What Is the Rating Comparison Chart?
The Rating Comparison Chart lets you select multiple horses from a racecard and overlay their RaceMetrics Rating histories on a single chart. It is a quick way to see which horses are improving, which are declining, and how they compare over their recent careers.
How to Use It
Open any racecard in the Ratings view. You will see checkboxes in the first column next to each runner. Tick the horses you want to compare — up to 6 at a time. The comparison chart panel appears below the ratings table.
Reading the Chart
Each horse is plotted as a line with a distinct colour. The x-axis shows race numbers (most recent on the right). The y-axis shows the RaceMetrics Rating. Hover over any data point to see the exact rating, date, and rating change for that race.
The interactive legend at the top lets you toggle individual horses on and off. Click a horse's name in the legend to hide or show their line.
Adjusting the Range
Use the race limit buttons to control how many races are shown: 10, 20, 50, or All. A shorter range focuses on recent form; a longer range shows the broader trajectory.
Highlighting a Horse
Click on any line or data point in the chart to highlight that horse. The other lines fade, making it easier to focus on one horse's trajectory. Click again to remove the highlight.
Practical Use
Before a competitive handicap, select the market leaders and compare their rating curves. A horse whose rating has climbed steadily over 10 races is on a different trajectory to one whose rating has plateaued. This visual comparison can reveal form trends that raw numbers alone might obscure.
Selections are cleared when you navigate to a different race, so each race starts fresh.
