<description>
<p>
ZeGrapher is an ergonomic, intuitive and fast software for plotting
mathematical objects (functions, sequences, parametric equations)
and experimental data on the plane (with polynomial fitting, CSV
import/export).
</p>
<p>
Here is what Zegrapher v3.0 can offer you:<br/>
<ul>
<li>Visualize up to six functions simultaneously. All the usual functions can be called: they're all written on a virtual keyboard. <br/>
On a given function, others can be called, so it is possible to associate or compose functions.</li>
<li>Numerical sequence plotting, they can be defined by a recurrent relation or explicitly.</li>
<li>Parametric equation plotting. The curves can be animated, with adjustable smoothness (frame rate) and speed (ms per step).</li>
<li>Experimental data plot and polynomial fit (regression). Data can be imported/exported from a CSV file.
<li>Parametric plot for functions, sequences and parametric equations: the parameter symbol to use is "k".</li>
<li>Plot tangents: they can be moved and resized simply with the mouse.</li>
<li>Plot derivatives and antiderviatives.</li>
<li>Print the graph, with the following options :</li>
<ul>
<li>Choose the size and the position of the graph on the sheet.</li>
<li>Print in color or gray-scale.</li>
<li>Export on a PDF file.</li>
</ul>
<li>Export to all common image formats (png, jpeg, tiff, gif...).</li>
<li>Display a table of values with different options.</li>
<li>Navigate on the graph :</li>
<ul>
<li>Select a curve to display the coordinates of its points.</li>
<li>Zoom/unzoom on each axis separately or together, with the mouse on a point, or on a rectangular region.</li>
<li>Move the graph.</li>
</ul>
<li>Customize the presentation :</li>
<ul>
<li>Change all the colors: axes, background, functions...</li>
<li>Chose the program's and graph's font</li>
<li>Adjust the plotting precision. Note that it will also affect rendering speed.</li>
<li>Show/hide a grid.</li>
<li>Activate/deactivate curves' smoothing.</li>
<li>Plot the graph on an orthonormal basis.</li>
</ul>
</li>
</ul>
