How is your data formatted ? It only contains numbers.

Hello,
I was able to load it in the same way as the link below.

> One way to achieve this is to use a Programmable Source. Source \> Alphabetical \> Programmable Source Fill in the Script (RequestInformation) as shown below. from paraview import util util.SetOutputWholeExtent(self, [0, 98, 0, 37, 0, 0]) Here, the values to be specified for SetOutputWholeExtent are obtained by counting the number of rows and columns from the csv file in advance. Enter the following in Script. import numpy as np path = 'data\_path/Sample.csv' a = np.loadtxt(path, delimiter=…
Now you need to modify the `Script (RequestInformation)` and `Script` in the **Programmable Source** Filter.
- `Script (RequestInformation)`
```python
from paraview import util
util.SetOutputWholeExtent(self, [0, 140, 0, 141, 0, 0])
```
- `Script`
```python
import numpy as np
path = 'your_data_path/Ux.txt'
a = np.loadtxt(path, encoding='utf-8_sig').flatten()
output.SetDimensions(141, 142, 1)
output.SetOrigin(0.0, 0.0, 0.0)
output.SetSpacing(1, 1, 1)
output.PointData.append(a, 'height')
```
