I try to superpose points with plot on pcolor and I only get the plot or the pcolor which is the furthest in the code lines.

I try to switch orders but I can't find the right way to get the points of plot and the pcolor on the same figure.

Refer to figure matlab_fig1.fig for the plot command and to matlab_fig2.fig for the pcolor command.

Here is my code:

        figure(1)
        hold on;
        colormap(jet);
        clf;
        plot(xdomain,ydomain,'r+');      % refer to --> matlab_fig1.fig     DOES NOT APPEAR
        pcolor(diff);                    % refer to --> matlab_fig2.fig     I ONLY GET THIS LINE
        colorbar;
        caxis([-1, 1]);
        colorbar('Ticks',[-1,0,1]);
        shading flat;
        figure(gcf);

Thank you

在 MATLAB Online 中打开

You call clf() after changing hold status to 'on'

this clears your figure, therefore resets your hold status to 'off'.

move clf() before your hold on; statement:

figure(1)
clf;
hold on;
colormap(jet);
plot(xdomain,ydomain,'r+');      % refer to --> matlab_fig1.fig     DOES NOT APPEAR
pcolor(diff);                    % refer to --> matlab_fig2.fig     I ONLY GET THIS LINE
colorbar;
caxis([-1, 1]);
colorbar('Ticks',[-1,0,1]);
shading flat;
figure(gcf);
