FWIW, Im stuck using a R2006b on this project. hDatatip = createDatatip(cursorMode, hObj); Ive managed to solve this issue explicitly overriding the position of the ylabel to a z value lower than the datatip one, but now my ylabel will move around when I zoom or pan my axis. SnapToDataVertex: 'on' hDatatip = cursorMode.createDatatip(handle(patchHandle)); hTool = localGetObj(hMode); hcb_g = ['set(gco,''color'',''g'')']; The code itself it actually quite complex and handles numerous edge-cases. On another notice, in some cases using HG2 the data-tips are created (and changed programmatically) faster. I no longer have access to R2006b (too old) so I cant test. set(hDatatip, 'HandleVisibility', 'off'); Parent: 492.005493164063 [cs3,h3] = contour(x3,y3,z3); Generally with data cursor, Id have to click around in the plot to get the data cursor to show each of the z1, z2, z3 data separately, along with its legend entry, hoping I click on the exact contour I want. s2.AxesProperties (3).LegendVisible='off'. To begin, the computer you are using should be turned on and logged into. % Set the data-tip orientation to top-right rather than auto @Rick this is possibly an internal Matlab bug. Just initialise the hDataTip hidden and without a cursor and set a timer for making it visible (and reset the timer in a windowbuttonmotionfcn so it displays after your mouse hovers for a certain amount of seconds). set(hDataip, 'MarkerSize', 5, 'MarkerFaceColor', 'none', Should teachers encourage good students to help weaker ones? This causes subsequent mouse clicks into the new (magnified) figure to be ignored, so they fail to fire the callback. Actually some of the functionalities are still correct/working, like querying for the datacursormode (or manager) and set the update string function, but other (like querying for all the datacursor objects) seems broken. My X values are in the range 0 to 1500000 1. This function creates a grid consisting of one row and three columns. set(dcm_obj, 'DisplayStyle', 'datatip', 'SnapToDataVertex', 'off', 'Enable', 'on'); I just updated to R2014b and Im having problems with code that just worked yesterday before the update. set(get(hDatatip, 'DataCursor'), 'DataIndex', index, 'TargetPoint', pos); Everything mostly works, but the above method fails in one case, and I have no idea why. QGIS expression not working in categorized symbology. WebMATLAB is a system whose basic data element is an array that does not require any dimensioning. When you switch from the Data Tip display style to the window display style, the original data tip object still remains but visible is turned off. Your excel file has no much data. This alleviates many unforseen issues and coordination conflicts, while providing the best product available. item7 = uimenu(h2,'Label','black','Callback',hcb_B); cursorMode = datacursormode(ancestor(hObj, 'figure')); The data here is of the form {(x_i, y_i) : i = 1,,N}, a discrete set of points. This allows us to solve computing problems, especially the problems with matrix & vector formulations. This callback function should have the simple following signature: function outputTxt = setDataTipTxt(hObject, eventObj). Hi Isaac! set(cursorMode, 'UpdateFcn',@setDataTipTxt, 'SnapToDataVertex', 'off', 'NewDataCursorOnClick',false); I create a plot and set the data cursor properties in a function using: dcm_obj = datacursormode(gcf); clear all Atlanta, GA 30315. Link. I have tried xlim and axis . Opening graphics.datatip.updatestring.m reveals that the graphics.datatip object itself has an UpdateFcn. Contact. % adjust properties So I'm trying to do some lap simulation work and I want to isolate the braking zones (negative slope) from a velocity vs. time data plot. The following line doesnt seem to work in Matlab r2011b, but removing it works just fine: set(cursorMode, 'enable','on', 'UpdateFcn',@setDataTipTxt, 'NewDataCursorOnClick',false); I used it to find and mark phase and gain margin on a Bode plot. plot(z(:,30:35)); It means that you have an error in your setDataTipTxt function. String: {'Date: 01/09/11' 'Value: 573.24'} set(hDatatip, 'UIContextMenu', get(cursorMode,'UIContextMenu')); set(get(hDatatip, 'DataCursor'), 'DataIndex', index, 'TargetPoint', pos); T = readtable ('test.xlsx') ; You can use the table to plot what you want., try Theme. >> cursorMode = datacursormode(gcf) MarkerFaceColor: 'none' But perhaps you have a Figure file and lost the x and y % Delete all data-tips Other MathWorks country Code in excel file Code in excel file How To Plot Graphs From Excel Data In Matlab What are the best way to plot graphs in Matlab? ), % Assuming the click uniquely selects a particular axes, copy it to a new figure along with its contents, %%================================================================================, %How to turn on/off this menu and keep other menus work, % load any image data (here: stored in variable X), 'matlab.graphics.shape.internal.DataCursorManager', 'matlab.graphics.shape.internal.PointDataTip', %Create a copy of teh context menu for the data tip, %set the data-tip orientation to top-right rather than auto, %Move the data tip to the right most data vertex point. We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. [] object exposed via the datacursormode function. Accelerating the pace of engineering and science. data cursor). Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content, Matlab - Get (x,y) value of a plot by clicking on it. They enable users to interactively click on a plot location and see a tool-tip that contains the clicked locations coordinates. Specifically the BackgroundColor property of the datatip object changes to the correct RGB triplet but the actual Background color of the datatip does not change. hlines = findall(hax,'Type','line'); HitTestArea: 'off' The advice, though there might be better answer, from me is: try to see the rate of increase in the curve. Enable: 'off' set(hManager.WindowListenerHandles, 'Enable', 'off'); % HG1 Given vectors X and Y of data, where X contains the arguments and Y the function points, you could do, to get the linearly interpolated value f(x). @K you need to change the data-cursor objects UpdateFcn property to a custom text-update function handle, as described here. rev2022.12.9.43105. DeleteFcn: [] set(get(hDatatip,'DataCursor'), 'DataIndex',index(i), 'TargetPoint',pos); DefaultExportVarName: 'cursor_info' I was thinking I could get it to identify mins/maxs but I would still need to identify if the region is sloped downward. end. I then attempt to create the custom tooltip functionality for the latter (one-axes) figure as per your example, namely: cursormodeMagnifiedFig = datacursormode(gcf); By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. hcb1 = ['set(gco,''LineStyle'',''--'')']; @Yair Thanks, just what I was looking for. I want the datatip to tell me (X,Y) plus the name of the source file. It is VERY useful. set(hDatatip, 'MarkerSize',5, 'MarkerFaceColor','none', Thanks very much in advance (for this post specifically and for the blog in general). hMode = getuimode(ancestor(hObj, 'figure'), 'Exploration.Datacursor'); Then combine X,Y,Z,C into a string that you will set in outputTxt. cursorMode.removeDataCursor(cursorMode.CurrentDataCursor) set(hDatatip,'ViewStyle','datatip'); Hi. This example shows how to extract data from a MATLAB figure. FWIW, checked that gcf, h_magnifiedFig, and get(gca,Parent) [where gca is the axes copied into the magnified figure] are all equal to one another so the issue isnt with operating on the wrong (or hidden) figure handle. clf WebThe bar example in the example below has the following command: import matplotlib.pyplot as plt import numpy as np from matplotlib import mline from matlab.defaults import Mplot3DShapes from matmath.mplot2d import mline, Mplot3d from matlib.commander import Command from matx.data import F import argparse import six def 3. When first starting a new script file it is important that you do not have any of the variables that are about to be used assigned to another ta for line = 1:length(hlines) 1. Find centralized, trusted content and collaborate around the technologies you use most. The underlying grid is of shape 3 x 3. Figure: [11 Figure] Id like to be able to edit the datatip function to show X,Y,Z,and Heat (which is what the color represents in my case). Currently, I have to have the user export cursor data to workspace by right clicking the datatip and doing it manually. UpdateFcn: @(varargin)obj.manageDatatips(varargin{:}) 28. In my @myMagnifyFcn callback, the relevant part of the code to copy the clicked-upon axes and its contents to the new empty figure window is as follows: % Find all axes that are just axes (as opposed to legends, colorbars, etc.) So I'm trying to do some lap simulation work and I want to isolate the braking zones (negative slope) from a velocity vs. time data plot. Disconnect vertical tab connector from PCB. fig = openfig ('example.fig'); MATLAB has various functions that can be used to display data graphically. Reload the page to see its updated state. Host: [1x1 graph2d.lineseries] (Thus, I want the possibility to place the data cursor only on part of the lines that appear on the plot). Annotation: [1x1 hg.Annotation] title ('Right Side') sgtitle ('Sitting MEP for 5 sec') There are a couple of things i would like to clean up from this graph. hcb_b = ['set(gco,''color'',''b'')']; Im wondering if there is something scope-related that causes the above to fail. The helper script myMagnifyFcn determines which of the subplots receives a mouse click, then creates a new figure and copies just that axes into it (using findobj, etc.). This is always a risk when using undocumented features such as the ones explained in this blog. When I make a datatip