Hi Folks, I've got a 2D contour plot (x,y,z) and I want to overlay a line plot (x,y). The two graphs share the same x values. The hold on functions don't seem to help much. Any pointers?
fig1 = figure(1);
hFig = contour(gEmiFreq,gAbsFreq,MAmpl,c0.*SFac,...
'LineStyle','-','LineWidth',CntlineW);
line(DiagnlLine(1,:), DiagnlLine(2,:), 'LineStyle', '-', 'Color', [0 0 0],'LineWidth',LineW+.5);
axis(AxisDim);
caxis([0 1]);
set(gca,'xtickMode', 'manual', 'ytickMode', 'manual','LineWidth',2);
axis square; colormap jet;% colorbar;
hold on
plot(gEmiFreq(1,:),NormRef);
Normref is a 1x1024 laser spectrum and MAmpl,gEmiFreq, and gAbsFreq are 76x1024 arrays

I don’t know what the problem is, since what you describe should work. You didn’t post your code, so I can’t respond with a specific solution.
See 2D Filled Colour Plot for my previous (Accepted!) solution to a similar problem.

working test code:
clear all
NRow = 5; NCol = 5;
c0 = (0:.02:1);
MDim(1:4) = [[1475.40680000000,1511.70650000000,-1510.92820000000,-1475.06230000000;]];
[gEmiFreq, gAbsFreq] = meshgrid( linspace( MDim(1), MDim(2), NCol),...
linspace( MDim(3), MDim(4), NRow) );
MAmpl0 = abs(peaks(5));
MAmpl = MAmpl0/max(max(MAmpl0))
laser = [0 .5 1 .5 0];
fig1 = figure(1);
hold on
hFig = contour(gEmiFreq,gAbsFreq,MAmpl,c0);
caxis([0 1]);
set(gca,'xtickMode', 'manual', 'ytickMode', 'manual','LineWidth',2);
axis square; colormap jet;% colorbar;
plot(gEmiFreq(1,:),laser);

You probably won’t be able to overlay it on the contour plot, unless you use something like plotyy. The reason is that the y values are so different. Experiment with that to see if it solves your problem.
