mode. In Explore or Experiment mode, double-click the graph. If it is not already selected, click on the 
tab.Use the Graph settings Properties Panel to view and edit the layout and appearance of graphs including the Area Graph, Pie Chart and Bar Graph. The setup for graphs is broken into three parts. This panel lets you control labeling and layout, the Graph Series Property Panel lets you set up the basic type of graph and the series that will be displayed, and the Graph Styles Tab of the Properties Panel lets you set fonts and colors. (See Getting Started Online for differences in online editing).
To view the graph's Properties Panel, click on the graph in Edit mode. In Explore or Experiment mode, double-click the graph. If it is not already selected, click on the tab.
Graphs are displayed in containers that can have a number of pages. The properties panel will open on the currently visible page, and you can navigate to other pages using the < and > buttons on the panel. Use the 
button to add a new graph page after the current page, and the 
button to remove the currently visible page. You can create as many pages you want. As you add or navigate, both the page you're on and the total number of pages will be displayed. Once you add more than one page to a graph you will also see a button 
that allows you to edit multiple pages:
Editing multiple pages will display a subset of the graph properties for all pages in the graph container. Any changes you make will be applied to all of the contained graphs.
You can reorder pages by clicking on 
and rearranging the sequence in the Reorder Pages
See Pages Styles (Interface)for more discussion of the pages.
This lets you select the options for displaying the graph.
Title is the title that will be displayed at the top of the graph.
Selection Label is the label that will be used when tabs or a dropdown is used to select different graphs. This is available only on the interface.
X Axis Title is the title that will be displayed at the bottom of the graph.
Display from ... to ... allows you to narrow the time range that will be displayed in the graph as well as set x-axis scales. Leave this blank to display everything available, or include values to display less. Any values from before the first time or after the last time specified will be ignored.
Note If you move the slider in the run tool bar to a time before the last time the values displayed will stop at the time displayed in the toolbar.
X Labels determines the number of labels that will be displayed along the X axis. Use 0 to hide the labels, or a number 2 or greater.
Y labels determines the number of labels that will be displayed along the Y axis. Use 0 to hide the labels, or a number 2 or greater.
Fill Intensity (area graphs only) determines how opaquely the area between the graph lines is filled in. Use 0 to have only the graph lines show, or 1 to have the graph lines and the fill between the lines the same color. Generally a small value such a 0.1 will work best.
Legend determines where the legend for the series identifiers will appear. Select Right, Bottom, or No Legend (to hide the legend).
Show numbers on series, if selected, will display the number 1 on the first series, 2 on the second, and so on. This can be helpful in distinguishing series when colors and line styles are not sufficiently distinct.
Include units in legend, if checked, will include the units of measurement for the variable in the legend. This option isn't available for comparative graphs, as the legend entries in that case will be run names and not variable names.
Note: The left and right axis titles under Connect Dots below are a very helpful place to put units.
Show Expand Button (interface only)
Check this to show an expand button on the graph. This will allow an interface user to make a bigger version of the graph and zoom the axis (see Expanded Graph dialog (interface only)).
Scatter Graphs
There are two additional options that appear only for Scatter graphs.
Auto Scale X Axis, if selected, will round values on the X axis to make them more readable.
Connect Points, if selected, will draw lines between the points in the scatter plot. This can be useful in making phase plots.
See Scatter Graph for more detail.
Pie Chart
There is an additional option available only for pie charts.
Label pie slices, if selected, will put labels directly onto the pie chart. This can make it easier to read the pie chart when there are a relatively small number of things being shown.
See Pie Chart for more detail.
Bubble Chart
There are addition options available only for Bubble Charts:
Min Bubble Size is the smallest size in pixels that bubbles can be. If this is set to 0 (the default) the nothing will be drawn when the z variable (see below) is less than or equal to 0.Max Bubble Size is the smallest size in pixels that bubbles can be. The best value here depends on the size of the graph. The default of 20 is appropriate for small and medium sized graphs.
Bubble Persistence lets you specify how many bubbles are drawn for each series (see below).
Show only the last bubble, if selected, will draw the values at the simulation or scrub time and nothing else.
Show ___ previous bubbles, if selected, lets you specify how many bubbles are shown. Fill in the number of bubbles in addition to the one for the current values that should be drawn. During early parts of the simulation the number of values may be limited so this is effectively the largest number of additional bubbles that will be drawn.
Show all bubbles, if checked, will display all of the available bubbles.
See Bubble Chart for more detail.
Use these entries to control the appearance of the Left and (optionally) Right axes. The right axis options are available only if you've included a series with Right Axis checked, under Series List above.
Title is the title that will be displayed next to the axis, with vertical text. If this is left blank, no title will be displayed.
Multiscale, if checked, will cause each series to be displayed with a separate scale. If this isn't checked, all series will be displayed on the same scale (though the left and right axes will always be on different scales).
Round Scale, if checked, will cause the software to use round numbers on scales to make the values easier to read. This only applies if no scale has been set for the variables (in the graph or in the scales and ranges panel for the variable).
If this option isn't checked, graphs will be displayed with a left and bottom axis only. They will be open on the top and right. If checked, you can specify the number of grid lines.
X Grid Lines specifies how many lines, including the left and right, to display. Setting this the same as X Labels in Graph Options above will create a grid line for each label.
Y Grid Lines specifies how many lines, including the top and bottom, to display. Setting this the same as Y Labels in Graph Options above will create a grid line for each label.
Sketchable options allow you to add a graphical function to the graph and have users sketch the shape of the function on the graph. See Sketchables for more information.
Graphical Function names the variable to sketch. This variable must be a Graphical Function and must have Time as its equation.
Title is the title that will appear in the legend. If left blank, the name of the graphical function will be used.
Thickness is the line thickness of the sketchable curve.
Color is the color of the sketchable curve.
