For Parametric plots: the increment for the independent variable. For Polar plots: the increment value for the independent variable. For Sequence aplet: Stairstep or Cobweb types. Horizontal spacing for tickmarks. Vertical spacing for tickmarks. Those items with space for a checkmark are settings you can turn on or off. Press 3$*( _ to display the second page. Field Meaning SIMULT INV. CROSS CONNECT LABELS AXES GRID If more than one relation is being plotted, plots them simultaneously (otherwise sequentially). Cursor crosshairs invert the status of the pixels they cover. Connect the plotted points. (The Sequence aplet always connects them.) Label the axes with XRNGand YRNG values. Draw the axes. Draw grid points using XTICKand YTICK spacing. Reset plot To reset the default values for all plot settings, press >6+,)7@CLEAR in the Plot Setup view. To reset the default value settings for a field, highlight the field, and press >'(/@. Aplets and their views Exploring the graph Plot view gives you a selection of keys and menu keys to explore a graph further. The options vary from aplet to aplet. PLOT view The following table details the keys that you use to work with the graph. keys Key Meaning >6+,)7@CLEAR >9,(:6. >6+,)7@*>. >6+,)7@*A. *k. *e. 3$86(_ or >21@&217. 0(18. =220. 75$&(. *272. )&1. '()1. Erases the plot and axes. Offers additional pre-defined views for splitting the screen and for scaling (“zooming”) the axes. Moves cursor to far left or far right. Moves cursor between relations. Interrupts plotting. Continues plotting if interrupted. Turns menu-key labels on and off. When the labels are off, pressing 0(18_ turns them back on. • Pressing 0(18. once displays the full row of labels. • Pressing 0(18_ a second time removes the row of labels to display only the graph. • Pressing 0(18_ a third time displays the coordinate mode. Displays ZOOM menu list. Turns trace mode on/off. A white box appears over the (_ on 75$&(_. Opens an input form for you to enter anX (or T or N or q ) value. Enter the value and press 2._. The cursor jumps to the point on the graph that you entered. Function aplet only: Turns on menu list for root-finding functions (see “Analyse graph with FCN functions” on page 3-3. Displays the current, defining expression. Press 0(18_ to restore the menu. Aplets and their views Trace a graph You can trace along a function using the *>, or*A, key which moves the cursor along the graph. The display also shows the current coordinate position (x, y) of the cursor. Trace mode and the coordinate display are automatically set when a plot is drawn. Note: Tracing might not appear to exactly follow your plot if the resolution (in Plot Setup view) is set to Faster. This is because RES: FASTER plots in only every other column, whereas tracing always uses every column. In Function and Sequence Aplets: You can also scroll (move the cursor) left or right beyond the edge of the display window in trace mode, giving you a view of more of the plot. To move between If there is more than one relation displayed, press *k, or *e. relations to move between relations. To jump directly To jump straight to a value rather than using the Trace to a value function, use the *272_ menu key. Press *272_, then enter a value. Press 2._ to jump to the value. To turn trace on/ If the menu labels are not displayed, press 0(18_ first. off • Turn off trace mode by pressing 75$& _. • Turn on trace mode by pressing 75$&(_. • To turn the coordinate display off, press 0(18_. Zoom within a One of the menu key options is =220_. Zooming redraws the plot on a larger or smaller scale. It is a shortcut for changing graph the Plot Setup. With the Set Factors option you can specify the factors that determine the extent of zooming, and whether the zoom is centered about the cursor. ZOOM options Press =220_, select an option, and press 2._. (If =220_ is not displayed, press 0(18_.) Not all =220. options are available in all aplets. Option Meaning Center Box... Re-centers the plot around the current position of the cursor without changing the scale. Lets you draw a box to zoom in on. See “Other views for scaling and splitting the graph” on page 2-13. Aplets and their views Option Meaning (Continued) In Divides horizontal and vertical scales by the X-factor and Y-factor. For instance, if zoom factors are 4, then zooming in results in 1/4 as many units depicted per pixel. (see Set Factors) Out Multiplies horizontal and vertical scales by the X-factor and Y-factor (see Set Factors). X-Zoom In Divides horizontal scale only, using X–factor. X-Zoom Out Multiplies horizontal scale, using X–factor. Y-Zoom In Divides vertical scale only, using Y–factor. Y-Zoom Out Multiplies vertical scale only, using Y–factor. Square Changes the vertical scale to match the horizontal scale. (Use this after doing a Box Zoom, X–Zoom, or Y–Zoom.) Set Factors... Sets the X–Zoom and Y–Zoom factors for zooming. Includes option to recenter the plot before zooming. Auto Scale Rescal...
