If ‘variable1’ and ‘variable2’ are strings, this works:
variable1 = 'Velocity';variable2 = 'Position';figure(1)scatter(rand(10,1), rand(10,1), 'bp')title(sprintf('“My Title“ %s %s', variable1, variable2))See this demo:
% Code to plot data, plus points interpolated in between the data.
clc; % Clear the command window.
clearvars;close all; % Close all figures (except those of imtool.)
workspace; % Make sure the workspace panel is showing.
format long g;format compact;fontSize = 22;% Make up sample data.
numOriginalPoints = 20;xOriginal = sort(100 * rand(1, numOriginalPoints), 'ascend');yOriginal = 30 * rand(1, numOriginalPoints) - 10;% Plot them
subplot(3, 1, 1);plot(xOriginal, yOriginal, 'ro-', 'LineWidth', 2);grid on;xlabel('X', 'FontSize', fontSize);ylabel('Y', 'FontSize', fontSize);title('Training Points', 'FontSize', fontSize);% Interpolate points in between, linearly from the min to the max.
numNewPoints = 100;xInterpolated = linspace(min(xOriginal), max(xOriginal), numNewPoints);yInterpolated = interp1(xOriginal, yOriginal, xInterpolated);% Plot interpolated points.
subplot(3, 1, 2);plot(xInterpolated, yInterpolated, 'bo-', 'LineWidth', 2);% Plot training points over them so we can see where they are in relation to the new points.
hold on;plot(xOriginal, yOriginal, 'ro', 'LineWidth', 2);grid on;title('Interpolated Points without Including Training Points', 'FontSize', fontSize);xlabel('X', 'FontSize', fontSize);ylabel('Y', 'FontSize', fontSize);legend('Interpolated', 'Training');% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0, 0.04, 1, 0.96]);% Note, if you want the original points included in the set of new, interpolated points,
% Add them to xInterpolated list.
subplot(3, 1, 3);xInterpolated = sort([xInterpolated, xOriginal], 'ascend');yInterpolated = interp1(xOriginal, yOriginal, xInterpolated);% Plot interpolated points.plot(xInterpolated, yInterpolated, 'bo-', 'LineWidth', 2);% Plot training points over them so we can see where they are in relation to the new points.hold on;plot(xOriginal, yOriginal, 'ro', 'LineWidth', 2);grid on;xlabel('X', 'FontSize', fontSize);ylabel('Y', 'FontSize', fontSize);title('Interpolated Points Including Training Points', 'FontSize', fontSize);legend('Interpolated', 'Training');% Enlarge figure to full screen.set(gcf, 'Units', 'Normalized', 'OuterPosition', [0, 0.04, 1, 0.96]);
