Hints for Exercise 14¶
General hints¶
Plotting predicted ages as horizontal lines¶
I suggest that you add horizontal lines to your plots of the thermochronometer data to show the predicted ages you calculate.
If you have read in the data file with the values for latitude stored in a variable latitude, you can plot a predicted age predictedAge as a black horizontal line as follows:
plt.plot([min(latitude), max(latitude)], [predictedAge, predictedAge], 'k-')
plt.show()
This will create a horizontal line from the minimum latitude to the maximum latitude with a vertical value of predictedAge.
The “trick” here is to put Python lists into the plt.plot() command instead of list or array variables.
Lists are values separated by commas within square brackets ([ ]), and here we just give 2 values in each list for the x and y points that define the ends of the line.
