show partically blokced x-axis

This code shows a partically blocked x-axis, because of the statement "ylim(yl)" trimming the y-axis limit. How do I make the x-axis show? Thanks.

[Walter Roberson]

Which code? And please expand on what you mean by "a partially blocked x-axis" ?

My appology, here is the code:

clc;

close all;

clear all;

workspace; % Display workspace panel.

% Generate some sample data

data = 2.5 * sin((1:20)/2) +5;

% Plot the data so we can get the y limits

% so we know where to put gray backgrounds.

% hBars = bar(data);

hBars = plot(data);

yl = ylim;

%set(hBars, 'BarWidth', 1);

x = get(hBars, 'XData');

set(gcf, 'Position', get(0,'Screensize')); % Maximize figure.

% Define the recession where we'll have a gray background.

recession = data < 4;

hold on;

grayColor = [1 1 1] * 0.8; % Adust to change lightness of the gray.

% Plot gray bars going down.

hBarsDown = bar(yl(1) * recession, ...

'FaceColor', grayColor, 'BarWidth', 1, 'lineStyle', 'none');

% Plot gray bars going Up.

hBarsUp = bar(yl(2) * recession, ...

'FaceColor', grayColor, 'BarWidth', 1, 'lineStyle', 'none');

% Plot main bars.

% hBars = bar(data, 'FaceColor', 'b', 'BarWidth', 1);

axis manual

ylim(yl);

hBars = plot(data);

Quick fix: set(gca,'Layer','top')

Cheap'n'dirty -- that's me :)

Hi Hugh,

This is because the axis mode is still 'Auto'. I would suggest you to do the following when adjusting the y axis

axis manual
ylim(yl)

Honglei, adding axis manual did not work. Here is the full code, your help is much appreciated. - Hugh

Saved me hours. Great, thanks Matt.

Yay. Love it when the cheap tricks work :)
