I can't use scaled coordinates with BarChart:
Placed::labpos: "!(\"Inside\") is not a valid position for the placement of labels.
Module[{labels = {"HSTM", "SCOPUS", "ISI", "PubMed"},
data = {0, 13, 39, 25}},
BarChart[data, ChartLegends -> Placed[labels, {0.9,0.8}],
ChartStyle -> {RGBColor[0, 0, 0], RGBColor[0.8, 0, 0.2],
RGBColor[0.3, 0.8, 0.2], RGBColor[0, 0.3, 0.7]},
PlotRange -> {{0.5, 4.5}, {0, 40}}, Ticks -> {None, None},
AspectRatio -> 1.5, Frame -> {{True, True}, {True, True}},
FrameLabel -> {Style["", FontSize -> 18],
Style["nº de publicaciones", FontSize -> 18]},
FrameTicks -> {{{0, 10, 20, 30, 40}, None}, {None, None}}]]
Does anybody know how can I fix this?
