Graph Window - Overview
You can open one or more instances of Graph Window. To open
an instance of Graph Window use menu Window
-> New Graph Window in
Calc Window or in previously opened Graph Window or press Ctrl+G.
You can plot several graphs in each Graph Window. The graphs
may be specified it in one of the following analytical forms.
- A graph, specified in Cartesian coordinates in
the form F(x)
- A graph, specified in polar coordinates in
the form R(φ), where φ is the polar angle. Default
denotation for φ is fi.
- A curve specified parametrically, i.e. by a
pair of functions {x(t),y(t)}, where parameter t varies over
a certain segment. If the segment is not specified explicitly, ArtSGraph
takes [0,2π] by default.
- A set of level lines, specified in the form F(x,y)=C1,
C2, C3… In particular, F(x,y)=C can be
considered as implicit specification of a function y=y(x).
- A field of directions, given by function F(x,y).
Field of directions is represented with a set of short strokes, having
slope equal to F(x,y) at each point (x,y). This type of
graph is very useful for qualitative analysis of ordinary differential
equations, since the strokes are tangents to integral lines of equation
y’ = F(x,y)
- Broken line, specified by its vertexes (x1,y1),
(x2,y2), … (xn,yn).
Broken lines are useful for study of some numerical
calculations, such as Euler method for solving differential equations. You
also can be use broken lines to decorate other graphs. For instance you
can plot a frame. In a Broken Line you can make some segments invisible.

There are several tools which help you to manage plotting. For
instance, you can
control the size and position of the plain area
represented on a graph,
show or hide axes, specify different types of axes
marking,
change appearance of the line by specifying its color, width
and type,
determine coordinates of certain points,
copy the plotting and paste it to another application
as a bitmap,
print graphs.
