truncAxis (break X/Y axis | 截断坐标轴)

Create broken axes by truncating X and/or Y axis, supporting logarithmic scaling and reversed axis and resizing the axes based on X/Y range.

Basic usage

• truncAxis(gca, 'X', [x1, x2])
• truncAxis(gca, 'Y', [y1, y2])
• truncAxis(gca, 'X', [x1, x2], 'Y', [y1, y2])

Where:

• x1, x2: break points on X-axis, satisfying XLim(1) < x1 < x2 < XLim(2)
• y1, y2: break points on Y-axis, satisfying YLim(1) < y1 < y2 < YLim(2)

Demo 1

X = linspace(0, 2*pi, 100);
Y = exp(.3*X).*sin(3*X);
scatter(X, Y, 'LineWidth',1);

set(gca, 'Box','on', 'NextPlot','add', 'LineWidth',1.5, ...
    'FontName','Times New Roman', 'FontSize',15, ...
    'XLim',[0, 6], 'YLim',[-6, 6], 'XColor','r','YColor','b', ...
    'XMinorTick','on', 'YMinorTick','on', 'TickDir','out', 'TickLength',[.005,.001]);

truncAxis('X',[4, 4.5], 'Y',[2, 3], 'XResize','on', 'YResize','on')

Demo 2

% Generate sample data
Data = [randi([20, 35], [5, 1]), randi([160, 190], [5, 1])];
err = rand([5, 2]) .* 5;

hold on
barHdl = bar(Data, 'BarWidth', 1, 'LineWidth',1);

% Customize bar colors and transparency
barHdl(1).FaceColor = [153, 153, 253] ./ 255;
barHdl(2).FaceColor = [255, 153, 154] ./ 255;
barHdl(1).FaceAlpha = 0.9;
barHdl(2).FaceAlpha = 0.9;

% Render and customize error bars
errorbar(barHdl(1).XEndPoints, Data(:, 1), err(:, 1), ...
    'LineStyle', 'none', 'Color', 'k', 'LineWidth', 1);
errorbar(barHdl(2).XEndPoints, Data(:, 2), err(:, 2), ...
    'LineStyle', 'none', 'Color', 'k', 'LineWidth', 1);

% Axes styling and label customization
ax = gca;
ax.YLim = [0, 200];
ax.LineWidth = 1;
ax.TickLength = [0.005, 0.001];
ax.Box = 'on';
ax.FontSize = 13;
ax.XTick = 1:5;
ax.XTickLabel = {'A', 'B', 'C', 'D', 'E'};

axMat = truncAxis('Y', [50, 155]);
axMat(1).Children(end).BaseLine.Color = 'none';

% Add legend
legend({'AAAAA', 'BBBBB'}, 'FontSize', 13);
