Hi,
I have a problem regarding bining x axis in a plot.
I have an array that I want to plot it. In biochemistry is cardinality of reactions.
Then my boss asked me:
"x axis should be binned and put into log10 scale to show linear relationship. I think you need to create bins on the x scale, equally spaced in log scale, then the value of each bin is the number of reactions with cardinality between an interval on log scale. This code may help...
https://uk.mathworks.com/matlabcentral/fileexchange/27176-log-binning-of-data.
But I do not know how to plot is in the way that we see linearity with bining x logarithmly?
I would be appricaite if someone could guide me?
Best regards,
Susan

You mean this?
x = log10(1:n);
plot(x,s)

No, I do not think so. Becasue it does not show something linear.I guess he means something like figure 5 in this link https://arxiv.org/pdf/1011.1533.pdf
But I do not know how to get that.

Hi
Try replacing
plot(x,y)
to
semilogx(x,y)
‘semilogx’ turns the x-axis to a Logarithmic scale as in the figure that you provided in the above commented link. Further details can be got from this link:
https://www.mathworks.com/help/matlab/ref/semilogx.html
and for logarithmic scale on y-axis, use ‘semilogy’.
