以xticks爲例:html
matplotlib.pyplot.xticks(*args, **kwargs)
獲取或者設置當前刻度位置和文本的 x-limits:api
# return locs, labels where locs is an array of tick locations and # labels is an array of tick labels. locs, labels = xticks() # set the locations of the xticks xticks( arange(6) ) # set the locations and labels of the xticks xticks( arange(5), ('Tom', 'Dick', 'Harry', 'Sally', 'Sue') )
關鍵字 args
,若是有其餘的參數則是 Text 屬性。例如,旋轉長的文本標註。this
xticks( arange(12), calendar.month_name[1:13], rotation=17 )
matplotlib.axis.Axis對象負責刻度線、格網線、刻度標註和座標軸標註的繪製工做。你能夠設置y軸的左右刻度或者x軸的上下刻度。 Axis
也存儲了用於自動調整,移動和放縮的數據和視覺間隔;同時 Locator 和 Formatter 對象控制着刻度的位置以及以怎樣的字符串呈現。code
每個 Axis
對象包含一個 label
屬性以及主刻度和小刻度的列表。刻度是 XTick 和 YTick 對象,其包含着實際線和文本元素,分別表明刻度和註釋。由於刻度是根據須要動態建立的,你應該經過獲取方法 get_major_ticks() 和 get_minor_ticks()以獲取主刻度和小刻度的列表。儘管刻度包含了全部的元素,而且將會在下面代碼中涵蓋,Axis
方法包含了獲取方法以返回刻度線、刻度標註和刻度位置等等:orm
In [285]: axis = ax.xaxis In [286]: axis.get_ticklocs() Out[286]: array([ 0., 1., 2., 3., 4., 5., 6., 7., 8., 9.]) In [287]: axis.get_ticklabels() Out[287]: <a list of 10 Text major ticklabel objects> # note there are twice as many ticklines as labels because by # default there are tick lines at the top and bottom but only tick # labels below the xaxis; this can be customized In [288]: axis.get_ticklines() Out[288]: <a list of 20 Line2D ticklines objects> # by default you get the major ticks back In [291]: axis.get_ticklines() Out[291]: <a list of 20 Line2D ticklines objects> # but you can also ask for the minor ticks In [292]: axis.get_ticklines(minor=True) Out[292]: <a list of 0 Line2D ticklines objects>
