Rotate axis tick labels
This works for me: plt.xticks(rotation=90)

Curve Fitting to a time series in the format ‘datetime’?
Instead of plotting datenums, use the associated datetimes. import numpy as np import matplotlib.pyplot as plt import matplotlib.dates as mdates import datetime as DT import time dates = [DT.datetime(1978, 7, 7), DT.datetime(1980, 9, 26), DT.datetime(1983, 8, 1), DT.datetime(1985, 8, 8)] y = [0.00134328779552718, 0.00155187668863844, 0.0039431374327427, 0.00780037563783297] yerr = [0.0000137547160254577, 0.0000225670232594083, 0.000105623642510075, 0.00011343121508] x = mdates.date2num(dates) … Read more
Show decimal places and scientific notation on the axis
This is really easy to do if you use the matplotlib.ticker.FormatStrFormatter as opposed to the LogFormatter. The following code will label everything with the format ‘%.2e’: import numpy as np import matplotlib.pyplot as plt import matplotlib.ticker as mtick fig = plt.figure() ax = fig.add_subplot(111) x = np.linspace(0, 300, 20) y = np.linspace(0,300, 20) y = … Read more
How to increase/reduce the fontsize of x and y tick labels
You can set the fontsize directly in the call to set_xticklabels and set_yticklabels (as noted in previous answers). This will only affect one Axes at a time. ax.set_xticklabels(x_ticks, rotation=0, fontsize=8) ax.set_yticklabels(y_ticks, rotation=0, fontsize=8) Note this method should only be used if you are fixing the positions of the ticks first (e.g. using ax.set_xticks). If you … Read more
Matplotlib showing x-tick labels overlapping
Ok, finally got it working. The trick was to use plt.setp to manually rotate the tick labels. Using fig.autofmt_xdate() did not work as it does some unexpected things when you have multiple subplots in your figure. Here’s the working code with its output: for i, d in enumerate([360, 30, 7, 1]): ax = axes.flatten()[i] earlycut … Read more
Show decimal places and scientific notation on the axis of a matplotlib plot
This is really easy to do if you use the matplotlib.ticker.FormatStrFormatter as opposed to the LogFormatter. The following code will label everything with the format ‘%.2e’: import numpy as np import matplotlib.pyplot as plt import matplotlib.ticker as mtick fig = plt.figure() ax = fig.add_subplot(111) x = np.linspace(0, 300, 20) y = np.linspace(0,300, 20) y = … Read more
How to display all x labels in R barplot?
You may be able get all of the labels to appear if you use las=2 inside the plot() call. This argument and the others mentioned below are described in ?par which sets the graphical parameters for plotting devices. That rotates the text 90 degrees. Otherwise, you will need to use xaxt=”n” (to suppress ticks and … Read more
