ZGrapher is an awards winning graphing calculator. It can plot y(x), x(y), polar, parametric and table-defined functions. All your graphs and coordinate space may be fully customized. You can comment your graphs using labels and legend.

For a few seconds you can obtain derivatives, tangents, normals and calculate integrals. Regression analysis will help you to find trend of your data. Results of your work may be exported to Word or saved as BMP, GIF and PCX pictures.


Supported graph types:

  1. Y(x);
  2. X(y);
  3. graphs of tables;
  4. R(a) - in polar coordinates;
  5. X(t) and Y(t) - parametrical equations;

You can specify color, style and width of lines for each graph. You can also change additional properties of graphs depending on graph type (e.g. amount of plotting points, plotting intervals, etc). The amount of graphs in one document is limited only by the amount of the free memory.

Calculus features:

  1. analytical derivation;
  2. numerical integration;
  3. obtaining equations of tangents and normals.

Lots of design parameters of a coordinate plane (parameters of axes, grid, background, legend). You can place custom text labels and points on the coordinate plane. Coefficients on axes. You can copy graphs as BMP to export them to the Word documents and save graphs as BMP.

What's New:

  • New features: regression analysis, GIF and PCX image formats support
