A Marker Chart (also called a point chart) displays individual data points on a scatter plot without connecting lines, making it easy to spot clusters and outliers. Learn more in the Bubble Chart documentation, which covers related scatter-based chart types.
This multi-series marker chart plots training data for ten sportsmen with average pulse on the x-axis and average power on the y-axis. Color-coded vertical range markers divide the chart into heart-rate training zones: fat-burning, aerobic, anaerobic, and maximum power. A vertical legend on the right lets you highlight or toggle each athlete to isolate individual performance patterns.
See the Bubble Chart documentation for all configuration options.
