🤩 [FEATURE] The horizontal axis of the Chart is set to the first point of `swan.log`

🤩 Features description [Please make everyone to understand it]

Like in the chart above, the Y-axis starts at 0 in the bottom left, but the data actually fluctuates between 95 and 100, making it hard to see the changes.

🤔Maybe set the initial Y-axis to the first data point.
