基於這問題 我能夠將部分數值和總值放在我的長條圖上。我的長條圖有一些非常小的值,並且不可能將這些數字容納在某些範圍內。我想把這些標籤移到一邊。我能怎麼做?
請注意,在一種情況下,我有兩個連續的小範圍,因此將這些值放在交替的兩側會很棒。
先致謝!
這是我到目前為止所擁有的:
以及相關代碼:

答案1
因此,從文件中解決這個問題有點棘手,nodes near coords align
並且visualization depends on
應該是靈丹妙藥。奇怪的是它失敗了。
相反,我們必須結合visualization depends on
使用every node near coord/.append style
作為一種解決方法。
也必須內聯包含其數據,如所解釋的@符號1,以防止錯誤。
Package PGF Math Error: Unknown function `thisrow_unavailable_load_table_directly' (in 'thisrow_unavailable_load_table_directly')
我還必須將數據重組為表格形式。我想人們可以使用帶有原始座標資料的元標記,但我還沒有嘗試過。
