**Linear Graphs**

__Linear Graphs__
All graph types in Grapher give you full control over all graph parameters. Combine multiple graph types to present your data in a completely new way! Alter any property of any of the graph types to create compelling new graphs. You can accept the Grapher intelligent defaults to automatically create a plot, or click any aspect of the graph to easily customize those features.

Line, Scatter, and Line/Scatter plots display data as a line, as symbols, or as a combination of line and symbols. Alter line colors, symbols colors, or fill between curves.

Line/scatter plots can have multiple axes and curves.
You can change line properties for individual curves or fill curves.

Class scatter plots allow symbols to be based on a range of data values in a worksheet column. In addition to class scatter plots, regular symbol plots can be created with different symbols based on information in a column or in a symbol table.

Class scatter plots have variable symbols with separate properties. Symbol size, shape, and color can change depending on the value in your class column in your worksheet.

Function Plots display mathematical functions. Plot Y as a function of X, or plot a parametric equation where X and Y are a function of a third variable, T.

Specify a function or equation to create a graph. Position the axes anywhere on the page.
Break axes to reveal interesting trends in your data.

Step Plots display linear data in a similar manner to line/scatter plots. Except, with step plots, connecting lines are only vertical and horizontal. All other parts of the plot are editable exactly like the line/scatter plot.

Legends and graph titles can add informative information to any graph!

Display line/scatter plots over any axis range, using the default full axis range or specifying only the section you want to display on the graph. And with Grapher you can add color fill between plots to produce dazzling displays of your data.

**Bar Type Graphs**

__Bar Type Graphs__
Bar type graphs display data as boxes, cones, spindles, diamonds, or as an image. All bar type graphs can be displayed either horizontally or vertically. As with all graph types in Grapher, you have full control over all graph parameters. Bar charts are made from XY data in a worksheet. The bar is shown at the height indicated in the worksheet cell. Alter line colors, fill colors, orientation, or bar chart shapes. Bar charts can be stacked or adjacent, when multiple data exists for each value.

Bar charts can be filled with different colors, display labels, or be variable widths,
depending on your needs and preferences! Floating bar charts display similar data except that the bar has both a minimum and maximum defined in the worksheet. All settings can be changed in a manner similar to bar charts.

Display horizontal or vertical bars! Add text labels, overlay multiple bars, or use dates –
whatever you want to display; Grapher has a way to make your data stand out! Histograms display data in groups or bins. Each bin represents a range of values on the X axis. The height of a bin represents the number of data points that fall within that bin’s range. Histograms can display data as a count or as a relative frequency.

Use an image fill to make your graph more exciting!
Add legends, labels, and fit curves to more accurately represent your data.

__Bar Type Graph Features __

**Polar Plots**

__Polar Plots
__
Polar plots display data on polar coordinates, using degree, radian, or grad data versus a radial distance. The degree, radian or grad data are displayed on a circular angle axis. The second axis is a radial axis showing the distance from the center of the circle. Polar plots can display mathematical functions, line/scatter data, bars, or classed scatter plots. As with all graph types in Grapher, you have complete control over all aspects of the graph.

Polar line/scatter plots display data as a line, as symbols, or as a combination of line and symbols. Alter line colors, symbols colors, or add labels.

Polar line/scatter plots can use the same symbol or varied symbols for point locations.
Add lines connecting the points or display only the symbols.

Polar class scatter plots allow symbols to be based on a range of data values in a worksheet column. In addition to class scatter plots, regular symbol plots can be created with different symbols based on information in a column or in a symbol table.

Display classes with different colors or shapes. Limit your points to inside the polar area
or allow points to go outside the area. Use text labels for axes for clarity.

Display classes with different colors or shapes. Limit your points to inside the polar area
or allow points to go outside the area. Use text labels for axes for clarity.

Stacked polar bar charts allow comparison of multiple sets of data on polar axes.

Polar function plots are lines, symbols, or both that display a mathematical function in polar coordinates

Create multiple plots on the same graph and add colors to differentiate between each curve.

Radar graphs, also known as spider plots, are new in Grapher 8! The radar plot has a similar appearance to other radial graphs, except there are multiple radial axes and no angle axis. A radar graph is a graphical method of displaying multiple variables. Comparisons between multiple radar plots typically show trends in your data.

Radar plots have an additional axis for each new variable. Display multiple data sets on the same graph,
overlaying the plots, and filling with a partial transparency to see all the options.

