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, PlotRange -> All, ColorFunction -> "TemperatureMap"], {ColorData["TemperatureMap"][#1] &, 10, ToString[Min[mydata]], ToString[Max[mydata]], LegendPosition -> {1.1, -0.8}, LegendSize -> 1.5, LegendShadow -> None}] ----- Original Message ----- From: "Bob Hanlon" <hanlonr(a)cox.net> To: "Eric Gonzalez" <cire.glez(a)gmail.com>; <mathgroup(a)smc.vnet.net> Sent: Tuesday, January 19, 2010 5:01 AM Subject: Re: Contour plot with color scale > > Needs["PlotLegends`"] > > ShowLegend[ > ContourPlot[ > Cos[x] + Cos[y], > {x, 0, 4 Pi}, {y, 0, 4 Pi}, > Contours -> 9], > {ColorData["LakeColors"][1 - #1] &, > 10, " 2", "-2", > LegendPosition -> {1.1, -0.4}}] > > > Bob Hanlon > > ---- Eric Gonzalez <cire.glez(a)gmail.com> wrote: > > ============= > Hello, > I want to make a contour plot witht the color scale with the appropiate > min > and max on the side,???? > bests, > Eric
