Hi everyone,
I have a problem with adding secondary Xaxis to my plot. I use MATLAB 2017b.
Here is my CODE:
X=[300 400 500 600];
X2=[4 3.5 3.0 2.5];
Y=[0.3 0.4 0.5 0.6];
figure()
plot(X,Y);
ax=gca;
ax.XAxisLocation='top';
Now how to add X2 to the bottom ?
Please help me.

Here is one possible solution:
X1=[300 400 500 600];
X2=[4 3.5 3.0 2.5];
Y=[0.3 0.4 0.5 0.6];
t = tiledlayout(1,1);
ax1 = axes(t);
plot(ax1,X1,Y,'-r')
ax1.XColor = 'r';
ax1.YColor = 'r';
ax2 = axes(t);
plot(ax2,X2,Y,'ko--')
ax2.XAxisLocation = 'top';
ax2.Color = 'none';
In case, you have two different sets of Y values, then
X1=[300 400 500 600];
X2=[4 3.5 3.0 2.5];
Y1=[0.3 0.4 0.5 0.6];
Y2=10*[0.3 0.4 0.5 0.6]
figure()
TT = tiledlayout(1,1);
ax1 = axes(TT);
plot(ax1,X1,Y1,'-r')
ax1.XColor = 'r';
ax1.YColor = 'r';
ax2 = axes(TT);
plot(ax2,X2,Y2,'ko--')
ax2.XAxisLocation = 'top';
ax2.YAxisLocation = 'right';
ax2.Color = 'none';
ax1.Box = 'off';
ax2.Box = 'off';

It should also work with this syntax
X1=[300 400 500 600];
X2=[4 3.5 3.0 2.5];
Y=[0.3 0.4 0.5 0.6];
t = figure(1);
ax1 = axes(t);
plot(ax1,X1,Y,'-r')
ax1.XColor = 'r';
ax1.YColor = 'r';
ax2 = axes(t);
plot(ax2,X2,Y,'ko--')
ax2.XAxisLocation = 'top';
ax2.Color = 'none';

%Random data
x1 = 0:0.1:40;
y1 = 4.*cos(x1)./(x1+2);
x2 = 1:0.2:20;
y2 = x2.^2./x2.^3;
%Define an axes and plot on it
ax1 = axes;
plot(ax1, x1, y1, '-r')
%Get the position of the axes
pos = ax1.Position;
%Define another axes on top of the previous one
ax2 = axes('Position', pos, 'XAxisLocation', 'top', 'Color', 'none');
%plot on it
hold(ax2, 'on')
plot(ax2, x2,y2,'-k')
%synchronize the y-axis
linkaxes([ax1 ax2], 'y')

Yes, one approach is to use white color for the curves -
%Random data
x1 = 0:0.1:40;
y1 = 4.*cos(x1)./(x1+2);
x2 = 1:0.2:20;
y2 = x2.^2./x2.^3;
%Define an axes and plot on it
ax1 = axes;
plot(ax1, x1, y1, '-w')
%Get the position of the axes
pos = ax1.Position;
%Define another axes on top of the previous one
ax2 = axes('Position', pos, 'XAxisLocation', 'top', 'Color', 'none');
%plot on it
hold(ax2, 'on')
plot(ax2, x2,y2,'-w')
%synchronize the y-axis
linkaxes([ax1 ax2], 'y')
