### Error plotting heatmap: ‘x’ is a list, but does not have components ‘x’ and ‘y’

This error message typically occurs when you are trying to create a heatmap using a list instead of a 2D array or a dataframe.

A heatmap requires a 2D array or a dataframe where each row represents a point on the x-axis and each column represents a point on the y-axis. The values in the array or dataframe represent the magnitude of the data at that particular point.

If you are trying to create a heatmap using a list, you will need to convert it to a 2D array or a dataframe before plotting. Here are some examples of how to do this:

1. Convert a list of lists to a 2D array:
```lua```import numpy as np

data = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
data_array = np.array(data)
``````
1. Convert a list of dictionaries to a dataframe:
```kotlin```import pandas as pd

data = [{'x': 1, 'y': 2, 'value': 3},
{'x': 4, 'y': 5, 'value': 6},
{'x': 7, 'y': 8, 'value': 9}]
data_df = pd.DataFrame(data)
``````

Once you have converted your data to a 2D array or dataframe, you should be able to create a heatmap without encountering this error.
