Matlab中的坐标轴设置技巧
axisoff;
%去掉坐标轴
axistight;
%紧坐标轴
axisequal;
%等比坐标轴
axis([-0.1, 8.1, -1.1, 1.1]);
% 坐标轴的显示范围
x = -pi/2:0.01:pi;
plot(x,sin(x))
%先绘制个基本图形
% gca: gca, h=figure(...);
set(gca,
'XLim',[-pi/2pi]);
%X轴的数据显示范围
set(gca,'XTick',[-pi/2:pi/4:pi]);
%X轴的记号点
set(gca,'XTickLabel',{'-pi/2' '-pi/4:' '0'
'pi/4' 'pi/2' 'pi*3/4''pi'})
% X轴的记号
set(gca,'XGrid','on');
%X轴的网格
set(gca,'XDir','reverse');
%逆转X轴
set(gca,'XColor','red');
%X轴的颜色
set(gac,'Xscale','log')
% x轴以log
形式显示
xlim(min,max)

该文章讲述了matlab画图设置图片大小以及线宽和字号命令.
set(gcf,'Units','centimeters','Position',[1010 7
5]);%设置图片大小为7cm×5cm
%get hanlde to current
axis返回当前图形的当前坐标轴的句柄,
%(the first element is the
relative distance of the axes
to the left edge ofthe
figure,...
%the second the vertical distance
from the bottom, and then
the width andheight;
set(gca,'Position',[.13 .17 .80
.74]);%设置xy轴在图片中占的比例
set(get(gca,'XLabel'),'FontSize',8);%图上文字为8
point或小5号
set(get(gca,'YLabel'),'FontSize',8);
set(get(gca,'TITLE'),'FontSize',8);
set(gca,'fontsize',8);
set(gca,'linewidth',0.5);
%坐标线粗0.5磅
set(gca,'box','off');%Controls the box around
the plotting area
set(get(gca,'Children'),'linewidth',1.5);%设置图中线宽1.5磅
