Grapher (Price: $270) A Flexible and Powerful Technical Graphing Package

graphermain.gif (11774 bytes)

Grapher is a technical graphing package designed for scientists and
engineers. Grapher gives you full control over all the graph
features to get the exact presentation you want. You can produce
line graphs, scatter plots, bar charts, function plots, and hi-low-close
graphs, and include any number of graphs and any combination of
graph types on a single page.

Graph Types

graphertypes.gif (3537 bytes)
Create many graph types quickly and easily

To portray your worksheet data quickly and easily, you can create:

line graphs
scatter plots
bar charts
function plots
hi-low-close graphs

The graph types included with Grapher let you represent your data
accurately and clearly. The number of points you can plot on a
graph is only limited by the amount of memory you have available
on your computer. Create a graph from any number of data sets,
and use optional data clipping to only display the data you want to
show on the graph. You can display symbols or data point labels on
any or all data points. You can also graph a function by typing in an
equation. By accepting the Grapher intelligent defaults you will
produce a graph in seconds. If you need to modify the graph, you
have complete control over all graph features, allowing you to
easily modify the graph to generate the presentation you want.


Grapher has three axis types: linear, logarithmic and probability.
Grapher automatically determines the axis scaling, or you can
specify all axis parameters. On each axis you have control over
major and minor tick frequency and label spacing. You can add axis
titles that include any special characters including superscripts,
subscripts and Greek characters. Use the mouse to stretch or
shrink an axis, and position the axis on the page, or specify these
parameters with exact precision by typing the values into the axis
dialog box. You can use automatic date labeling, or you can read
axis tick labels from the worksheet, allowing you to use any type of
tick labeling.

Curve Fits

Depict trends in the data with different curve fits

Curve fitting routines let you depict trends in your data. The
Grapher curve fitting algorithms include:

cubic spline
running average

With each type of fit you have control over the curve fitting
parameters. Associate any number of fits with a single curve and
display any fit over any data range. Fits can use any line attributes,
including line style, width and color. Grapher gives you fit statistics
applicable for each algorithm.

Error Bars

Stack data sets for a graphic comparison

Grapher lets you display vertical and horizontal error bars. Error
bar types include:

average value
plus and minus error
standard error of the mean
population or sample standard deviation

You can display the error bars based on values you place in the
worksheet, or let Grapher calculate the error bar values

Text Handling

You can annotate your graphs with text using any typeface, size or
color. Text can be placed at any position on the page, and be
displayed at any angle. You can embed superscripts, subscripts and
Greek characters in any text block.


Grapher includes a full-featured worksheet that allows you to
display, enter, edit and save your data. You can read data files in
many formats, including:

ASCII text

In the worksheet you can transform, sort, and calculate statistics on
your data. The number of data points the worksheet can handle is
only limited by the amount of memory you have available on your

Drawing Tools

Drawing tools let you enhance graphs by drawing objects at any
position. Create circles, squares, rectangles, polylines, polygons, or
point symbols at any location on the graph.


Templates are completed graph files that contain all the graph
parameters you might want to use to produce several graphs of the
same type. When you have several data files to display using the
same graph parameters, you can create a template graph. When the
graph is displayed, simply change the data file and the new data is
displayed using the old graph parameters. Template graphs are
especially useful when used in conjunction with the print multiple
files option discussed below.

Print Multiple Files

Grapher lets you print any number of graphs at one time. This can
be from several graphs saved on disk, or can be from a single
template graph and several data files. When printing several
completed graph files, simply specify the files to print and let
Grapher do the work for you. And with a template graph you specify
the template and all the data files you want to associate with the
template. Then Grapher prints the template graph with each of the
data files specified. After you start the multiple files printing option,
you are free to complete other tasks.
