Matlab extends graph in EPS export beyond limits - matlab

I encountered strange behavior from Matlab when using the eps export. When I set up a figure like this:
subplot(2,1,1)
x = [duration([-3, 0, 0]), duration([-2, 0, 0]), duration([-1, 0, 0]), duration([0, 59, 59]), duration([1, 0, 0]), duration([2, 0, 0]), duration([3, 0, 0]), duration([3, 0, 1]), duration([5, 0, 0])];
y = [0, 0, 0, 0, 1, 1, 1, 0, 0];
plot(x,y)
set(gca,'XLim',[0 operationEnd-operationStart]);
xtickformat('hh:mm');
box off
subplot(2,1,2)
yyaxis left
plot(x,y)
yyaxis right
plot(x,y,'--');
set(gca,'XLim',[0 operationEnd-operationStart]);
xtickformat('hh:mm');
saveas(f,[PATH_SAVE,'eps_export_issue'],'eps2c');
The resulting figure looks in Matlab like this:
However when I open the exported EPS in Inkscape it seems to ignore the set XLim if the figure and it looks like this:
The issue also occurs if I don't use subplot and don't use duration as this snippet:
x = [-3, -2, -1, 0.99, 1, 2, 3, 3.01, 5];
y = [0, 0, 0, 0, 1, 1, 1, 0, 0];
f = figure();
yyaxis left
plot(x,y)
yyaxis right
plot(x,y,'--');
set(gca,'XLim',[0 4]);
box off
saveas(f,'eps_export_float','eps2c');
leads to an exported EPS that looks like this with the same issue:
How can I resolve this?

Moving a curve inside a figure

As you can see, in the first picture I have two subplots, two the same, with the same curve position. But I need to change the curve position/or view angle of one of the subplot (doesn't matter now if the left one or the right one). The only working command is CameraViewAngle but it changes for both of it, I don't know why, and I need to be able to change for each one seperately.
As you can see in picture two, the view angle changes for both of it. I would rather chagne only the curve position.
The code I'm using is:
function [pointsQRS, pointsP, pointsT] = VCG (pointsQRS,pointsP,pointsT)
global ax1 ax2 h
figure('Name','Vektorkardiogram','NumberTitle','off','Color',[0.8 0.8 0.8])

linkaxes([ax1, ax2])
I need it to change it in order to achieve 3D stereoscopic view using Google Cardboard.
Thank you in advance for any help!
PS: For example I want to achieve something as in the picture 3
But in the picture three the 3D curves are not connected, by connected I mean that while I move with one of them, the other one will be moved in the same way.

I managed to partially solve it.
Changing CameraViewAngle, modifies the size of the curve, so I decided to keep it unmodified.
Instead of setting the angle, set CameraPosition of ax2 to be different than ax1, but keeping the same distance from the target.
Instead of using linkprop, I used addlistener, and implemented a callback function that sets the CameraPosition of ax2 when CameraPosition of ax1 is modified.

plotting a curve in MATLAB with prefefined x-axis

I have two vectors:
x = [1, 2, 3, 5, 6, 10, 20, 50, 100]
and
y=[7, 1, 2, 4, 2, 1, 5, 1, 1];
I am interested to plot Y as a function of X in MATLAB. So, this can be done by:
figure;
plot(x, y, '--rs');
In fact, the code above plots the curve, but the x-axis seems to be spaced as follows: 0, 10, 20, ..., 100.
What I want is to draw a curve which exhibits just the values in x as x-axis and their corresponding y-axis values. An example of x-axis is shown in the picture below.
Any help will be very appreciated!!

Instead of plotting using plot(x,y), use plot(1:numel(x),y) and use the XTick and XTickLabels` properties to change the labelling of the graph to suit your need.
Example:
clc
clear
x = [1, 2, 3, 5, 6, 10, 20, 50, 100];
y=[7, 1, 2, 4, 2, 1, 5, 1, 1];
plot(1:numel(x),y,'--rs')
set(gca, 'XTick', 1:length(x)); %// Change x-axis ticks
set(gca, 'XTickLabel', x); %// Change x-axis ticks labels.
Result:
Hope that helps!

Hatched bars and standard deviation errors in bar charts with Matlab

I'm trying to create a bar plot. On the x axis I have 4 different conditions: HFd, HFi, LFd, LFi. On the y axis Reaction time is displayed.
I need the bar representing HFd to be hatched and blue, HFi to be blue, LFd to be hatched and red, LFi to be red. In addition, I need the standard deviation to be displayed in black on each bar.
Here are my attempts. Although they work, they don't give me the bar plot I need. Any help would be very much appreciated.

