Please fix the bug of heatmap plotting when there is no data #1

Closed Mohitur669 closed 1 year ago

Reproducing the Bug

  1. Run the app.py file through streamlit
  2. Select the "Country-wise Analysis" option
  3. In the "Select a Country" dropdown menu select "Andorra" or maybe "Angola" or maybe "Aruba". In short, the countries which have no data to put into the heatmap give the error mentioned below.

`ValueError: This app has encountered an error. The original error message is redacted to prevent data leaks. Full error details have been recorded in the logs (if you're on Streamlit Cloud, click on 'Manage app' in the lower right of your app).

Please fix the bug as soon as possible.

replacing the below lines:

fig, ax = plt.subplots(figsize=(20, 20)) ax = sns.heatmap(pt, annot=True) st.pyplot(fig)

for case pt is empty or contains null values, we need to try: if pt is None or pt.empty:  st.write("No data available for selected country.") else:   # Heatmap plot   fig, ax = plt.subplots(figsize=(20, 20))   ax = sns.heatmap(pt, annot=True)   st.pyplot(fig)

This will fix the bug.
