Mathematica 7에서 ListDensityPlot을 사용하여 (x, y) 위치에 해당하는 일련의 데이터를 플롯하려고합니다. mydata은 데이터 {x, y, f}의 목록입니다. 여기서 f는 -4.5와 + 4.5 사이의 실수입니다.Mathematica의 ListDensityPlot에 대한 ColorFunction과 Blend
ListDensityPlot을 f = -4.5 일 때 진한 파란색으로, f = + 4.5 일 때 진한 빨간색으로, f가 -4.5와 +4.5 사이에 선형으로 보간 할 때마다 파란색과 빨간색으로 보간합니다. 나는 다음과 같은 얻을
Show[{
ListDensityPlot[mydata, FrameLabel -> {"x", "y"},
ColorFunction -> (Blend[{{-4.5, Blue}, {4.5, Red}}, #] &),
ImageSize -> 500],
Graphics[
Map[Text[ToString[Round[#[[4]], 0.1]], #[[1 ;; 2]]] &, data]
]
}]
:
나는 다음과 같은 명령을 사용하려고 한 나는 아래 mydata를 붙여 넣은
. ListDensityPlot은 플롯을 생성하지만, 이상하게도 매우 음수 인 f 영역은 흰색이 아닌 파란색으로 채색되어 있습니다. 이 문제를 해결할 수있는 방법에 대한 아이디어가 있습니까?
