pcolor and contour plot with different colormaps

contour with gray colormap using external tools

Besides the solution presented above it is possible to use the tools freezeColors and COLORMAP and COLORBAR utilities to change the colormap in a single figure.

% clear command window, figures and all variables
clc; clf; clear all; 
 
%% Common variables
 
FontSize = 12;
FontName = 'MyriadPro-Regular'; % or choose any other font
 
doExportPlot = true;
 
%% Plot variables
SaveDir = '';
 
TITLE = '';
    xLabelText = 'x-values';
    yLabelText = 'y-values';
    zLabelText = 'function values';
 
 
%%
SaveDir = '';
BaseDir = '';
%% Create Data
[x y data] = peaks(1000);
data = data - min(min(<span class="hiddenGrammarError" pre="">data));
data</span> = data / max(max(data));
 
%% start plot
 
% figure dimensions in cm. I choose 1.5 or 2 times 
% the target size typically. If figure is display in
% document much smaller increase the fontsize.
 
figure_width = 14;  
figure_height = 10;
 
% --- setup plot windows
figuresVisible = 'on'; % 'off' for non displayed plots (will still be exported)
hfig = figure(1); clf;
    set(hfig,'Visible', figuresVisible)
 
    set(hfig, 'units', 'centimeters', 'pos', [5 5 figure_width figure_height])   
    set(hfig, 'PaperPositionMode', 'auto');    
    set(hfig, 'Renderer','zbuffer'); 
    set(hfig, 'Color', [1 1 1]); % Sets figure background
    set(gca, 'Color', [1 1 1]); % Sets axes background
 
% --- dimensions and position of plot 
hsp = subplot(1,1,1, 'Parent', hfig);
set(hsp,'Position',[0.12 0.15 0.80 0.8]);
 
colorDepth = 1000;
