Encoding time by color

The screen only has two dimensions, but we can encode another dimension in the scatter plot using color. Here, we will visualize the climate_change dataset, plotting a scatter plot of the "co2" column, on the x-axis, against the "relative_temp" column, on the y-axis. We will encode time using the color dimension, with earlier times appearing as darker shades of blue and later times appearing as brighter shades of yellow.

Instructions

100 XP
  • Using the ax.scatter method add a scatter plot of the "co2" column (x-axis) against the "relative_temp" column.
  • Use the c key-word argument to pass in the index of the DataFrame as input to color each point according to its date.
  • Set the x-axis label to "CO2 (ppm)" and the y-axis label to "Relative temperature (C)".
