抑制图形记号中的指数格式

一种更好地控制记号标签并避免指数格式的方法是使用 TICK2TEXT 从文件交换。

举个例子:

y = cool(7); %# define some data
ah = axes; %# create new axes and remember handle
bar3(ah,y*1E6,'detached'); %# create a 3D bar plot
tick2text(ah, 'ztickoffset' ,-1.15,'zformat', '%5.0f', 'axis','z') %# fix the tick labels

根据这个 technical solution page

y = cool(7);
bar(y(:,1)*1e6)
set(gca, 'YTickMode','manual')
set(gca, 'YTickLabel',num2str(get(gca,'YTick')'))

但是,在Z轴上似乎有一个bug(标签格式正确,但指数乘数由于某些原因仍在显示!)

y = cool(7);
bar3(y*1e6, 'detached')
set(gca, 'ZTickMode','manual')
set(gca, 'ZTickLabel',num2str(get(gca,'ZTick')'))

最后,还有另一种解决方法,我们用文本对象替换记号标签(参见此图) technical solution page 作为参考):

y = cool(7);
bar3(y*1e6, 'detached')
offset = 0.25; Xl=get(gca,'XLim'); Yl=get(gca,'YLim'); Zt=get(gca,'ZTick');
t = text(Xl(ones(size(Zt))),Yl(ones(size(Zt)))-offset,Zt, num2str(Zt')); %#'
set(t, 'HorizontalAlignment','right', 'VerticalAlignment','Middle')
set(gca, 'ZTickLabel','')

LOG10 帮助您根据打印的值自动计算适当的比例因子。假设你的数据是变量 x 和 y

scale = 10^floor(log10(max(y)));  %# Compute a scaling factor
plot(x,y./scale);                 %# Plot the scaled data
yTicks = get(gca,'YTick');        %# Get the current tick values
set(gca,'YTickLabel',num2str(scale.*yTicks(:),'%.2f'));  %# Change the labels
