How to...

...add a new graph.

...remove an existing graph.

...increase the accuracy of a graph.

...export graph to a Word document.

...enter x-y data. Add a new table graph. Then you can enter your data and plot the graph.

...make the scale on X and Y equal. Set the "Equal scale of marks" option to ON (Axes page of the Document Properties dialog).

...trace a graph. Click button.

...label graphs. Click button. Then click on that place of the coordinate plane where the label should be placed. To change the properties of the existing label double click on it or click the right mouse button on the label and choose the Properties command from the popup menu. You can also delete the label with the help of this menu. 

...perform regression. Add graph of a table that should be analyzed (if it doesn't exist). Then open the Regression window with the help of the Calculus | Regression command from the main menu.

...use a calculator. Type any expression and press Enter.

...plot graph of a piecewise function. You should add several graphs with different plotting intervals and equations.
Example: Plot a graph of a piecewise function y=cos(x) when x<=0, y=1 when 0<x<=1, y=x^2 when x>1. Visible interval is [-10..10] for X and [-10..10] for Y.
1. Add a graph of Y(x)=cos(x), set its Minimum of X option to -10, Maximum of X option to 0.
2. Add a graph of Y(x)=1, set its Minimum of X option to 0, Maximum of X option to 1.
3. Add a graph of Y(x)=x^2, set its Minimum of X option to 1, Maximum of X option to 10.
You will plot the following graph:

...graph a system of inequalities. You should use the AND operator. E.g. if you want to graph the system sin(x)>xy, x^2<3y, y<4 you should plot a graph of inequality (sin(x)>xy and x^2<3y and y<4)>0.

...show background in the graph list. Set the "Show background in the graph list" option ON (Edit | Options).
