loglog plot

Community matplotlib-users

Hi,

I have a few questions about the loglog plot :

1- Is there a way to a have axis format with real numbers rather than
numbers with exponent ?

2- I would like to have a grid not only for 10^2, 10^3, 10^4, 10^5 ... but
also for the minor axis ticks. is it possible ?

3- I use loglog to plot parallel lines. How can I have the function label
directly displaid next to the plotted straight lines ?

Thanks for your tips.

Hi,

I have a few questions about the loglog plot :

1- Is there a way to a have axis format with real numbers rather than

numbers with exponent ?

import matplotlib.pyplot as plt
ax1 = plt.gca()
ax1.yaxis.set_major_formatter(ticker.FormatStrFormatter("%.2f"))

You can check formatting options from http://docs.python.org/library/stdtypes.html#string-formatting-operations

2- I would like to have a grid not only for 10^2, 10^3, 10^4, 10^5 … but

also for the minor axis ticks. is it possible ?

You can use plt.yticks() to get new ticks as well as grids. Do you know how to make ticklabels like 5x10^2 etc…? This I couldn’t figure yet.

3- I use loglog to plot parallel lines. How can I have the function label

directly displaid next to the plotted straight lines ?

Thanks for your tips.

plt.text and some fine-tuning?

You are welcome. My response to your 2nd question is still unknown, also I have another question. Anyone knows how to achieve that?

Thanks.
