Certainly! Below is a Python script that uses the `matplotlib` library to plot the data from the provided text files. The script accepts multiple filenames as command-line arguments and plots the data from each file on the same graph:

```python
import matplotlib.pyplot as plt
import sys

def read_data_from_file(filename):
    xs = []
    ys = []
    
    with open(filename, 'r') as file:
        for line in file:
            # Splitting the line by space to get x and y values
            x, y = map(float, line.split())
            xs.append(x)
            ys.append(y)
    
    return xs, ys

def main():
    if len(sys.argv) < 2:
        print("Usage: plotter.py file1 [file2 ...]")
        sys.exit(1)

    # Initialize plot
    plt.figure(figsize=(10, 6))

    # Read and plot data for each file
    for filename in sys.argv[1:]:
        xs, ys = read_data_from_file(filename)
        plt.plot(xs, ys, label=filename)

    # Customize the plot
    plt.title("Data Points from Files")
    plt.xlabel("X")
    plt.ylabel("Y")
    plt.legend()
    plt.grid(True)

    # Display the plot
    plt.show()

if __name__ == "__main__":
    main()
```

To use this script:

1. Ensure you have `matplotlib` installed. If not, install it using:
```
pip install matplotlib
```

2. Save the above script to a file, say `plotter.py`.

3. Run the script using the command line, passing file names as arguments:
```
python plotter.py data1.txt data2.txt ...
```

This will display a graph with the data points from the provided text files. Each file's data will be plotted with a different color, and the legend will show the filenames for clarity.
