Grapher 10

ScreenshotThis easy-to-use, powerful and dynamic program will have you creating publication-quality graphs in minutes. The superior, professional, impressive graphs will be wowing your audience every time they see your graphs.

Features of Grapher

Curve Fitting

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)


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.

Date and Time Compatibility

Use date and time entries in the worksheet as a data column in Grapher 5. Grapher will automatically use date and time labels on the axis. Clip the curve, limit the axis minimum and maximum using date and time values. Set axis tick marks based on a calendar frequency such as once per month, twice per year, or once per every four hours.

Error 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.

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 customised 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.

Other Features

  • Set multiple levels of undo.

  • Add legends to graphs.

  • Control line styles, color and width.

  • Add drawing objects to any graph such as points, lines, polygons, rectangles and ellipses.

  • Create custom colors, lines, and fill patterns.

  • Reshape polylines and polygons using the reshape tool.

  • Combine and break apart composite objects.

  • Rotate all drawn objects, imported objects and graphs.

  • Lock the position of any object to prevent accidental movements.

  • Use the Arrange command to move objects forwards or backwards.

  • Add a variety of arrows to the ends of polylines.

  • Digitise data from a graph using a large crosshair that extends to the rulers. Write the data to an ASCII file to create new graphs.

  • Fix the digitising process directly to the line or digitise anywhere in the plot window.

  • Display and edit detailed areas of a graph using the Zoom commands.

  • Calculate the area under a curve.

  • Switch between two different plot types. For example, change your line plot into a bar chart. 

Worksheet Features

  • Display, enter, edit, print and save data.

  • Double precision capabilities allow up to 15 digits without loss of precision.

  • Import data files in the following formats: XLS, DBF, MDB, SLK, WKx, WRx, CSV, TXT, DAT, BNA, and BLN.

  • Save your data files in XLS, SLK, CSV, TXT, DAT, BNA, and BLN formats.

  • Cell formatting includes background colors and cell height and width.

  • Include formatting information when copying to the worksheet.

  • Sort data using multiple columns.

  • Calculate numerous statistical functions on individual columns of data.

  • The number of data points the worksheet can handle is only limited by the amount of memory available on your computer (up to 1 billion rows x 1 billion columns).

  • View a list of all worksheets associated with a graph.

  • Export data from fit curves, function plots, histograms, rose diagrams, and wind charts to create new data files.

  • Update command allows worksheets that are edited in other programs to update immediately in Grapher.

  • Embedded Excel window allows the use of Microsoft Excel from within Grapher.

  • Create mathematical transforms on columns, rows, or individual cells.

  • Search, find, and replace values throughout the worksheet.
