 ``` ``` ```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. ``` ``` ``` ``` ``` ``` ``` ```Edit Properties ``` ``` ``` ```Let us make some changes to the function and change the color of ``` ```the plot. ``` ``` ``` ```You can edit all functions with the ``` ```PlotEdit ``` ```Plots... menu entry. A dialog appears ``` ```which lists all the functions that you have plotted. Notice that ``` ```&kmplot; has automatically found a unique function name for your ``` ```expressions and completed the expression to a function ``` ```equation. ``` ``` ``` ```Select f(x)=x^2 in the list. A double click ``` ```or pressing the Edit button will show you a ``` ```dialog window. Here you have access to a lot of options. Let us rename ``` ```the function and move the plot 5 units down. Change the function ``` ```equation to parabola(x)=x^2-5 ``` ``` ``` ``` ``` ```To select another color for the plot click into the ``` ```Color: box. Finally press ``` ```OK and your changes take effect in the ``` ```coordinate system. ``` ``` ``` ```All changes can be undone until you press ``` ```OK in the Edit Plots ``` ```dialog. ``` ``` ``` ``` ``` ``` ``` ``` ``` ``` ```
