What is the highest and lowest points of a line graph?

The highest point of a line graph, often referred to as the peak or maximum, represents the greatest value or data point within the plotted range. Conversely, the lowest point, known as the trough or minimum, indicates the smallest value on the graph. These points help visualize trends and fluctuations in the data over time or across categories. Analyzing these extremes can provide insights into performance, growth, or decline in the represented dataset.
