Chapter 2. First Steps With KmPlot

Simple Function Plot

In the main toolbar there is a simple text box in which you can enter a function expression. Simply enter:

x^2
and press Enter. This will draw the plot of y=x^2 in the coordinate system. Enter another expression in the text box like
5*sin(x)
and another plot will be added.

Click on one of the lines you have just plotted. Now the cross hair gets the color of the plot and is attached to the plot. You can use the mouse to move the cross hair along the plot. In the status bar at the bottom of the window the coordinates of the current position is displayed. Note that if the plot touches the x-axis the root will be displayed in the status bar, too.

Click the mouse again and the cross hair will be detached from the plot.
