Make a 2D plot with one arbitrary axis
显示 更早的评论
I’d like to make a 2D plot like the attached file in MATLAB. My problems are: 1. As the vertical axis is arbitrary, how can I plot a 1D- vector in MATLAB with x, y? I mean we have just data for x-axis (VEC) and how we can plot this vector in a 2D plot while the y-axis is arbitrary? VEC=[2 6 4.5 5 3 6.2 8 2.4]; 2. How can I add those dashed vertical line in a 2D plot? 3. How can fill the inside of the plot with colors? I mean left hand side of the dashed vertical line with a yellow (for example)? Is that possible to make different filling color for each section between the vertical dashed lines? (just like the attached file)
Best, Majid

You can start with something like this
bpoints = [6.88, 7.84];
color = summer(numel(bpoints) + 1); % or whatever colors you like
v = [5 6.2 8, 9];
h = plot(v, v, 'LineStyle', 'none');
h.Parent.Box = 'on';
ylim = h.Parent.YLim;
xlim = h.Parent.XLim;
h.Parent.YTickLabel = [];
bpoints(end + 1) = xlim(2);
offset = xlim(1);
for i = 1:numel(bpoints)
xx = [offset, bpoints(i), bpoints(i), offset];
yy = [ylim(1), ylim(1), ylim(2), ylim(2)];
patch(h.Parent, 'XData', xx, 'YData', yy, 'FaceColor', color(i, :), ...
'EdgeColor', 'none', 'FaceAlpha', 0.5)
offset = bpoints(i);
if i < numel(bpoints)
xline(h.Parent, bpoints(i), '--', 'LineWidth', 1.4)
end
end
xlabel('VEC')
h.Parent.FontSize = 12;
h.Parent.FontWeight = 'bold';
And then you can add text objects wherever you need (for dots/squares you can also use scatter or plot)

Not sure about it. What happens if you try without axes handle?
patch('XData', xx, 'YData', yy, 'FaceColor', color(i, :), ...
'EdgeColor', 'none', 'FaceAlpha', 0.5)
Or even only with xx and yy?
patch('XData', xx, 'YData', yy)

fill command will be suitable define your 3 squares as vectors , for y make it equal 1 for your graph I think
x1=[6.4 6.88 6.88 6.4 6.4];
y=[0 0 1 1 0];
x2=[6.88 7.84 7.84 6.88 6.88];
x3=[7.84 9 9 7.84 7.84];
d1=[6.88 6.88];
d2=[7.84 7.84];
figure(1)
fill(x1,y,'g')
hold on
fill(x2,y,'r')
fill(x3,y,'g')
plot(d1,[0,1],'b:')
plot(d2,[0,1],'b:')
