用 Bokeh 表示調(diào)查結(jié)果

• 安裝時(shí)要有 API 秘鑰，還要注冊(cè)，不是只用 pip 安裝就可以；

• Plotly 所繪制的數(shù)據(jù)和布局對(duì)象是獨(dú)一無(wú)二的，但并不直觀；

• 圖片布局對(duì)我來(lái)說(shuō)沒(méi)有用（40 行代碼毫無(wú)意義！）

• 你可以在 Plotly 網(wǎng)站和 Python 環(huán)境中編輯圖片；

• 支持交互式圖片和商業(yè)報(bào)表；

• Plotly 與 Mapbox 合作，可以自定義地圖；

• 很有潛力繪制優(yōu)秀圖形。

• 實(shí)例化圖片；

• 用圖片目標(biāo)屬性格式化；

• 用 figure.add() 將數(shù)據(jù)添加到圖片中。
