I am plotting the following chart :
with the following code:
fig, ax = plt.subplots(figsize=(20, 3))
mpf.candlestick_ohlc(ax,quotes, width=0.01)
ax.xaxis_date()
ax.xaxis.set_minor_locator(mpl.dates.HourLocator(interval=4) )
ax.xaxis.set_minor_formatter(mpl.dates.DateFormatter('%H:%M'))
plt.xticks(rotation = 90)
plt.grid(True)
plt.show()
I would like to also rotate the minor ticks: How would i do that?
Subsidiary question is there a way to rotate both major and minor tick with a single command?
您可以通过一行plt.setp(ax.xaxis.get_minorticklabels(), rotation=90)
的代码进行plt.setp(ax.xaxis.get_minorticklabels(), rotation=90)
。
While dealing with the problem myself, I discovered that you can also easily accomplish this with a single statement using the tick_params
:
ax.tick_params(axis="x", which="both", rotation=45)
This will rotate labels on your x axis
, and the which
option allows you to choose between minor, major or both. In case you have multiple plots you will have to do this for every plot in the figure.
By exploring a little, I discovered that ax.get_xminorticklabels()
is a list with a text
class element.
>>> print(type(ax.get_xminorticklabels()[0]))
<class 'matplotlib.text.Text'>
And text
can be rotated !
>>> for text in ax.get_xminorticklabels():
>>> text.set_rotation(90)
You only have to be careful that they do not overlap.
