Hello!

I have an "example" regression loglog graph to show someone. The Y axis is not very large, but is less than 1, so it shows up as log rather than linear.

Is there a way to do this cleanly? Here's the code:

% reggie
rng('shuffle');
Intercept   = 1000;
Slope       = -1.6;
dist        = 150:50:300;
vib         = Intercept*(dist.^Slope);
minx        = 50;
maxx        = 400;
figure
loglog(dist,vib,'o','MarkerFaceColor','r')
xlim([minx maxx])
ylim([0.05 1])
hold on
grid on
grid minor
loglog([minx maxx],[Intercept*(minx^Slope) Intercept*(maxx^Slope)],'--');
xlabel('Distance (ft)');
ylabel('Vibration (in/s)');
title('Regression Example');
for n = 1:length(dist)
  scatterling   = 0.3 * vib(n);
  median_value  = vib(n);
  new_values    = scatterling.*randn(6,1)+median_value;
  loglog(dist(n),new_values,'diamond','LineStyle','none');
end
newdist = 100;
reduction_factor = 0.65;
newvib = (reduction_factor * Intercept) *(newdist.^Slope);
loglog(newdist,newvib,'o','MarkerFaceColor','b');
scatterling = 0.4 * newvib;
median_value = newvib;
new_values    = scatterling.*randn(6,1)+median_value;
  loglog(newdist,new_values,'diamond','LineStyle','none','MarkerFaceColor','g'); 
  

Thanks!

Doug

It is not clear what you are asking for??

You do loglog plots. If you do not want to reprogram that to linear, you could

set(gca, 'YScale', 'linear')

Thank you Walter.

I would like the scale to be logarithmic, but the label to be linear. For this case, it's basically from 0.05 to 1.0. So there wouldn't be a lot of points, but as it is, I get two labels: 10 superscript -1 and 10 superscript 0.

Thanks!

Doug
