The quote from P.G. Wodehouse's book "Heavy Weather" metaphorically compares the character's emotional ups and downs to a fever chart, suggesting that his experiences are marked by extreme fluctuations of hope and despair. This imagery implies a life filled with dramatic highs and lows, reflecting the intense nature of his aspirations and disappointments.

By likening his emotional state to a fever chart, Wodehouse highlights the unpredictability of the character's journey, emphasizing how his dreams and failures might oscillate wildly over time. This portrayal invites readers to contemplate the nature of ambition and the emotional rollercoaster that often accompanies it.
