Hi Olaf,
When using logarithmic scales and reversing the Y-axis, MATLAB's automatic tick placement can sometimes lead to overlapping ticks or misaligned labels. Here are some strategies to ensure your XTickLabels are placed correctly without overlapping the ticks:
Approach
- Manual Tick Placement: Specify the X-ticks manually to ensure they are placed at appropriate positions.
- Adjust XTickLabel Position: Use the XTickLabel property to manually set the labels if necessary.
- Increase Figure Size: Sometimes increasing the figure size can help in reducing overlap.
Here's how you can implement these strategies in your code:
x = [1e-5:0.5:100];
y = x;
% Create the first subplot
subplot(3,1,1);
plot(x, y);
set(gca, 'XScale', 'log', 'YDir', 'reverse', 'TickDir', 'in', 'fontsize', 14);
title("set(gca,'XScale','log','YDir','reverse','TickDir','in')");
% Manually setting X-ticks
xticks([1e-5, 1e-3, 1e-1, 1, 10, 100]);
xticklabels({'10^{-5}', '10^{-3}', '10^{-1}', '1', '10', '100'});
% Create the second subplot
subplot(3,1,2);
plot(x, y);
set(gca, 'XScale', 'log', 'YDir', 'reverse', 'TickDir', 'out', 'fontsize', 14);
title("set(gca,'XScale','log','YDir','reverse','TickDir','out')");
% Manually setting X-ticks
xticks([1e-5, 1e-3, 1e-1, 1, 10, 100]);
xticklabels({'10^{-5}', '10^{-3}', '10^{-1}', '1', '10', '100'});
% Create the third subplot
subplot(3,1,3);
plot(x, y);
set(gca, 'YDir', 'reverse', 'TickDir', 'in', 'fontsize', 14);
title("set(gca,'YDir','reverse','TickDir','in')");
% Manually setting X-ticks
xticks([1e-5, 1e-3, 1e-1, 1, 10, 100]);
xticklabels({'10^{-5}', '10^{-3}', '10^{-1}', '1', '10', '100'});
Explanation
- Manual X-Ticks: By using xticks and xticklabels, you have precise control over where the ticks and labels are placed. This helps prevent overlapping and ensures clarity.
- Logarithmic Labels: Using LaTeX-style labels (e.g., '10^{-5}') can make the tick labels more readable and consistent with logarithmic scales.
- Consistency Across Subplots: Ensure that each subplot has the same tick settings for consistency.
By following these steps, you should be able to achieve a clear and well-aligned plot with logarithmic scales and reversed axes.
