Python 过焊时，mayavi未对齐流线和图像平面

我有3D标量和矢量数据，我正在与流线（

mlab.pipeline.streamline

）和图像平面（

mlab.pipeline.image\u plane\u widget

）一起绘制。这通常是可行的，但偶尔（即在某些数据集上）两种类型的图形会出现不对齐，即使数据形状完全相同

好例子：

坏例子：

这始终是一个范例：流线的边界框沿一个轴延伸。。。没有设置正在更改

例如，我有一个标量字段

scal

，其维度与向量字段

vect

相同：

mlab.options.offscreen = True

可在此处找到包含重现问题的数据的代码：

问题在于

图像平面小部件

根本不接受“范围”参数。从

image\u plane\u widget

和

streamline

中删除“extent”参数可以使对象匹配。

你能给出一个完整的工作示例吗？@SAAD我刚刚发布了数据和代码来重现错误
