Heroku not displaying all the data in bar chart in Python Dash

  heroku, plotly-dash, python

Can anyone let me know why the bar-chart is not populating the entire data in the first tab, whereas when you run it locally you can see values up to 50 on y-axis? (entire GitHub code in link in comments below). Heroku Pipelines link: https://sewerpollutants.herokuapp.com
