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.

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 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.

Polar bar charts are bars that are displayed using radius and angle values in a worksheet. The bar is shown at the length (radius) indicated in the worksheet cell. Alter line colors, fill colors, or bar width. Bar charts can be stacked or adjacent, when multiple data exists for each value.

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!

Display polar wind charts using class colors. 
The stacked classes reveal the total distribution in each wind direction.

Polar Graph Features

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!

What's New in Grapher^™ 8?

After compiling a list of the new features in Grapher 8, we chose a small sample of these new features to display here. Of course, these are only a few of the many features available in Grapher 8!

New Graph Type!

Transparency!

Magnifiers can be added to show graph items in an enlarged view. When using a graph magnifier, the magnifier has new axes that can be controlled independently from the whole graph! Move the magnifier to any location in your graph or anywhere on the page. 

Change the axis properties inside the magnifier! Zoom in on any area in your graph!

Drawing insets work similar to graph magnifiers, except that all items on the page are magnified, including text, drawn objects, and images. In addition, graph types that cannot be used to create a graph magnifier can be enlarged with a drawing inset zoom. All properties of the inset zoom can be altered, to fit your needs.

Add an inset zoom to show drawn objects small portions of graphs.

Limit your Ternary Graph to any portion of the whole!

Limit your ternary diagram to any section of the plot that you desire! Is all your data in one area of the graph? Zoom in on the section using the dynamic ternary resizers to display only that area!

Change limits on a ternary graph to zoom in on the desired area!

Often you have information in your worksheet that needs to be displayed on your graph. Now, there is a quick and easy way to add text to your graph directly from your worksheet cell. When the worksheet changes, so does the graph!  Now, all text blocks can be linked to a worksheet, including axis titles, graph titles, headers and footers!

Easy Legend Customizations!

Legends have been significantly updated in Grapher 8. You can add link any portion of the legend to a worksheet cell. You can show labels on the left or right. You can have multiple columns. You can set the distance between the title, the rows, and the columns separately. You can also display the fill color under the curve.

Display your legend however you desire!

LSometimes, you need a different color line to emphasize data in a particular section of your graph. Grapher 8 has made creating this emphasized section easier than ever! Simply include the color definition in the worksheet. The graph can then use this worksheet column for both the line and symbol color.

Use different colors for different section of your plot.
Have the line color different or the line and symbol color. 

More compatibility with non-US formats!

Grapher 8 has added an easy way to show commas as decimal separators or periods as thousands separators.

Set the decimal comma and the thousands
delimiter in the Label Format dialog.

Easily create just the color you want! Choose from a standard palette of colors, select to match any color on the screen, or easily create custom colors!

Select the exact color and shade you want!

• Digitizing from a ternary plot gives 3 normalized values.
