To create a histogram using the default Pandashist()method, we first need to create a Pandas DataFrame from a Python dictionary. # Create DataFrameimportpandasaspdimportnumpyasnp df=pd.DataFrame({'Maths':[80.4,50.6,70.4,50.2,80.9],'Physics':[70.4,50.4,60.4,90.1,90.1],'Chemistry':[40,60.5...
In Pandas, you can save a DataFrame to a CSV file using the df.to_csv('your_file_name.csv', index=False) method, where df is your DataFrame and index=False prevents an index column from being added.
Lastly, let’s change the color of the bins to orange to make the visualization stand out a little. # Create histogram fig = go.Figure(data = [ go.Histogram( x = olympic_data.age, xbins=go.histogram.XBins(size=5), # Change the bin size marker=go.histogram.Marker(color="orange")...
