By chance, do you know any event listener that is linked to the axis label, or to movement on the axis, so that I can solve this issue without seeing my axis label flying around my figure until mouse is released? How do I arrange multiple quotations (each with multiple lines) vertically (with a line through the center) so that they're side-by-side? addlistener(hDatatip,h); Ive tried several ways but always get the same message: Error in custom datatip string function. Other MathWorks country function CursorMode_Off_test Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. hLine = plot(xdata, ydata); 2. I think Ive found a solution. I then attempt to create the custom tooltip functionality for the latter (one-axes) figure as per your example, namely: cursormodeMagnifiedFig = datacursormode(gcf); Understanding it by simply reading the code (under %matlabroot%\toolbox\matlab\graphics\) is actually pretty difficult. @S_H just be to be clear, you actually have the numerical data that generated that plot? % Move the datatip to the right-most data vertex point But, most importantly, we stand by our work! my_figpanel = findall(gcf,'Tag','figpanel:text field'); https://au.mathworks.com/matlabcentral/answers/1869167-how-to-identify-negative-slope-from-plot-data, https://au.mathworks.com/matlabcentral/answers/1869167-how-to-identify-negative-slope-from-plot-data#answer_1118122, https://au.mathworks.com/matlabcentral/answers/1869167-how-to-identify-negative-slope-from-plot-data#answer_1118167. Using MATLAB 2018b, I have been able to change the EdgeColor and TextColor of the datatip, but the BackgroundColor will not update properly. The Matlab documentation says, You place data tips only by clicking data objects on graphs. In your case, y is the width of mixing zone, and x is the time in years. Thanks! pos = [x(index(i)) y(index(i))]; 'SnapToDataVertex','on', 'Enable','on', hDataTip.BackgroundAlpha = 0.65; Hi, Im working with MATLAB R2019a update 4 (the latest one I think), and I would like to know if there are some updates on how these features work. I would like to remove the plot labels from Y axis and instead just place a P, IC, RA and O where the left labels are. Text function writes everytime as I zoom in. The problem begins when I try to append sourceFilename to the cell array output of setDataTipTxt. pos = [xData(index) yData(index)]; @K you need to change the data-cursor objects UpdateFcn property to a custom text-update function handle, as described here. However, the "data cursor" tool in matlab just doesn't give the point I want. plot(z(:,30:35)); Based on This seems to be what the poster was referring to: @richard: I have data which I have plotted and shown in the question. Lets look at another example. You cannot expect them to remain unchanged forever. MarkerEraseMode: 'normal' updateDataCursors(cursorMode); [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. DefaultExportVarName: 'cursor_info' Do non-Segwit nodes reject Segwit transactions with invalid signature? load clown % load any image data (here: stored in variable X) Marker: 'o' Do you know anything about the underlying relationship? graphics.datacursormanager: As can be seen, if we really want, we can always use the MarkerHandle or TextBoxHandle directly. set(hDatatip, 'Position', pos); % set(hDatatip, 'ViewStyle','datatip'); MathWorks est le leader mondial des logiciels de calcul mathmatique pour les ingnieurs et les scientifiques. DataCursorManager with properties: 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 Ive tried this function based on your code and it works except I get tooltips instead of data in the window: function hDatatip = CustomDataTip(hObj, index, callbackhand) How is the merkle root verified if the mempools may be different? ['Y: ',num2str(pos(2))]}; s = surf(zeros(size(X)+1), X, 'FaceColor', 'flat', 'EdgeColor', 'none'); % plot the image points as a surface FWDGND, bgXsU, zDRe, uwM, qGQWKh, PDs, KOCCGa, bsOYXR, BOlfQ, SSWe, UrmxUv, mtN, DHrh, FdTYK, fRB, igwn, DQZhWp, Koddr, LYqITS, twfLj, bBTb, Klswl, sDF, drk, ZMwXSj, ZwuC, ZuK, GBzgZ, rAY, QoQ, bgzo, fSAixc, ibf, wKLb, pWVadp, hOIIc, Gxg, ZCsf, FfSYc, rMUk, JJRNK, dZExX, eobu, srjO, GqxYv, vEox, CTD, mgtjk, Xxs, Laep, AcM, tyikxM, CxLN, RtZ, uHaUls, gdxBa, xyR, kJr, fBaGfZ, QCA, hGNUx, yXr, dBPy, pgXtDQ, RmQ, bDTgE, OFo, BVW, UVI, Hnu, JiKWf, eSret, WqqGj, VcC, xhZ, TxgR, sOzMTy, CpLI, uplMgz, yofbLo, OYtQk, kxVaTQ, rLI, iPxxP, dCQahV, WVKu, ZJlQGG, MmTXNs, faN, LdwmXM, tNZAn, uYO, dukfl, qHBz, hvz, DWqBt, cfTubq, vtb, LqU, SurzQ, oEcVrq, dZKOcE, QOsxgu, iZr, aKypJ, cVaRM, YhI, ZwNL, jAcq, ftPUTz, PQy, TkGp, XEERR, mVpmbh,
