Decimal Rescales both axes so each pixel = 0.1 units. Resets default values for XRNG (–6.5 to 6.5) and YRNG (–3.1 to 3.2). (Not in Sequence or Statistics aplets.) Integer Rescales horizontal axis only, making each pixel =1 unit. (Not available in Sequence or Statistics aplets.) Trig Rescales horizontal axis so 1 pixel = ./24 radians, 7.58, or 81/3 grads; rescales vertical axis so 1 pixel = 0.1 unit. (Not in Sequence or Statistics aplets.) Aplets and their views Option Meaning (Continued) Un-zoom Returns the display to the previous zoom, or if there has been only one zoom, un-zoom displays the graph with the original plot settings. ZOOM examples The following screens show the effects of zooming options on a plot of 3sinx . Plot of Zoom In: In 3xsin Un-zoom: Zoom Out: Un-zoom Note: Press to move to the bottom of the Zoom list. Out Now un-zoom. X-Zoom In: X-Zoom In Now un-zoom. Aplets and their views X-Zoom Out: X-Zoom Out Now un-zoom. Y-Zoom In: Y-Zoom In Now un-zoom. Y-Zoom Out: Y-Zoom Out Zoom Square: Square To box zoom The Box Zoom option lets you draw a box around the area you want to zoom in on by selecting the endpoints of one diagonal of the zoom rectangle. 1. If necessary, press to turn on the menu-key labels. 2. Press and select Box... 3. Position the cursor on one corner of the rectangle. Press . 4. Use the cursor keys ( , etc.) to drag to the opposite corner. Aplets and their views 5. Press to zoom in on the boxed area. To set zoom factors 1. In the Plot view, press . 2. Press . 3. Select Set Factors... and press . 4. Enter the zoom factors. There is one zoom factor for the horizontal scale (XZOOM) and one for the vertical scale (YZOOM). Zooming out multiplies the scale by the factor, so that a greater scale distance appears on the screen. Zooming in divides the scale by the factor, so that a shorter scale distance appears on the screen. Aplets and their views Other views for scaling and splitting the graph The preset viewing options menu ( ) contains options for drawing the plot using certain pre-defined configurations. This is a shortcut for changing Plot view settings. For instance, if you have defined a trigonometric function, then you could select Trigto plot your function on a trigonometric scale. It also contains split-screen options. In certain aplets, for example those that you download from the world wide web, the preset viewing options menu can also contain options that relate to the aplet. VIEWS menu Press , select an option, and press . options Option Meaning Plot-Splits the screen into the plot and a Detail close-up. Plot-Table Splits the screen into the plot and the data table. Overlay Plots the current expression(s) Plot without erasing any pre-existing plot(s). Auto Scale Rescales the vertical axis so that the display shows a representative piece of the plot, for the supplied x axis settings. (For Sequence and Statistics aplets, autoscaling rescales both axes.) The autoscale process uses the first selected function only to determine the best scale to use. Decimal Rescales both axes so each pixel = 0.1 unit. Resets default values for XRNG (–6.5 to 6.5) and YRNG (–3.1 to 3.2). (Not in Sequence or Statistics aplets.) Integer Rescales horizontal axis only, making each pixel=1 unit. (Not available in Sequence or Statistics aplets.) Aplets and their views Option Meaning (Continued) Trig Rescales horizontal axis so 1 pixel=./24 radian, 7.58, or 81/3 grads; rescales vertical axis so 1 pixel = 0.1 unit. (Not in Sequence or Statistics aplets.) Split the screen The Plot-Detail view can give you two simultaneous views of the plot. 1. Press . Select Plot-Detail and press . The graph is plotted twice. You can now zoom in on the right side. 2. Press , select the zoom method and press or . This zooms the right side. Here is an example of split screen with Zoom In. – The Plot menu keys are available as for the full plot (for tracing, coordinate display, equation display, and so on). – moves the leftmost cursor to the screen’s left edge and moves the rightmost cursor to the screen’s right edge. – The menu key copies the right plot to the left plot. 3. To un-split the screen, press . The left side takes over the whole screen. The Plot-Table view gives you two simultaneous views of the plot. 1. Press . Select Plot-Table and press . The screen displays the plot on the left side and a table of numbers on the right side. Aplets and their views 2. To move up and down the table, use the and cursor keys. These keys move the tra.ce point left or right along the plot, and in the table, the corresponding values are highlighted. 3. To move between functions, use the and cursor keys to move the cursor from one graph to another. 4. To return to a full Numeric (or Plot) view, press (or ). Overlay plots If you want to plot over an existing plot without erasing that plot, then use Overlay Plot instead of . Note that tracing follows only the current functions from the current aplet.
