问题 I am trying to add a timer a simulation i am working on. At the moment i can get the timer to display in the location i want, however i cant make the numbers clear each other, i.e they all just stack on top of each other slowly creating a solid black mess. I have tried implementing a clf function but it just clears the entire figure. The code for the timer is: HH = 0; MM = 0; SS = 0; timer = sprintf('%02d:%02d:%02d',HH,MM,SS); text(-450,450,timer); %% adjust location of clock in graph using

问题 I have just started using seaborn to produce my figures. However I can't seem to remove one of the legends produced here. I am trying to plot two accuracies against each other and draw a line along the diagonal to make it easier to see which has performed better (if anyone has a better way of plotting this data in seaborn - let me know!). The legend I'd like to keep is the one on the left, that shows the different colours for 'N_bands' and different shapes for 'Subject No' ax1 = sns.relplot(y

问题 I am trying to produce a figure in MATLAB with a popupmenu that changes the axes of a subplot. This works so far. But when saving the figure using File > Save, my handles get deleted and it shows me the following error message: Error using struct2handle Error while evaluating uicontrol CreateFcn Error using handle.handle/set Invalid or deleted object. Error in popup_test/mimi (line 33) set(h1,'XData', [0,8],'YData',[0,8]) Error while evaluating uicontrol Callback It appeares, that when saving

问题 I'm trying to plot several symbolic functions in the same subplot. Using ezsurf makes it easy to plot symbolic functions, but it doesn't seem to be very configurable. I can't colour the individual graphs (see the figure below). They all automatically take the normal jet colourmap. How can they use different colormaps? edit : Here's the new code I'm running using freezeColors as suggested in the answer: subplot(2,2,4) for i = 1:numClasses f(i) = M_k(i)/sum(M_k); freezeColors hold on ezsurfc(x

问题 I am currently running a Matlab script (below) which produces four seperate graphs. I want to combine two of these graphs so that the are displayed simultaneously. The graphs I wish to combine i referred to as FIGURE 2 and FIGURE 4 in the below script. The only input to the script is a txt file with 6 columns: x coordinates, y-coordinates and 4 variables (Depth [m], Hsig [m] , Period [sec] , Dir [degrees]) Any help on this would be greatly appreciated. % Post-process a SWAN wave model output

问题 I have, what I think might be a 'simple' problem. I know how to change the color of a MATLAB title. What I do not know, is how to use two different colors, at two different parts of the title. For example, lets say the title of a figure said "Hello World". Then, I want the "Hello" to be in black, while the "World" to be in blue. How to do this? Thank you. 回答1: You can use TeX markup to do that. Here's an example: title(['Hello {\color{blue}World}']); 回答2: % Create text text('Parent',axes1,...

问题 I'm trying to change some implay options before opening the figure. The options I want to change are "Maintain Fit to window" and "range for image pixel intensities" which is at Tools >Colormap . The answer Matlab - implay's default size window is very helpful for beginning. However I am very new at GUI environment in MATLAB. After following the site's instructions, the code is below shows the colormap menu object. close all force implay(zeros(100,100,100)) whole_objs = findall(0); whole_objs

问题 I currently have code like the following: import os import numpy as np import pylab import matplotlib.pyplot as plt import matplotlib.cm as cm from matplotlib.patches import Polygon import numpy as np ... # Read my image img = matplotlib.image.imread(p_image) # Render it, move the coordinates' origin to the upper left corner plt.imshow(np.flipud(img), cmap=cm.Greys_r,origin='upper') # Overlay a polygon p = Polygon( zip(xs,ys), alpha=0.2) plt.gca().add_artist(p) # Save it to disk plt.savefig(p

问题 I have this matlab GUI (not made by me of course), and I have been looking everywhere for almost about a week on how I can possibly extract the figures from it to no success. I am at my wits end and was wondering if any one could help? I want to be able to copy the figure (and save to desktop to extract data from after), or copy the data in a form of a matrix that I can manipulate and save. I thought I'd put the GUI here in case anyone wants to give it a shot and help (I'd be willing to

问题 Sorry to bother you with what is for sure a very simple mistake, but I still cannot figure it out by myself: library(ggplot2) X = rep(c(1:6),3) Y = rep(c(1:6),3) group = rep(c(1:3), each = 6) data = data.frame(X = X, Y = Y, group = group) ggplot(data, aes(x = X, y = Y, group = group)) + geom_point() I do not get any output from this, no figure is created. What am I doing wrong here? Thanks a lot in advance! Gero 回答1: Try print the plot if you are calling it from another function or in Shiny:
