如何用視覺呈現數據
首先,先想想你到底想要呈現什麼?
對比
長條圖很適合用來做簡單的比較,此外,在這個圖內設計者還加上顏色來強調誰領了最多錢
對比: 經過時間
基本上來說,如果數據因為時間而變動的都很適合用線圖
對比: 經過時間
當你想要呈現多組系列時,線圖通常比長條圖好
對比: 經過時間
尤其當你想要呈現多群組時,線圖真的還不賴
對比: 經過時間
設計得好,線圖也可以長得很sexy
小圖對比, 並經過時間
當你想要一次比較很多種東西時, 小圖對比是一個好選擇
位置: Choropleth
好處:
常犯錯誤:
如果地域太小就很難比對
讀者有時候容易誤解
完全忘記要做統計標準化
位置: Proportional circles
好處:
- 精準地展示數據範圍
- 不用做統計標準化,直接用原始數據即可
常犯錯誤:
一般讀者有時候看不懂
完全變成人口數量圖
如果沒有變化的話其實有時候看起來滿無聊的
位置: Proportional circles
好處:
- Showing concentrations
- Emphasizing the data, when data doesn't match existing boundaries
常犯錯誤:
Make sure colors and breaks are meaningful and thought out
Location: Dot maps
Good for:
- Showing density and distribution
- Geography that can not be easily grouped
- Showing single incidents or events
- If exact coordinates are important to your map
Common mistakes:
Overlapped dots
Maps don't have to be maps
Interactions
- If you make the reader click or do anything other than scroll, something spectacular has to happen
- If you make a tooltip or rollover, assume no one will ever see it. If content is important for readers to see, don't hide it
- When deciding whether to make something interactive, remember that getting it to work on all platforms is expensive
Annotations
- If you make the reader click or do anything other than scroll, something spectacular has to happen
- If you make a tooltip or rollover, assume no one will ever see it. If content is important for readers to see, don't hide it
