Hello,

Maybe there is not 3D plots in ParaView:  
[https://discourse.paraview.org/t/plotting-points-on-a-rectangular-grid-with-paraview/3146](http://plotting-points-on-a-rectangular-grid-with-paraview)

Therefore, I tried to use a **Programmable Source** with your data, but it was a bit complicated. (state file is here: [3d\_plot.pvsm](https://discourse.paraview.org/uploads/short-url/f4W8MlHyZxxLReP24IXT9tbaZnv.pvsm) (298.2 KB) )

1. Set the **Output Data Set Type** to **vtkImageData** under the Programmable Source Properties.

2. Declare the extent in **Script (RequestInformation)**.

```python
from paraview import util
util.SetOutputWholeExtent(self, [0, 3000, 0, 50, 0, 0])

```

1. Load the data and assign them to the source output as a field data in **Script**. You need to modify “Path/To/Data/Folder”.

```python
import numpy as np
from io import StringIO

output.SetDimensions(3001,51,1)
output.SetSpacing(1,60,1)

file_name = 'Path/To/Data/Folder/data_1.txt'

# remove \t at the end of sentence
file = open(file_name,'r')
string = file.read()
file.close()
string = string.strip('\t')
string = StringIO(string)

data = np.loadtxt(string)
print(data.shape)

output.PointData.append(data.flatten(), 'data_1')

```

1. Apply the **Warp by Scalar filter**.
