Fill area under curve using colourmap and Tikz
1
I'd like to use a colourmap like hot2 in this plot, where red occurs at x=0, and green occurs at x=1, but I can't find any way of doing it.
Here's what I have so far:
begin{tikzpicture}
begin{axis}[
axis lines=left,
grid=major,
no marks,
xmin=0, xmax=1, xlabel=$E$,
ymin=0, ymax=1, ylabel=$lambda$, ylabel style={rotate=-90}
]
addplot+[smooth,blue,name path=A] {1 - (1 - x)^2}; % actual curve
addplot+[draw=none,name path=B] {0}; % “fictional” curve
addplot+[green] fill between[of=A and B,soft clip={domain=0:1}]; % filling
end{axis}
end{tikzpicture}

Welcome to TeX-SE! We usually begin our examples with documentclass, end them with end{document} and do not put non-standard characters in the code that prevents others from copying it. The following is an example of an MWE.
documentclass[tikz,border=3.14mm]{standalone}
usepackage{pgfplots}
pgfplotsset{compat=1.16}
newsaveboxbackbox
pgfplotscolormaptoshadingspec{hot}{7cm}result
deftempb{pgfdeclarehorizontalshading{tempshading}{7cm}}%
% where 'result' is inserted as last argument:
expandaftertempbexpandafter{result}%
sboxbackbox{pgfuseshading{tempshading}}%
begin{document}
begin{tikzpicture}
begin{axis}[set layers,view={90}{0},
axis lines=left,
grid=major,
no marks,
xmin=0, xmax=1, xlabel=$E$,
ymin=0, ymax=1, ylabel=$lambda$, ylabel style={rotate=-90}
]
addplot+[smooth,blue] {1 - (1 - x)^2}; % actual curve
begin{pgfonlayer}{pre main}
clip plot[variable=x,samples=25,domain=0:1] (x,{1 - (1 - x)^2})
|-cycle;
node at (0.5,0.5){useboxbackbox};
end{pgfonlayer}
% filling
end{axis}
end{tikzpicture}

@JordanMackie Sorry, these statements seem to contradict each other: "it works" and "I get an error". I get this very output from runningpdflatexon the above code, of course without error message.

It does produce the same output, but compilation always trips up on that error, so it's not a major

@JordanMackie An error is major, but I do not get one if I compile the above on an updated TeXLive 2018 distribution with pdflatex. Which TeX installation and compiler do you use?