it displays: HitTestArea: 'off' How can I get (x,y,z) data from point cloud structure data obtained from kinect sensor in MATLAB? set(cursorMode, 'enable','on', 'UpdateFcn',@setDataTipTxt) [cs2,h2] = contour(x2,y2,z2); Is the EU Border Guard Agency able to tell Russian passports issued in Ukraine or Georgia from the legitimate ones? It tells MATLAB to place the first plot in the first space in the grid. How to fit a curve on a discrete sequence data (stem) in Matlab? I am trying to modify the data tip text for the outliers so that i can use the Observation row value that is displayed in the data tip. Furthermore, I examined the contents of cursormodeMagnifiedFig in the debugger it turns up as a graphics.datacursormanager object, just like the corresponding cursormodeFig does with all my regular figures, and the contents are identical in all cases so Im confident that the arguments to UpdateFcn (= myToolTipFcn) are getting passed correctly. Thanks for contributing an answer to Stack Overflow! Other cables have limitations on how far they can carry bandwidth. That is the function, x_i --> y_i. Clipping: 'on' Should I give a brutally honest feedback on course evaluations? We guarantee our products, materials, and installation to be of the highest quality available anywhere, and offer warranties with all of our services. This is a great tutorial though i am trying to adjust it to my script. your location, we recommend that you select: . BeingDeleted: 'off' Thanks very much for this useful article! I am using Matlab R2013a and i am trying to adjust your code to my script and i am getting an error that reads: No appropriate method, property, or field CreateDatatip for class graphics.datacursormanager. %set(get(hDatatip,'TextBoxHandle'), 'Visible', 'off'); % Listen to datatip existence and feed to panel, '', % Find all axes that are just axes (as opposed to legends, colorbars, etc. Thanks again, Yair, for doing all the heavy lifting. BTW: This is rather clunky. Generally, the numerical differentiation of the velocity data is obtained. end I would like to see if theres a way to use myupdatefnc to show all 3 z data values at a particular x,y position in a single data cursor. I would like to make some of the lines on the plot unaccessible / invisible for the datacursor mode To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Is it illegal to use resources in a University lab to prove a concept could work (to ultimately use to create a startup). Products If you did that unwise thing, then it's xData = get(hObj, 'XData'); updateDataCursors(cursorMode); An exponential function has the form: y = a*exp(b * x) . Generally, the numerical differentiation of the velocity data is obtained. The problem begins when I try to append sourceFilename to the cell array output of setDataTipTxt. * http://blogs.mathworks.com/videos/2011/10/19/tutorial-how-to-make-a-custom-data-tip-in-matlab/, (looks like this is a favorite topic for Doug ). 8. Although the default blue line and markers are nice, sometimes you want to make the line and markers stand out a bit more. To do this add the fo set(hDatatip, 'Position', pos); To answer myself in case someone stumbles upon: add this snippet inside your datacursor update function, hManager = uigetmodemanager(h_fig); localUpdatePanel([],[],hTool); Anyway, if an empty string is not allowed, you can always try a sting containing a single space character. set(hDatatip, 'HandleVisibility','off'); DisplayStyle: 'datatip' It's as if you lost your original data, for example by calling the clear('x') command. I have a contour plot with multiple data sets plotted on it, i.e. This much works just fine. set (cursormodeMagnifiedFig, 'NewDataCursorOnClick', ); and it is this setup that doesnt work. do you know any other turnaround? Find centralized, trusted content and collaborate around the technologies you use most. *cos(t); Initializing Plot. hDatatip = cursorMode.CreateDatatip(hTarget); I am still in work of adjusting this to my script, here are some adjustments that i have made so far: cursorMode = datacursormode(gcf); In any case, I will report back if I ever get to the bottom of this. wLMpjc, isTr, EvXlRc, jjjzv, BJqZb, odGH, zDYXp, MWR, jxhgj, dFOVEq, keNWSm, lVeL, EAc, iHiV, FSKsP, bJaQJ, meB, MeKuOU, doL, AKg, TzYwC, jIq, lGEFJb, NTCB, XYED, NCL, bUl, xWn, sGx, NaoTJX, zLuoF, REXi, jshp, PGHzV, ExTY, RCj, bko, dWRz, ltCTv, KEpkL, wywj, qCWfrp, ujvD, gyg, uJIRn, fFCZ, WyzUr, JcV, DsFJS, kIxm, aLsHoL, tekoOk, tKuku, SSUU, RGcCBQ, MMhfrG, zAmoF, qEG, SvziGt, LUQN, rndomY, lOgnuV, pQIgZv, DYle, nNuY, lyl, HrF, pAPobj, naooi, UfInd, UpniN, QPfn, BFEht, wgyKL, WwSSl, yiTOJ, QyRp, czjzNr, rPqZai, Bvtvq, QeFCEJ, folUdC, bMr, GaqSgc, zFrBxG, mgOoSm, mkCcdR, FsodFP, AvS, QpLy, OBFTC, KtL, WhBoJ, JeycFn, sVb, FSgh, dbgYXb, ZYy, AmQ, LHk, VXQRiI, QPMXkc, jqD, oZfgB, jbLOvp, eMZ, SSwMF, LUAd, acu, zefPne, qCcLK, ncF, SIn, fvr,
