Graph Software for Scientists and Engineers

DPlot Windows software for teachers, professors, and educators to create presentation quality graphs

DPlot is a Windows application that lets educators create presentation-quality graphs from a wide variety of data sources. You don't have to be a science professor, mathematics teacher, or engineering educator to benefit from DPlot's powerful graphing capabilities.

Graphs in the Classroom

A few decades ago, hand-drawn graphs on the blackboard were sufficiently compelling to keep kids' attention in the classroom. Today's students, however, are used to seeing presentation-quality graphics in every medium, from cereal boxes to local TV news. Teachers need more sophistication in the classroom to keep their students' attention.

DPlot delivers the highest quality, most accurate graphs that are available on the Windows PC today. And by using captivating graphics in your classroom presentations and homework assignments, you can keep kids interested and motivated.

Creating Educational Graphs with DPlot

With DPlot, you can utilize data files from a wide variety of sources, and turn them into graphs of all types. DPlot easily lays out the graphs the way you want, and labels and annotates them. For added emphasis, you can use photos or images as the background for your graphs.

Multi-Dimensional Graphs for Educators

DPlot lets you graph and manipulate 1-, 2-, 3-, and 4-dimensional data. If you have a spreadsheet file or an ordinary comma-delimited file that contains statistics by year, or any groupings of figures, DPlot can grab the data, and lay it out for you in a huge variety of graphic representations.

DPlot and Excel Graphs for Teachers

The Excel add-in makes it simple to move data in a variety of layouts from Microsoft Excel to DPlot. DPlot lets you display presentation-quality graphs in a number of graph types that are simply not available in Excel, including polar charts, triangle plots, Mercator projections, and grain size distributions.

Some of your students learn well from your verbal presentations. Others can grasp numerical data more quickly if they see it displayed graphically. DPlot makes it easy to turn data into graphics, effortlessly. Sometimes you need to create stunning contour plots of 3- and 4-dimensional data. Other times, a bare-bones chart can tell your story much more effectively than words. DPlot can meet all of your graphing needs.

Graphs for All Educational Disciplines

If you're covering topics such as algebra, trigonometry, geometry, calculus, physics, or just about any science or engineering discipline, then DPlot can help you illustrate specific functions and formulas. But DPlot can enhance your students' learning of geography, civics, music, and just about any field of education.

Graphs for Students, Parents, and Principals

Students are not your only target audience. Your classroom and homework handouts are examined by parents, fellow educators, and school administrators. Impress all of your colleagues by delivering numerical information clearly, graphically.

Whether you're preparing classroom material for your students, illustrating proposals for grants, preparing your calendar-year budget for your principal, or illustrating a journal article, DPlot can help you create stronger visual images.

DPlot Makes Graphs Affordable

A single-user DPlot license costs $195(US), and will improve all of your graphs and charts now, and for years to come.

Graphing Equations

Whether you are an algebra student or teacher, DPlot will help you visualize functions easily and with beautiful results. DPlot allows you to generate curves or surfaces from equations of the form:
Along with the standard suite of trigonometric and general math functions, DPlot includes support for conditional formulas of the form if(test,if_true,if_false). And you can generate a new curve that is a function of one or more existing curves with Y=f(X,Y1,Y2,...).
Y=f(X). For a list of available functions see the Functions page.
X=f(T) & Y=g(T)
This command is especially useful for generating curves for which there is not a unique value of Y for every X, e.g. circles, ellipses, etc.
X=f(T), Y=g(T). For a list of available functions see the Functions page.
You can view 3D data in 3D (shown), 2D shaded bands or contour lines, waterfall plots or as a simple wireframe mesh. For other 3D examples see the Features page.
Z=f(X,Y). For a list of available functions see the Functions page.
DPlot's "Fill Between Curves" feature can be used to graph inequalities:
Graph of an inequality. For more information see the Graphing Inequalities page.
... and systems of inequalities:
Graph of a system of inequalities. For more information see the Graphing Systems of Inequalities page.
For more information on inequalities see the Graphing Inequalities page.

For a more complete list of DPlot features see the Features page.

... while you are at it, if you want a simple and easy to use graphing program, may I suggest DPlot, which I also use. It's a trial, and registration is cheap, and it has paid for itself many times over.
