This tutorial guides through some of the main features of the program.
Most conveniently it is followed when the page is printed.
Start with a new worksheet, which by default holds one empty diagram.
For calculation of a simple graph enter the following:
Sinus = sin(x)
With “Sinus„ is the label of the graph, and “sin(x)„ is the term.
For calculation of the graph click into the line with the function, so that the cursor is within the function.
(Alternative: select the line with the graph with the cursor keys)
Chose from the menu "calculate" the entry "New graph"or the Toolbar button . Now the new graph appears in the diagram.

(Alternative: click on the toolbar on button (now pressed), click in the diagram to select it, click on one corner of range to be shown, hold the mouse button and drag to the other end of the range and release the mouse button. This works for zoom in and out, you can even zoom to ranges not visible now.
Change the function to
Sinus = sin(x)*5
And chose the menu entry "Update graph" from the "calculate" menu. The graph is updated..
(Alternative: Move cursor to different line and the diagram is automatically updated.)
In order to show the complete function again, selectin the menu “Diagram„ the entry "Y automatically" or the Toolbar button , so the y axis range is adjusted to the graph. This function can be activated and deactivated as it fits the needs. Similar function has the x axis Toolbar button
.
Click once again on the Toolbar button (now no longer pressed), and click in the diagram. A horizontal and vertical line appears on the position of the mouse pointer. In the status bar the value for the position of the mouse pointer is displayed and in the right field the position of the mark. Click on another diagram location in order to move the mark there.
(Alternative: move the mark with the cursor keys).
Click now on the entered function, so that the diagram is deselected, and the mark disappears.
