![]() If =size(z), then length(y) must be M and length(x) must be N.The x and y arguments of surf must match the dimensions of the z argument.Shading interp changes how the colors are applied from a discrete to grid to a continuous grid. We will use a bivariate gaussian pdf with mean 0 and covariance. In the next graphics (surf, mesh contour) tools all plot a matrix of z data against vector of x and y data. Title('Scatter plot of correlated normal random variables') įormatting, such as color or market shape can only be changed by either using handle graphics or manually editing the plot. It produces a scatter plot of the elements of a vector x against the elements of a vector y. With “figure(2)” we are creating a new figure graphics object where to plot. Plot3 plots a series against two other series in 3-space. If we type only plot(y), it will plot the data in vector y against a simple series which labels each observation 1, 2. If not use format string MATLAB will automatically create on. ![]() ’g:’, will produce a green dotted line with no symbol, use the format string.’r+ ’, will produce a set of red + symbols at every data point,Īrguments which are not needed can be left out.’gs-’, will produce a green solid line with squares at every data point,.We can combine this three to form a format string, for instance: linespec can be any of – solid, : dotted,.shape can be any of o circle, x x-mark, + plus, * star, s square, d diamond, v triangle (down), ^ triangle (up), triangle (right), p pentagram, h hexagram.color can be any of b blue, g green, r red, c cyan, m magenta, y yellow, k black.Where xi and yi are vector of the same size and format i is a format string of the form color shape linespec. axis can also be used to tighten the axes to include only the minimum space required to express the data using the command axis tight.The axis can be changed by calling axis() where the z-variables are only allowed if the figure is 3D.AX will be a row vector of the form where zlow and zhigh are only included if the figure is 3D. To retrieve the current axis limits, enter AX = axis().axis, axis can be used to both get the axis limits and set the axis limits.xlabel, ylabel and zlabel produce text labels on the x, y and if present z axes respectively, standard.title,title of graph, title (’Figure Title’). ![]() legend,labels the various elements on a graph, legend(’Series 1’,’Series 2’).These four are the most important, there are many more. TimeInReqFrmat=datestr(Time(:,1),'HH:MM:SS'), but this gives me a string of characters.We explore now the basic functions of graphics in MATLAB. ![]() How do I have to modify the program to convert the x-axis into hh:mm format do this job? This actually corresponds to 16:48:00 to 17:48:00 and similarly for the second one. Now, when I plotting, the x axis starts from 16.8 to 17.8 for first figure and 16.8 and 18.8 for second figure. The xaxis is time and y axis is some other quantity, lets say field. The result of this plot is these two figures: =spectrogram(Field,window,noverlap,nfft,fs,'yaxis') Window=hamming(hammng_wndw_size) %window size I have a code which goes like this: clc clear close allįigure('units','normalized','outerposition',)
