Answer 1

The error TypeError: this.Plotly.newPlot is not a function typically occurs when the Plotly library is not properly loaded or initialized, especially when using custom or external graphing code like the graphing module in your example.

1. Check Plotly Installation

Ensure that Plotly is installed and imported properly in your environment. You can install it using:

pip install plotly

Then, ensure you import it in your script:

import plotly

2. Check Custom Graphing Code

Since the error is likely related to custom graphing code, verify that the graphing module is properly implemented and the Plotly API is used correctly within it.

You can try testing Plotly directly outside of the custom graphing module to see if Plotly is working properly in your environment. For example:

import plotly.express as px

import pandas as pd

# Create a simple DataFrame

df = pd.DataFrame({

    "x": [1, 2, 3, 4, 5],

    "y": [10, 11, 12, 13, 14]

})

# Generate a simple scatter plot

fig = px.scatter(df, x="x", y="y")

fig.show()

If the Plotly plot works directly, the issue might be in the graphing module.

3. Debug the Graphing Module

Check the graphing module code for how Plotly is being used. Ensure that the correct Plotly objects and functions are called. If the graphing module was downloaded from a GitHub repository, ensure it is compatible with your version of Plotly.

4. Update Plotly

Sometimes using an outdated version of Plotly can lead to such errors. Update Plotly to the latest version:

pip install --upgrade plotly

If you cannot fix the custom graphing module, you might bypass it and directly use Plotly’s built-in functions (like plotly.express or plotly.graph_objs) for your visualizations.

If these steps don't resolve your issue, let me know if you need further assistance debugging the graphing module.
