Draw one function, varying color by (gradient) using another function's value
I'm trying to draw something in TikZ where I want to vary the draw color.
E.g. I'm drawing this line
documentclass[tikz]{standalone}
usetikzlibrary{intersections}
begin{document}
begin{tikzpicture}
draw plot[variable=x, samples=100,domain=-10:10] ({x},{sin(deg(x))+0.6*x});
end{tikzpicture}
end{document}
But now I want the color to indicate the value of a function, e.g. c = x2.
Edit:
With x2 this could then look like:
tikz-pgf color

Something like this may be:
documentclass[tikz]{standalone}
usepackage{pgfplots}
begin{document}
begin{tikzpicture}
begin{axis}
addplot [mesh, variable=x, samples=100,domain=-10:10] ({x},{sin(deg(x))+0.6*x});
end{axis}
end{tikzpicture}
end{document}
I just changed the draw environment with addplot within an axis environment. This will give you:
Update Fix with colormaps. By utilising the colormaps tikz library you can set the desired color map and obtain what you desire. As in:
documentclass[tikz]{standalone}
usepackage{pgfplots}
usepgfplotslibrary{colormaps}
% Note that this is the colormap definition. You can play with this however you want. Fun fact: this color map also includes 8bit color code definition. Which can be defined using rgb255 = {value,value,value}.
pgfplotsset{colormap={CM}{rgb=(0,0,1) color=(red) rgb=(0,0,1)}}
begin{document}
begin{tikzpicture}
begin{axis}[point meta = y, colormap name={CM}]
addplot [mesh, variable=x, samples=100,domain=-10:10] ({x},{sin(deg(x))+0.6*x});
end{axis}
end{tikzpicture}
end{document}
which will give you:
Update Credits goes to @marmot.
You can an inline function in point meta definition to customise your colormap implicitly using an explicit function (see @marmot's comments).
documentclass[tikz]{standalone}
usepackage{pgfplots}

begin{axis}
[ colormap/hot] addplot [point meta = x*x*x,mesh, samples=100,domain=-10:10] {sin(deg(x))+0.6*x};
end{axis}
end{tikzpicture}
end{document}
Here, I used cubic function for manipulating the color map. This will give

Thanks, but I think this misses the bit that the color gradient should depict this a function, (in my question i used the example of x^2)
