You can label points or add other annotations notes to your graph. Below is a quick-start introduction to Graphmatica. Here is a summary of common symbols. Graphmatica draws mathematical graphs, like: The equation of th best-fit-line appears at the bottom of the screen.

If you want to move the annotation later, double-click on it, click the [Place] button, then click on the graph to place that annotation. There are two ways to erase a graph.

This will squash your graph to make room for the data table. This gives better results than tracing, as tracing only finds approximate coordinates – e.


If you don’t want to see the graph, hide it. For the parabola, this also finds the vertex.

If you drew lots of graphs and erased them, they will all appear again when you open the file next graphmatifa. This forces the [Curve Fit] button to use a straight line to fit the points. Graphmatica will also graph relations implicit functionssuch as circles and conic sections.

When you start Graphmatica the first time, you might not like the layout – funny colors, small numbers. It works well for IB Math Portfolio work.

Click on the curve you want to investigate. Either change the colors of Graph1, Graph2, etc all to black, or change ggaphmatica Monochrome layout.

Then you can paste it into a document. You can also graph inequalities and it will shade in areas for you. Click on the graph of the derivative to see it’s formula at the bottom. You can also graph a line from an equation, without solving for y.

Graphmatica Quick Start

Right-click on the graph then choose: You must use Graphmatica notation to define functions, but do not use this notation when graphmatixa mathematics in an IB Portfolio. You can plot data points and ask Graphmatica to find the best-fit-line. In the formula-box, type: The pictures are smaller than you will normally see.


Now you will have white paper with colored lines, and you can draw your first graph. Before copying, you might want to resize the Graphmatica window, as resizing in a word-processor might make the picture ugly. After typing the points, you can hide the data-table again but the dots will stay. Type the coordinates of the points you want to graphmtica with graphmaatica.

Click on Draw Tangent Line, then click on a point on the curve. There are two ways to zoom in and out:
