I'm trying to illustrate a confusion matrix, and when I scale every node and it seems to mess up the colorbar. Notice that the colorbar is not completely filled in.

And here's an MWE:

documentclass{standalone}



usepackage{pgfplots}

pgfplotsset{compat=1.13}



pgfkeys{

    /pgf/number format/fixed zerofill=true }



pgfplotstableset{

    color cells/.code={%

        pgfqkeys{/color cells}{#1}%

        pgfkeysalso{%

            postproc cell content/.code={%

                %

                begingroup

                 pgfkeysgetvalue{/pgfplots/table/@preprocessed cell content}value

ifxvalueempty

endgroup

else

                pgfmathfloatparsenumber{value}%

                pgfmathfloattofixed{pgfmathresult}%

                letvalue=pgfmathresult

                pgfplotscolormapaccess

                    [pgfkeysvalueof{/color cells/min}:pgfkeysvalueof{/color cells/max}]%

                    {value}%

                    {pgfkeysvalueof{/pgfplots/colormap name}}%

                pgfkeysgetvalue{/pgfplots/table/@cell content}typesetvalue

                pgfkeysgetvalue{/color cells/textcolor}textcolorvalue

                toks0=expandafter{typesetvalue}%

                xdeftemp{%

                    noexpandpgfkeysalso{%

                        @cell content={%

                            noexpandcellcolor[rgb]{pgfmathresult}%

                            noexpanddefinecolor{mapped color}{rgb}{pgfmathresult}%

                            ifxtextcolorvalueempty

                            else

                                noexpandcolor{textcolorvalue}%

                            fi

                            thetoks0 %

                        }%

                    }%

                }%

                endgroup

                temp

fi

            }%

        }%

    }

}
