Shading an area across zero
显示 更早的评论
I have a plot of zscores and would like to highlight a particular area of the graph. This is the relevant code i'm using:
xmin = plot_time-time_period; xmax = plot_time; %called from a matrix
x = [xmin xmax];
yLimits = get(gca,'YLim');
h1 = area(x,[yLimits(1) yLimits(1)]);
h2 = area(x,[yLimits(2) yLimits(2)]);
set(h1,'Facecolor','k')
set(h2,'Facecolor','k')
alpha(0.15)
Which produces this:
I would like to remove the line across zero, but the following code just creates nonsense:
h1 = area(x,[yLimits(1) yLimits(2)]);
Any ideas? Thanks.
