Key Features

Graph Types
Display your data as one of more than 30 different graph types in Grapher 6. 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.

•  Line and Scatter plots display data as a line or symbols. Combine line and symbols or use only the line or only symbols. Display the data as a traditional 2D line/scatter graph.

• Ribbon/wall plots are similar to line plots, but are shown with a 3D aspect!

• 3D Line/Scatter plots are used to display the location of points with three variables. Display the data as lines symbols or as lines and symbols. Add wall projections, drop lines, or labels to emphasize data on your graph!

• Step Plots display data as vertical and horizontal lines. Display your step plot as either 2D or 3D.

• Bubble Plots display data with varying sized symbols. The size of the symbol is dependent on a third variable. Change the bubble to any symbol! In Grapher 6, you can use a 2D bubble plot that displays three variables or a 3D bubble plot that shows the change in four variables. Use solid colors, gradient fill colors, multiple fill colors, or any combination of color choices to fill your bubble plots!

• Bar Charts display data as adjacent or stacked bars. Choose to have vertical or horizontal bars. Bar charts can be displayed as 2D or 3D! Use multiple colors, gradient fill colors, or a combination of color choices for bar charts. Display labels at the top of bars, at the bottom of bars, or in both locations.

• Floating Bar Charts display the difference between two variables. Choose to have vertical or horizontal bars. Choose between 2D and 3D floating bar charts!

• 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. Function plots can be shown in a 2D or 3D orientation.

• Hi-Low-Close Graphs 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 graphs are also used for many other purposes. Hi-low-close graphs can be displayed with the standard line or with bars, the 'candlestick' graph.

• Polar Graphs display 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 Function Graphs display mathematical functions. Plot radius as a function of angle, or plot a parametric equation where both the radius and the angle are a function of a third variable, T. The angle axis can be in degrees, radians or grads data.

• Polar bar charts allow direct comparison of two variables in polar coordinates. Similar to a regular bar chart, the polar bar charts allow you to determine which variable to compare against the angular axis. Display in degree, radian, or grad data.

• Rose Diagrams display degree, radian or grad data versus a radial axis. Like histograms, Rose Diagrams display statistical data, showing the number of occurrences of an event that fall within a specific angular region. Bins are fully customizable in rose diagrams!

• 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!

• 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. Display pie charts in 2D or 3D! Explode slices to emphasize a particular item!

• 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!

• Histograms display data separated into groups or bins. Add labels, a Gaussian fit, and display the Y axis as relative frequency to change the display of this graph. Display histograms as either 2D or 3D!

• Box-Whisker plots are commonly used to show the min, max, median, and lower and upper quartiles for a particular group. The caps at the end of each box indicate the extreme values (min and max).

• 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.

• Contour plots are a 2D representation of 3D data. Contour maps may either be situation on the XY plane or the XZ plane. Maps can be generated from data files or Surfer^® grid files. Choose from either a default color fill or set your own color fills!

• Surface maps use shading and color to emphasize your data features. Surface maps can be combined with any other 3D map type, to create the exact graph you desire!

Curve Fits
Curve fitting routines help depict trends in your data. Select pre-defined fits or define a custom fit to add to the graph. Display fits for Line and Scatter Graphs, Step Plots, Polar Graphs and Histograms. There are 11 pre-defined curve-fitting algorithms in Grapher:

• Linear
• Logarithmic
• Exponential
• Power
• Spline Smoothing
• Polynomial Regression
• Orthogonal Polynomial Regression
• Linear through Origin
• Running Average
• Weighted Average
• Gaussian(available only for histograms)

Associate any number of fits with a single curve. Change the line style, color and width for each fit. Applicable statistics are available for each fit. The resulting statistics are copied to the clipboard or displayed in a report window. Export fit curve data to a worksheet to calculate additional statistics. Change the range of data used to create the fit curve and the range of values to display the fit curves individually. Add confidence intervals to your fit curves to show the degree of confidence that is in the fit. Fill between confidence upper and lower bounds to highlight the certainty.

Template Graphs
Create a graph with the desired colors, number formats, tick mark spacing, legend styles, etc., and save it as a template graph for use with multiple data sets.

Project Files
Create a graph with the desired worksheet and save it as a project file. Project files save the data used inside the file. After the graph is created and saved as a project file, the external worksheet can be deleted.

Axes
Grapher has four axis scales: linear, logarithmic (base 10), natural logarithmic, and probability. Use Grapher's default settings or specify custom settings for all axis parameters. Set the axis scale, change the axis length and starting position, add additional or duplicate axes, change axis limits, enter an axis title, add grid lines, break the axis, or hide the axis on your graph. On each axis, you control the major and minor tick frequency and spacing or you can use Grapher's default settings. If the data uses date and time as one of the data columns, axis labels are automatically generated using dates and times. In addition, manual date/time labels can be created or labels can be read from a worksheet, allowing you to use any type of tick labeling.

Errors Bars
Error Bars are displayed on Line and Symbol Graphs and on Bar Charts. Display error bars for the average value, sample standard deviation, population standard deviation, or standard error of the mean. Or, calculate custom error bars in the worksheet and display them on the graph.

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 6 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.

Text Editor
Easily add text objects to graphs using Grapher's text editor. Select any typeface, font size and color for individual characters within the text block. Add superscripts, subscripts and symbols to your text. Automatically enter current dates and times. Create complex mathematical equations and include them in your graph.
