我有一个3元组的列表,表示3D空间中的一组点.我想绘制一个覆盖所有这些点的表面.mplot3d包中的plot_surface函数需要作为参数X,Y和Z,它们是2d数组.plot_surface是绘制曲面的正确函数吗？如何将数据转换为所需格式？

data = [(x1,y1,z1),(x2,y2,z2),.....,(xn,yn,zn)]

我有一些由外部程序生成的表面数据作为XYZ值.我想使用matplotlib创建以下图形:

• 表面图
• 轮廓图
• 轮廓图与表面图重叠

我已经看了几个用于在matplotlib中绘制曲面和轮廓的示例 - 但是,Z值似乎是X和Y的函数,即Y~f(X,Y).

我假设我将以某种方式需要转换我的Y变量,但我还没有看到任何示例,它显示了如何执行此操作.

所以,我的问题是:给定一组(X,Y,Z)点,如何从该数据生成表面和等高线图？

顺便说一句,为了澄清,我不想创建散点图.虽然我在标题中提到了matplotlib,但我并不反对使用rpy(2),如果这样我可以创建这些图表.

我有很多(289)3d点与xyz坐标看起来像:

用积分简单地绘制三维空间就可以了,但我有表面问题有一些要点:

for i in range(30):
        output.write(str(X[i])+' '+str(Y[i])+' '+str(Z[i])+'\n')

我试图从元组列表中绘制一个三维表面,数据如下:

[(60,5,'121'),(61,5,'103'),(62,5,'14 .8'),(63,5,'48 .5'),(64,5,'57 .5') ,(65,5,'75 .7'),(66,5,'89 .6'),(67,5,'55 .3'),(68,5,'63 .3'),(69,5,'118') ,(70,5,'128'),(71,5,'105'),(72,5,'115'),(73,5,'104'),(74,5,'134') ,(75,5,'123'),(76,5,'66 .3'),(77,5,'132'),(78,5,'145'),(79,5,'115') ,(80,5,'38 .2'),(81,5,'10 .4'),(82,5,'18 .4'),(83,5,'87'),(84,5,'86 .7') ,(85,5,'78 .9'),(86,5,'89 .9'),(87,5,'108'),(88,5,'57 .1'),(89,5,'51 .1') ,(90,5,'69 .1'),(91,5,'59 .8'),(60,6,'48 .9'),(61,6,'33 .3'),(62,6,' - 19.2' ),(63,6,' - 17.5'),(64,6,' - 6.5'),(65,6,'75 .7'),(66,6,'89 .6'),(67,6,' 55.3'),(68,6,'99 .8'),(69,6,'156'),(70,6,'141'),(71,6,'54 .1'),(72,6,' 66.1'),(73,6,'98 .9'),(74,6,'155'),(75,6,'146'),(76,6,'111'),(77,6,' 132'),(78,6,'145'),(79,6,'97 .3'),(80,6,'101'),(81,6,'59 .4'),(82,6,' 70.4'),(83,6,'142'),(84,6,'145'),(85,6,'140'),(86,6,'56 .9'),(87,6,' 77.8'),(88 ,6,'21 .1'),(89,6,'27 .1'),(90,6,'48 .1'),(91,6,'41 .8')]

数据的格式为:(X,Y,Z)

理想情况下,我希望它看起来像这样:

我不确定如何将我的数据提供给matplotlib.
