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')

ax = gca;
ax.YAxis.Exponent = 0;
