Hi all,

I am plotting my graph use loglog(x,y) and my setting for the log plot is shown below, but that does not provide the output I need as shown as in the figures. I can obtained the log scale for y-axis easily but I have problem to get the log scale for x-axis with a step of 5.

Thank you for you helps. I truly appreciate it.

loglog(x,y);
set(gca,'XLim',[0 30]);
set(gca,'YLim',[1e-1 1e1]);
set(gca,'XTick',10.^(0:1));
set(gca,'YTick',10.^(-1:1));
set(gca,'XMinorTick','on','YMinorTick','on')

hello

suggestion below :

x = (0.1:0.1:50);
y = 0.1+0.1*exp(0.1*x);
xmax= 30;
dx = 5;
loglog(x,y);
set(gca,'XLim',[1e-1 xmax]);
set(gca,'YLim',[1e-1 1e1]);
set(gca,'XTick',[1e-1 1 (dx:dx:xmax)]);
set(gca,'YTick',10.^(-1:1));
set(gca,'XMinorTick','on','YMinorTick','on')
