Thank you Bob,
I still have some problems. I am doing a MatrixPlot with values bewteen 0.6
to 180.0 ( ColorFunction ->
"TemperatureMap"], {ColorData["TemperatureMap"][#1] &, 10,
ToString[Min[mydata]], ToString[Max[mydata]], ) the 0.6 points does not
show blue in the plot so I dont think there is a correspodence between the
legend color map and and the chart. Also how to set several points in the
legend rather than the max and min?
thnk you for your help,
Eric
ShowLegend[
MatrixPlot[mydata, AspectRatio -> 1, Mesh -> All,

ToString[Min[mydata]], ToString[Max[mydata]],
LegendPosition -> {1.1, -0.8}, LegendSize -> 1.5,
LegendShadow -> None}]
