Sorry, I also meet some problem(revision R2018b) Attention reader! The help suggests using AXIS(AXIS) to fix the limits, I think the same effect can be acheived with AXIS MANUAL, which would be clearer. plot(x,y) varargin(3) = []; plot([startpoint(1) endpoint(1)],[startpoint(2) endpoint(2)],'linewidth',2,'color',[0 0 0]); Useful in many ways but the code is very complicated and it's not clear how to attain specific effects without trawling through the function body. x = rad*(omega*t -sin(omega*t)); 5 stars for the function. Awesome application! Did you manage to resolve the problem? I have a function which control an external board I have controlling a motor. xlabel('x label'). close all; clc; function arrow2(varargin) ARROW (5/25/2016) Draw a line with an arrowhead.

Sorry, but does not work for me (revision R2108a): arrow_gap = arrow_gap_pc*r; Thanks. 4. I have another set of related changes. You can change the color of each arrow (SetQuiverColor) and change the length of each arrow (SetQuiverLength) in units of … Exactly what I was looking for. hh=arrow_demo3(demo_info); It seems that the ARROW cannot work with Matlab R2015a version. Can you elaborate? Does not display arrow if arrow falls outside of axes boundaries. H(k) = patch(xyz{:},'HandleVisibility', 'off'); Jocelino, you probably want to set you xlimits and ylimits before calling arrow, e.g. mask = arrow_is2DXY(ax(oldaxlims(:,1))); >> arrow Any help would be greatly appreciated. Editor's Note: This file was selected as MATLAB Central Pick of the Week Popular File 2012 2013. I tried to include 'CrossDir',[0 0 1] as suggested by the author of the script, but it didn't help. Follow 31 views (last 30 days) Andrew on 9 Jun 2015. arrow([0;0;0],[0;1;0]) Works nicely, but i did find a bug: so please, Mathworks do a arrow / arrow3 function!!! In the legend, the four arrows show up with the labels "data1", "data2", "data3", "data4". Find the treasures in MATLAB Central and discover how the community can help you! set(gcf,'position',[100,250,750,600]). so as not to obscure a marker), I've written a slight update (note: not compatible with arrow.m properties directly, but you could easily adapt): function [varargout] = my_arrow(start,stop) I was trying to make a arrow in a gui window. arrow([0;0;0],[1;0;0]) "You may want to execute AXIS(AXIS) before calling arrow so it doesn't change the axes on you; arrow determines the sizes of arrow components BEFORE the arrow is plotted, so if arrow changes axis limits, arrows may be malformed.". >arrow([0;0;0],[0;0;1]) x2 = x1 + v2; Yes, I was using an old version of arrow.m function (5/20/09). Follow 32 views (last 30 days) Andrew on 9 Jun 2015. H(k) = patch(xyz{:}); You are brilliant. clf Using arrow with this script yields an unusually long arrow in the z direction, which is quite annoying. , and ':'? There are various properties of Quiver Plot in Matlab which are discussed below: Arrow color can be modified by ‘Color’ property with the respective values. Can you email me some code? The default value of [0 0 0] corresponds to black. In MATLAB, a string is a character array. The code: If I avoid debugging then the problem disappears. ", figure; In MATLAB, comments are of two types: Single-line Comments; Block Comments; Spanning MUltiple Lines; Single-Line Comments. Admittedly I was drawing thousands of arrows at extremely short lengths. It's also not obvious that the arrow will be a patch object, so has properties like edgecolor, facecolor, rather than line properties. As an alternative, there is now the DaVinci Draw toolbox, davinci-draw.com, which uses low-level Matlab commands like plot() and patch() to draw mid-level shapes like arrows. 2 Comments Show Hide all comments ah = arrow(b,e); Double arrow, with line for shaft. (And "global test" to the top of the arrow function) Arrowline 3-D vector plot. thanks a lot. Hello Matlab community, I am trying to draw an arrow. Very helpful and thorough! if isempty(oldh), H=gobjects(narrows,1); else, H=oldh; end; >> set(h,{'FaceColor' 'EdgeColor'},repmat({'r';'g';'b';'m';'k'},1,2)).

For example, the position can not be adjust by mouse. Example. Thanks! The computed values of mean and stdev appear in the Display blocks. I hate how MATLAB uses normalized figure coordinates in their annotation() call for drawing arrows. (Email address is in the m-file; or click on my name then "view profile" then "Contact". Generate arrow keys in MATLAB gui. I edited the function to add message identifiers so I could turn them off - don't need my Command Window cluttered up with a lot of orange text. 'EdgeColor', 'k', ... ARROW3(P1,P2) draws lines from P1 to P2 with directional arrowheads. >> x=(0.1:.2:.9)'; h=arrow([x .1+x*0],[x .9+x*0]); ), Dear Erik, I am running several Matlab versions (2016a, 2016b and 2017a) and the "strange behavior" is that the arrows are distorted in both, length and shape of the arrow head. But nonetheless it would be nice if they would be perfect by default ;-), This code, at least on R2009a, looks very strange. Couldn't figure out how to make the arrow line and arrow head have a specific color. if nargout == 1 arrow([max(X) max(Y) Z1],[min(X) min(Y) Z1],15,'BaseAngle',60, 'FaceColor',[0 1 0]). % vectarrow(p0,p1) plots a line vector with arrow pointing from point p0 % to point p1. This is great, I messed around with the annotations for 1.5 hours before finding this. figure Now the arrows change the size of the subplot so that the subplots are no longer of equal size. Ooops, my bad. I modified your code slightly... instead of doing my own image sampling, I used the imresize command from the image tool box. setting the view before the arrow functions solves your problem e.g. ------------NEW------------ Thanks. % arrow is plotted, so if ARROW changes axis limits, arrows may be malformed. Terrific. Other MathWorks country sites are not optimized for visits from your location. Generate arrow keys in MATLAB gui.

Previous: Line 423 ax = o * gca; (code) Read Analog from Arduino into Matlab. Is there a way to fix this? Excellent package. I'm using arrow.m to draw arrows which represent data on the plot and it would be helpful to have a blue arrow in the legend. ------------ORIGINAL------------ and see. Superb effort. Don’t stop learning now. Vote. arrow keys input keyboard keypressfcn. global test How to change the line type? Can you give a minimal working example to demonstrate it? >> arrow DEMO One can change the colour of an arrow by specifying 'FaceColor' and 'EdgeColor' properties, which is, unfortunately, not documented. Many thanks. The following Matlab project contains the source code and Matlab examples used for arrow3 version 5. A shame by the way Matlab doesn't seem to have a builtin function for drawing arrows from the command line.
