New description:
The code `plot([x,x^2],-.2,2)` is a nice shortcut for plotting both x and
x!^ 2 on the same graph. However, if you want to choose different colors
or linestyles for each function, then it seems you have to execute, e.g.,
{{{
p1=plot(x,-.2,1.2,color='blue',linestyle='dotted');
p2=plot(x^2,-.2,1.2,color='red',linestyle='dashed');
p1+p2
}}}
Here is how Maple and Mathematica handle this issue, respectively:
It seems that the keyword 'fill' allows for a dictionary input, so perhaps
the relevant code there could serve as a template?
{{{
[> plot([x, x^2], x= -.2..1.2, color=["blue", "red"],linestyle=[dot,
longdash]);
In[1]:= Plot[{x, x^2}, {x, -.2, 1.2}, PlotStyle -> {{Blue, Dotted}, {Red,
Dashed}}]
}}}
''Remarks:''
1. distinct choices for the curves should be made automatically for the
user. Running, e.g.,
{{{
In[1]:= Plot[{x, x^2}, {x, -.2, 1.2}]
}}}
in Mathematica produces two curves that are not both solid-blue.
2. the functionality for ``fillcolor``, ``color``, and ``fill`` should be
the same insofar as possible.
