[BUG] LaTeX error in PGFPlotsX backend.

[zhiyuanzhai]

Details

For some data sets, there is a possibility when PGF cannot recognise some of the "operators". For example:

pgfplotsx()

x = y = LinRange(1e-8,1e-5,100);
A = x .+ y';
contour(A)

gives the following error:

! Package PGF Math Error: Unknown operator `×' or `×1' (in '5.00×10⁻⁶').


See the PGF Math package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.1912 \end{axis}

Backends

This bug occurs on ( insert x below )

Backend	yes	no	untested
gr (default)		x
pyplot		x
plotlyjs		x
pgfplotsx	x
unicodeplots		x
inspectdr		x
gaston		x

(Haven't test this in other backends, but I'm definitely sure that this is PGF-only since it's a LaTeX error.)
