行末のラベルが重ならないようにすることは、このデータにとって特別な課題です。なぜなら、同じコードをかなり異なるデータで動作させたいからです。以下の例では、一部のラベルは、スペースを確保するために、ラベルを付けているポイントから遠く離れている必要があります。それを適用する必要がある各データセットのコードをカスタマイズできないため、プログラムでそれを行う方法があるかどうかを知りたいだけです。ありがとう！
ラベルの書式設定にも苦労しています。最も近いパーセントに丸めましたが、遊んでいる sprintfにもかかわらず、小数点と末尾のゼロを取り除く方法がわかりません。
私のデータはこれで再作成できます：
