创建计算字段:为了绘制雷达图,你需要创建一些计算字段来表示每个维度的角度和坐标。这通常涉及到使用三角函数(如COS和SIN)来计算X和Y坐标。 例如,你可以创建以下计算字段: tableau // 计算角度角度 = CASE [维度名称] WHEN '维度1' THEN 0 WHEN '维度2' THEN PI()/4 WHEN '维度3' THEN PI()/2 WHEN '...
Now, for us, X = Sin θ and Y = Cos θ. Nice. That’s all well and good, but there’s another step before it’ll actually work in Tableau. We’ve calculated our angle in degrees (because that’s what everybody learns at school first, and that’s still what’s the most intuiti...
