I don't have an IMTEK package. Try reversing the labels in the legend
specification. The legend is then "upside down"; however, it is
correct.

Needs["PlotLegends`"]

xyDat = Table[Sin[i + j^2], {i, 0, 3, 0.1}, {j, 0, 3, 0.1}];

ShowLegend[
 ListContourPlot[xyDat], {ColorData["LakeColors"][1 - #] &, 10, "1", "-1",
  LegendPosition -> {1.1, -.4}}]

ShowLegend[
 ListContourPlot[xyDat], {ColorData["LakeColors"][#] &, 10, "-1", "1",
  LegendPosition -> {1.1, -.4}}]

Alternatively, build your own legend from primitives.