How do I plot a triangle in three dimensions? [duplicate]

This question already has answers here:
How can I plot a 3D-plane in Matlab?
(4 answers)
Closed 8 years ago.
I would like to draw different triangles by using MATLAB shown in the figure below. Suppose that I have 3 vectors V1=[1 1 1], V2=[-1 1 1], v3=[-2 -2 -2].
How can I draw triangle with these vectors in 3D?
![enter image description here][1]

You can use plot3() like this:
v1=[1 1 1]; v2=[-1 1 1]; v3=[-2 -2 -2];
triangle = [v1(:), v2(:), v3(:), v1(:)];
plot3(triangle(1, :), triangle(2, :), triangle(3, :))
xlabel('x'); ylabel('y'); zlabel('z');
This is the output:
Edit:
This is in order to plot axis:
val = 5; %// Max value of axis
axX = [0 0 0; val 0 0];
axY = [0 0 0; 0 val 0];
axZ = [0 0 0; 0 0 val];
plot3(axX(:, 1), axX(:, 2), axX(:, 3), 'k');
plot3(axY(:, 1), axY(:, 2), axY(:, 3), 'k');
plot3(axZ(:, 1), axZ(:, 2), axZ(:, 3), 'k');
text(val, 0, 0, 'x')
text(0, val, 0, 'y')
text(0, 0, val, 'z')
view(3)
In addition you can make the plot look like your reference image, adding these commands to above code:
set(gca,'xtick',[], 'xcolor', 'w')
set(gca,'ytick',[], 'ycolor', 'w', 'YDir','reverse')
set(gca,'ztick',[], 'zcolor', 'w')
view(45, 30)
This is the result:

How to display two overlapping lines in matlab

I have to plot 5 lines that overlap in some regions, and I need to be able to see all the lines.
I can think of shifting the lines a bit to allow them to be displayed, but this doesn't seem a very elegante solution. Even so, how could I code such a thing?
Is there any other way to plot multiple overlapping lines while being able to distinguish them at every point?
For exemple, here is one exemple with 3 overlapping lines:
Thank you in advance!

Another way is to use transparency.
Unfortunatelly, line objects do not obey
transparency commands :(
A workaround is to:
1. download patchline (<-- link to Matlab Central)
2. use it to plot patchline with transparency
Once you have patchline, you can try something like:
% create some lines:
l1 = [1, 1, 1, 0, 0, 0.25, 1, 1, 0, 0, 0, 0, 1 1];
l2 = [0, 1, 1, 1, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1];
l3 = [1, 1, 0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0, 0];
% plot with patchline (notice the use of 'EdgeAlpha'):
figure;
patchline(1:length(l1), l1, [], 'EdgeColor', [0.8, 0.2, 0.35],...
'LineWidth', 5, 'EdgeAlpha', 0.5 );
hold on;
patchline(1:length(l1), l2, 'EdgeColor', [0.2, 0.7, 0.55],...
'LineWidth', 5, 'EdgeAlpha', 0.5 );
patchline(1:length(l1), l3, 'EdgeColor', [0.1, 0.2, 0.95],...
'LineWidth', 5, 'EdgeAlpha', 0.5);
% change y limits to see line overlap clearly
set(gca, 'YLim', [-0.5, 1.5]);
Not an ideal way to do it - the rough 'cracks' will stay this way,
but you can experiment with different line widths or moving the
lines in y axis by a value that would correspond to an image with each
line covering only half of it closest neighbour...

You may play with EraseMode property of the plot line. The following code example shows how to shift the lines and EraseMode effect:
% First we generate some data
NLines = 2;
NPoints = 50;
LineWidth = 3;
ShiftStep = 1.1;
XData = linspace(0,1,NPoints);
YData = rand(NPoints,NLines);
for k=1:NLines
YData(:,k) = YData(:,k) > (k/(NLines+1));
end
% Then we create plot
figure('color','w');
subplot(3,1,1); plot(XData,YData, 'LineWidth',LineWidth);
ylim([-0.1 1.1]);
title('simple')
subplot(3,1,2); plot(XData,YData+repmat((0:NLines-1)*ShiftStep,NPoints,1), 'LineWidth',LineWidth, 'EraseMode','xor');
ylim([-0.1 1.1+ShiftStep*(NLines-1)]);
title('Shifted vertically')
subplot(3,1,3); plot(XData,YData, 'LineWidth',LineWidth, 'EraseMode','xor');
ylim([-0.1 1.1]);
title('EraseMode = xor')
In my opinion if you have more than three lines similar to your plot, shifting is visually more attractive. Also you may create several axes (Like I did) and plot each line in its own axes, so they will have y-labels set accordingly, but their X-labels will be essentially the same.

You can use plot3 and assign different Z values to different overlapping lines. However, it'll look more like you expect (Z being the "up" direction) if you swap the Y and Z axes:
Example:
Y1 = randn(1,100);
Y2 = randn(1,100);
X = 1:100;
Z1 = 1*ones(size(X));
Z2 = 2*ones(size(X));
plot3(X,Z1,Y1);
hold on;
plot3(X,Z2,Y2);
