3. Set graph display screen size prior to graphing
• Press the
WINDOW
the right.
• Since the cursor pointer is positioned at " n Min", input
n Min = 0 and n Max = 10 by pressing 0 ® 10
®.
• Since Plotstart and Plotstep are the graph start point
and increment of n , input 1 ® 1 ®.
• Next, input set values for X axis (horizontal axis) and Y
axis (vertical axis).
• Press 0 ® 10 ®1 ®, set Xmin = 0,
Xmax = 10, and Xscl = 1
• Press 0 ® 50 ® 5 ®, set Ymin = 0, Ymax = 50, and Yscl = 5
* The first screen displays variables up to Xscl. Press ® to automatically open the following
screens.
4. Graphing
• Press the key to display the previous sequence
graph.
• Normally, graphs are plotted using lines. However,
graphs can also be plotted using dots or dotted lines
depending on the data you wish to graph (see CHAPTER 4 "10. Selecting a Line
Type of Graph" on page 103 for changing settings).
• Two types of variables (u to w( n -1) and u to w( n -2)) can be displayed using se-
quence graphs. When setting the two types of variables, it is necessary to input two
values for the initial values u( n Min), v( n Min) and w( n Min) (for example, when
entering 1 and 3 for u( n Min), enter "u( n Min) = {1,3}", separating numerical values
with ",").
• In the Seq graph mode, 5 types of graph formats can be selected.
• These formats can be selected by accessing the FORMAT menu. See CHAPTER 4
"7. FORMAT Setting" on page 97 for details.
• Notice on the COB-Web graph:
To trace the COB-Web graph in the sequence graph mode, it is not possible to touch
a desired point on the graph using the pen and directly move the cursor to that
position. Additionally, the display contents in the table on the split screen may vary
from those in the normal table.