Rose diagrams display statistical data like a histogram, showing the number of occurrences of an event that fall within a specific angular region. Bins are fully customizable in rose diagrams!

Show unidirectional or bidirectional data on a rose diagram.

Wind Charts graph frequency vs. wind direction. Bins are created according to the wind speed. The frequency can be viewed as counts, relative frequency, or as percentages of relative frequency. Bins are fully customizable!

__Specialty Graphs__
Specialty graph include graphs such as box-whisker plots, ternary diagrams, or stiff diagrams. Each graph has its own rules and displays in a completely unique way. As with all graph types in Grapher, you have complete control over all aspects of the graph.

Box and whisker plots display statistical data. Each column is assigned to a box. The box top-bottom values are defined by the 25th percentile and 75th percentile. The whiskers are the minimum and maximum values, unless outliers are defined. Then, the whiskers can be changed with an outlier definition. Box and whisker plots allow complete control of all line colors and styles, symbol colors and shapes, and fill colors.

Display outliers on a box-whisker plot as symbols or as whisker lines.
Compare multiple sets and change the properties of each.

Bubble plots display three variables on two axes. The third variable is shown in the size of the bubble. All aspects of the plot can be changed, including the bubble symbol, line properties, and whether labels are shown.

Bubble plots display variable symbol sizes, based on data in a column.
Axes display with multiple options such as dates or reverse direction.

Hi-Low-Close plots display a range of Y values at each X value. These plots are commonly used to display the high, low, opening and closing of stock values, though Hi-Low-Close plots are also used for many other purposes. Hi-low-close graphs can be displayed with the standard line or with bars, the "candlestick" graph.

Display multiple axes and multiple graphs on each page.
Add a graph magnifier to highlight a subset of your data.

Pie Charts show data as proportional slices of a circle. Each data value is divided by the sum of the data to determine the size of the slice. Explode slices to emphasis a particular item! Change the property of each slice individually

Pie charts can show multiple slices, with full customization of each slice,
including labels, fill color, and explosion factor.

Stiff diagrams can be used to display water quality. Stiff diagrams show relative concentrations of multiple cations and anions.

Stiff plots can be color filled to aid in the interpretation of the graph.

Ternary diagrams show the relative proportions of three variables on three axes. Choose to show the relative proportions as percentages or as fractions. Add lines to connect the points on the ternary diagram! Display any column for the labels or show relative proportions for labels! Zoom in on an area of interest!

Zoom in on a section of a ternary diagram to reveal more detail!

Vector plots are used to show the starting and ending point of a variable, such as wind or current. Grapher allows you to set the starting XY position. The ending position can be specified with angle and magnitude or ending XY position.

Add line/scatter base maps to add locations to your vector maps!

**Managers and Inspectors**

__Managers and Inspectors__

Use the object manager to easily
select, arrange, or delete
the objects in your graph.

The object manager makes the editing of any object simple. It displays all the objects in the plot document in an easy-to-use hierarchical list of objects. The objects can be selected, arranged, removed, and renamed in the object manager.

When an object is selected in the object manager, it is also selected in the plot window. Changes made in one location are automatically reflected in the other. Select multiple objects at one time to make editing even faster!

Click and drag objects in the object manager to change the drawing order in the graph.

Make changes to the graph in the property inspector and
the graph automatically updates to show the change.

When an object is selected in the object manager, changes to the object can be made in the property inspector. The property inspector is a docked window that is always displayed on the screen. You can make the property inspector floating or close it, if you do not want it to display. All of the properties for an object are listed in the property inspector. For instance, in the Graph 3 selected in the above object manager, you may want to change the background color or style. Once the object is selected, the change can be made immediately in the property inspector. The change automatically updates the graph.

**Labels**

__Labels and Curve Filling__

Labels can be added to most graph types. All properties of the labels can be changed easily, including numeric format, adding bold or italics, changing the font size or style, or changing the label color. In addition, labels can be moved so that neighboring labels do not overlap. Grapher adds the ability to quickly move labels for most graph types with the mouse. Select only the label you want to move and effortlessly drag it to a new location. Labels can also be moved with the keyboard for finer adjustments.

Most graph types also support curve filling. Fill can be defined between two curves or by using a single curve. With a single curve, fill above, below, to the left, or to the right of the curve. Choose to fill to the axis minimum or maximum or to a customized data value.
