How to change the degree range on a plot?

How to change from -10 degrees to 10 degrees on the x-axis?

end

set(gca,'xticklabel',xt1);

% degree symbol in x-axis - END

set(gca,'colororder',parula(16)) % to avoid color repetition in plotting lines

ylim([0 0.2])

yticks(0:0.2:0.2)

xticks(-10:10:10)

xlim([-10 10]) % How to change from -10 degrees to 10 degrees on a x-axis?

Hi @Arkadiusz Charuk

From the description, I understand that you want to adjust the x-axis limits from -50 to +50 to -10 to +10.

Here, I have attached one workaround to achieve this. (Since I don't have the "L_18" matrix, I've generated random data instead.)

% Generate random data
x = linspace(-20, 20, 100); % x values from -20 to 20
y = 5 * randn(1, 100); % Random y values, scaled for better visibility

% Create the figure and plot
figure('Name', 'Random Data Displayed with Limited X-Axis Range')
plot(x, y, 'LineWidth', 1.5)
set(gcf, 'Position', [200, 200, 400, 300]) % X pos, Y pos, X size, Y size
set(gca, 'FontSize', 9, 'FontName', 'Times New Roman') % Size font axis
grid on

% Add degree symbol to x-axis labels
xticks(-10:5:10) % Set x-axis ticks from -10 to 10
xlim([-10 10]) % Limit x-axis to -10 to 10

% Update x-axis tick labels to include degree symbol
xt = get(gca, 'XTick');
xt1 = arrayfun(@(val) sprintf('%d°', val), xt, 'UniformOutput', false);
set(gca, 'XTickLabel', xt1);

% Set y-axis limits for better visualization
ylim([-15 15]) % Adjust as needed for your data

Here I have used “arrayfun” to update the “xticks”.
