Color by Column

[JorgeMiguelGomes]

WHAT THE CODE DOES SO FAR

This code will return a plotly graph with a dropdown menu where you can choose different COVID-19 related data (New Cases Total, New Cases Daily, etc)

PROBLEM

Using the dropdown menu returns the correct values but assigns the same color to all of them (blue)

NOT WORKING SOLUTION

Create a dictionary for every column (here just for the first two) and assign a specific color to each

# assign colors to column  using a dictionary
colors = dict('casos_novos_t':'coral',
          'casos_novos_d':'darkviolet')

Use marker_color to force the use of a specific color

However marker_color = colors returns an error

INSIGHT

Without a dropdown menu plotly generates one color for each column, automatically.
