Total running time of the script: (0 minutes 1. Specify two return arguments to store the text objects for the title and subtitle. Use the 'Color' name-value pair argument to customize the color for both lines of text. Here's an example of how you can do it: plot (1:10, rand (1, 10), 'r') Plot a random line in red hold on plot (1:10, rand (1, 10), 'b') Plot a. Then create a title and a subtitle by calling the title function with two character vectors as arguments. Then you can change their text colors separately. text ( i + 0.4, 0.85, f " ', ** text_args ) for g in range ( n_groups ): ax. To change the legend text colors individually, you have to first get the handles to the text objects, which are children of the legend object. subplots ( figsize = ( 6.5, 1.65 ), layout = 'constrained' ) ax. Of course the code can be compacted once you understand the main flow.Import matplotlib.pyplot as plt from matplotlib.patches import Rectangle import numpy as np fig, ax = plt. %% Find indices of vectors for each category % define any color you want for each category % it the natural style (also can use "plot(x,Y)" this way) Y = Y.' % Matlab is column major so transposed the matrix to have Use dot notation to refer to a particular object and property: plot (rand (3)) lgd legend ('a','b','c') c lgd.TextColor lgd. By changing property values, you can modify certain aspects of the legend. X = 1:size(Y,2) % just defined to be able to use the notation "plot(x,Y)" Legend properties control the appearance and behavior of a Legend object. One way of doing it: %% Sample input data Specify Different Sets of Colors and Line Styles The colors MATLAB selects come from the axes ColorOrder property, which contains a three-column matrix of colors specified as RGB triplets. Once you have that, you plot the lines by groups (belonging to the same category) and assign their reserved color. If you want to specify a color or a line style for a specific item in a plot, see Specify Plot Colors and Specify Line and Marker Appearance in Plots. You need to scan the category column (your z variable) and find the indices of the lines which belong to each category. So, sample 1 and 3 should be the same colour X can just be the column number Sample 1. The expected outcome is a plot, where each sample of the same group in z is the same colour. I know that in R I would be able to just do something of the form matplot(x, y, color = z)īut I have no experience with matlab, hence the confusion. Many visualization tools allow us to specify the color. So far, I have tried plot(x, y, 'color', z)Īll guides I have found online give similar methods, none of which work. MATLAB generates plots using a standard color scheme however, we can change the colors as required. I am trying to plot this such that each sample in the same category is the same colour, but is yet to work.Īn example of what z looks like is (A, B, C, A, C, B. I have a matrix with 24 samples and 10,000 datapoints x each with different intensities y which I am able to plot in a line plot doing plot(x,y), however I have a third variable z (24x1) which is categorical.
