繪圖函數(shù)列表

下面整理了幾乎所有matplotlib中的繪圖函數(shù)，及其在不同坐標(biāo)軸下的表現(xiàn)。

為DrawType添加這些繪圖函數(shù)

之所以閑得無(wú)聊總結(jié)matplotlib中的繪圖函數(shù)，是為了在Python繪圖系統(tǒng)中正確第調(diào)用它們。

有了這些繪圖類(lèi)別后，首先繪圖字典需要更新，這個(gè)字典不能做成全局變量，因?yàn)槠渲械腶x，其實(shí)是作為函數(shù)參數(shù)傳遞進(jìn)來(lái)的。

funcDct = {
    "點(diǎn)線圖"  : ax.plot,    "曲線圖" : ax.plot, 
    "散點(diǎn)圖"  : ax.scatter, 
    "圖像"    : ax.imshow,  "偽彩圖" : ax.pcolormesh, 
    "條形圖"  : ax.bar,     "橫向條形圖": ax.barh, 
    "莖葉圖"  : ax.stem,    "階梯圖": ax.step,
    "填充圖"  : ax.stackplot, 
    "誤差線"  : ax.errorbar, 
    "區(qū)間圖"  : ax.fill_between, "橫向區(qū)間圖": ax.fill_betweenx, 
    "曲面圖"  : ax.plot_surface, 
    "網(wǎng)格圖"  : ax.plot_wireframe,
    "三角面圖": ax.plot_trisurf,
    "等高線"  : ax.contour, "填充等高線" : ax.contourf,
    "向量場(chǎng)圖": ax.quiver,  "流場(chǎng)圖":ax.streamplot,
    "風(fēng)場(chǎng)圖"  : ax.barbs, 
    "直方圖"  : ax.hist,    "二維直方圖":ax.hist2d,
    "鉆石圖"  : ax.hexbin,  "信封圖"  : ax.enventplot, 
    "箱線圖"  : ax.boxplot, "小提琴圖":violinplot,
    "餅圖"    : ax.pie,
    "自由等高線" : ax.tricontour,
    "自由填充等高線" : ax.tricontourf,
    "自由偽彩圖" : ax.tricolor,
    "三角骨架圖" : ax.triplot
}

然后據(jù)此更新self.TYPES，

self.TYPES = [
    "點(diǎn)線圖", "曲線圖", "散點(diǎn)圖", "圖像", "偽彩圖" , 
    "條形圖", "橫向條形圖", "莖葉圖", "階梯圖", "填充圖", 
    "誤差線", "區(qū)間圖", "橫向區(qū)間圖",  "曲面圖",  
    "網(wǎng)格圖", "三角面圖", "等高線",  "填充等高線",
    "向量場(chǎng)圖", "流場(chǎng)圖", "風(fēng)場(chǎng)圖",  "直方圖", "二維直方圖", 
    "鉆石圖", "信封圖", "箱線圖", "小提琴圖", "餅圖", 
    "自由等高線", "自由填充等高線" ,"自由偽彩圖" ,"三角骨架圖"]

繪圖類(lèi)別跳轉(zhuǎn)坐標(biāo)系

這些繪圖函數(shù)建議使用的坐標(biāo)系如下表

故更改cbTypeChanged函數(shù)如下

def cbTypeChanged(self, evt):
    t = self.drawVars['type'].get()
    p = self.drawVars['proj'].get()
    NO3D = ("曲線圖", "散點(diǎn)圖", "莖葉圖", "條形圖", "誤差線",
        "等高線", "向量場(chǎng)圖", "自由等高線")
    if t in ("圖像"):
        self.wDct['proj']['value'] =  ("None")
    elif t in ("曲面圖", "網(wǎng)格圖", "三角面圖"):
        self.wDct['proj']['value'] =  ("3d")
    elif t in NO3D:
        self.wDct['proj']['value'] =  ("None", "3d", "polar")
    else:
        self.wDct['proj']['value'] =  ("None", "polar")
    
    projs = self.wDct['proj']['value']
    if p not in projs:
        self.drawVars['proj'].set(projs[0])        
    self.cbProjChanged(None)

坐標(biāo)

接下來(lái)要為這些繪圖函數(shù)分類(lèi)，發(fā)現(xiàn)最特殊的是imshow，只支持平面直角坐標(biāo)；然后是三個(gè)三維繪圖函數(shù)，只支持三維直角坐標(biāo)，剩下的基本都同時(shí)支持平面直角和極坐標(biāo)。

def cbTypeChanged(self, evt):
    t = self.drawVars['type'].get()
    p = self.drawVars['proj'].get()
    NO3D = ("曲線圖", "散點(diǎn)圖", "莖葉圖", "條形圖", "誤差線",
        "等高線", "向量場(chǎng)圖", "自由等高線")
    if t in ("圖像"):
        self.wDct['proj']['value'] =  ("None")
    elif t in ("曲面圖", "網(wǎng)格圖", "三角面圖"):
        self.wDct['proj']['value'] =  ("3d")
    elif t in NO3D:
        self.wDct['proj']['value'] =  ("None", "3d", "polar")
    else:
        self.wDct['proj']['value'] =  ("None", "polar")
    
    projs = self.wDct['proj']['value']
    if p not in projs:
        self.drawVars['proj'].set(projs[0])        
    self.cbProjChanged(None)

最后，是坐標(biāo)的變化，直角坐標(biāo)系下的變化為

def cbProjNone(self, t):
    if t in ("點(diǎn)線圖", "曲線圖"):
        self.wDct['dim']['value'] = ('x', 'xy')
    elif t in ("圖像", "直方圖", "餅圖", "箱線圖", "小提琴圖", "信封圖"):
        self.wDct['dim']['value'] = ('x')
    elif t in ("誤差線", "向量場(chǎng)圖", "流場(chǎng)圖", "風(fēng)場(chǎng)圖"):
        self.wDct['dim']['value'] = ('xyuv')
    elif t in ("偽彩圖", "等高線", "填充等高線"):
        self.wDct['dim']['value'] = ('x', 'xyz')
    elif t in ("區(qū)間圖", "橫向區(qū)間圖", "自由等高線", "自由偽彩圖", "自由填充等高線"):
        self.wDct['dim']['value'] = ('xyz')
    else:
        self.wDct['dim']['value'] = ('xy')

經(jīng)過(guò)對(duì)比發(fā)現(xiàn)，極坐標(biāo)情況下除了沒(méi)有imshow之外，其他繪圖函數(shù)的坐標(biāo)軸的個(gè)數(shù)與直角坐標(biāo)基本相同，所以就直接調(diào)用cbProjNone了。

def cbProjPolar(self, t):
    self.cbProjNone(t)

相比之下，三維坐標(biāo)的情況可能更加簡(jiǎn)單一些

def cbProj3d(self, t):
    if t  in ("向量場(chǎng)圖", "誤差線"):
        self.wDct['dim']['value'] = ('xyzuvw')
    elif t in ("曲線圖", "散點(diǎn)圖", "莖葉圖", "階梯圖", "條形圖"):
        self.wDct['dim']['value'] = ('xy', 'xyz')
    else:
        self.wDct['dim']['value'] = ('xyz')

至此，就成功載入了幾乎所有matplotlib中的函數(shù)。
