DRAW
Type: Command Operation
Description: Draw Plot Command: Plots the mathematical data in the reserved variable EQ or the statistical
data in the reserved variable ΣDAT, using the specified x- and y-axis display ranges.
The plot type determines if the data in the reserved variable EQ or the data in the reserved
variable ΣDAT is plotted.
DRAW does not erase PICT before plotting; execute ERASE to do so. DRAW does not draw
axes; execute DRAX to do so.
When DRAW is executed from a program, the graphics display, which shows the resultant plot,
does not persist unless PICTURE, PVIEW (with an empty list argument), or FREEZE is
subsequently executed.
Access: …µ
DRAW
Flags: Simultaneous or Sequential Plot (–28), Curve Filling (–31)
Input/Output: None

DRAW3DMATRIX
Type: Command
Description: Draws a 3D plot from the values in a specified matrix.
The number of rows indicates the number of units along the x axis, the number of columns
indicates the number of units along the y axis, and the values in the matrix give the magnitudes
of the plotted points along the z axis. In other words, the coordinates of a plotted point are (r, c,
v) where r is the row number, c the column number and v the value in the corresponding cell of
the matrix.
You can limit the points that are plotted by specifing a minimum value (v
min
) and a maximum
value (v
max
). Values in the matrix outside this range are not plotted. If all values are included, the
total number of points plotted is r × c.
Once the plot has been drawn, you can rotate it in various ways by pressing the following keys:
™ and š rotate the plot around the x axis (in different directions)
— and ˜ rotate the plot around the y axis (in different directions)
Iand L rotate the plot around the z axis (in different directions)
