Overlay curves over heatmap

Hello everyone,
I was wondering if it is possible to plot curves over heatmap. It goes something like this:
X = 20:20:1000;
Y = 100:-2:1;
Z = randi(100,50,50);
h = heatmap(X,Y,Z);
hold on
for ii=1:5
curve = ii+1000./X;
plot(X, curve)
end
hold off
I want the curves to be above the heatmap. For example, in the figures below,
the right figure should be on top of the left figure.
Any ideas?
Thanks in advance!

How about the following way?
The following is an example.
% Sample data
cdata = [45 60 32; 43 54 76; 32 94 68; 23 95 58];
figure
heatmap(cdata)
colorbar
ax = axes;
plot(ax,magic(4),'LineWidth',2)
ax.Color = 'none';
% Maybe it needs some adjustment, like:
ax.Position(3) = 0.72;
ax.XTick = [];
ax.YTick = [];

How to apply this concept for subplot? when use ax = axes, it use the whole space, not the subplot space
