matplotlib.pyplot.scatter()函式用法

參考地址:https://matplotlib.org/api/_as_gen/matplotlib.pyplot.scatter.html?highlight=scatter#matplotlib.pyplot.scatter

 

函式原型:matplotlib.pyplot.scatter(xys=Nonec=Nonemarker=Nonecmap=Nonenorm=Nonevmin=Nonevmax=Nonealpha=Nonelinewidths=None

verts=Noneedgecolors=None*data=None**kwargs)

 

引數解釋:x,y:資料座標

     s:散點的大小

                  c:散點的顏色 如果輸入int就會自動生成指定數量種類的顏色給散點顯示 如c=3就會生成3種不同顏色的散點

                  marker:散點的形狀,引數對應表如下:

marker symbol description
"." m00 point
"," m01 pixel
"o" m02 circle
"v" m03 triangle_down
"^" m04 triangle_up
"<" m05 triangle_left
">" m06 triangle_right
"1" m07 tri_down
"2" m08 tri_up
"3" m09 tri_left
"4" m10 tri_right
"8" m11 octagon
"s" m12 square
"p" m13 pentagon
"P" m23 plus (filled)
"*" m14 star
"h" m15 hexagon1
"H" m16 hexagon2
"+" m17 plus
"x" m18 x
"X" m24 x (filled)
"D" m19 diamond
"d" m20 thin_diamond
"|" m21 vline
"_" m22 hline
0 (TICKLEFT) m25 tickleft
1 (TICKRIGHT) m26 tickright
2 (TICKUP) m27 tickup
3 (TICKDOWN) m28 tickdown
4 (CARETLEFT) m29 caretleft
5 (CARETRIGHT) m30 caretright
6 (CARETUP) m31 caretup
7 (CARETDOWN) m32 caretdown
8 (CARETLEFTBASE) m33 caretleft (centered at base)
9 (CARETRIGHTBASE) m34 caretright (centered at base)
10 (CARETUPBASE) m35 caretup (centered at base)
11 (CARETDOWNBASE) m36 caretdown (centered at base)
"None"" or ""   nothing
'$...$' m37 Render the string using mathtext. E.g "$f$" for marker showing the letter f.
verts   A list of (x, y) pairs used for Path vertices. The center of the marker is located at (0,0) and the size is normalized, such that the created path is encapsulated inside the unit cell.
path   Path instance.
(numsides, style, angle)  

The marker can also be a tuple (numsides, style, angle), which will create a custom, regular symbol.

numsides:
the number of sides
style:

the style of the regular symbol:

  • 0: a regular polygon
  • 1: a star-like symbol
  • 2: an asterisk
  • 3: a circle (numsides and angle is ignored); deprecated.
angle:
the angle of rotation of the symbol

    cmap:指定顏色對映

    norm,vmin,vmax..:都是亮度,外觀相關設定詳見頂部網址。
