## Menu Items

Apart from the common &kde; menus described in the Menu chapter of the &kde; Fundamentals documentation &kmplot; has these application specific menu entries:

### The File Menu

### The Edit Menu

Edit Constants...

  Displays the Constants dialog box. See .

### The View Menu

The first three items in the menu are related to zooming.

&Ctrl;1 View Zoom In

  This tool can be operator in two different manners. To zoom in on a point on the graph, click on it. To zoom in on a specific section of the graph, hold and drag the mouse to form a rectangle, which will be the new axes ranges when the mouse button is released.

&Ctrl;2 View Zoom Out

  The tool can also be used in two different manners. To zoom out and center on a point, click on that point. To fit the existing view into a rectangle, hold and drag the mouse to form that rectangle.

View Show Sliders

  Toggles the visibility of the slider dialog. In the dialog move a slider to change the parameter of the function plot connected to it.

  Enable this on the Function tab and select one of the sliders to change the parameter value dynamically. The values vary from 0 (left) to 10 (right) by default, but can be changed in the slider dialog.

  For a small tutorial see Using Sliders.
