the
Data plotted data from an active data file (real time plot) without losing completed results. Auto refesh can be turned on as a default condition on the Main
OptionsData Page.
