Aggregated Charts
Aggregated charts are an addition available in the telemetry viewer since version 4.5. Rather than direct comparison between two laps, the aim of these charts is for the player to better understand the behavior of characteristics of the car/setup, thus aiding in setup improvement.
Aggregated chart can be opened using the icon below the lap selector. This will open the aggregated chart selection, if at least one lap is loaded, and no laps are currently loading. The selected aggregated is opened in a new window and takes all data points of all selected laps. Unlimited number of charts can be opened at a single time.
Below is the list of aggregated chart, with a short description currently present in the application. Some charts have a filter for data points, and only those who match this filter are shown on the chart (i.e. throttle > 95%).
Histograms show the timed percentage distribution of measured values. In other words, it shows how often, from all measurement, was the value in the band represented by the bar. Important property of histogram chart is the band size, which determines how big the value range of each bar is. Each histogram has a default band size value, but this can be changed on the chart itself. It is possible to select and deselect individual bands using shift + left mouse button. Datapoints contributing to selected bands will shown on the track map. I might be preferable to turn off sector coloring for better readability.
- Filter: Brake < 1%, Clutch < 1%
- Description: RPM Histogram shows % of time spent in each RPM band. It shows one chart for all gears and then separate, smaller chart, for each gear. This chart is useful to see if you're spending the majority of time in the useful RPM range, and to see how much time you don't.
- Filter: None

Description: Suspension Velocity Histogram shows the % of time the suspension is moving at a speed represented by the band. This is useful for damper fine-tuning. Each wheel has it's own chart. There are few basic properties to look at this chart.
- Height of 0 band: Looking at the 0 band, on each of the 4 charts, tells us about the relative stiffness of suspension on each wheel. Considering the spring stiffness is the same, a higher 0 band means that the dampers are stiffer. Equally, a lower band means that the dampers are softer.
- Histogram Symmetry: In most cases you're aiming for a symmetric histogram, centered at 0, because that means that bump and rebound dissipate equal amount of energy. If the suspension spends more time in bump region, then softening the bumps or stiffening the rebounds should make the chart more symmetric. The the same logic applies to the rebound area, if the chart is skewed in that direction, then softening the rebound or stiffening the bump should make the chart more symmetric. In downforce cars rebound damping can be used to influence the attitude of the car, in such cases the chart will most likely not be symmetrical.
- Filter: None
- Description: Ride height histogram shows the % of time each corner of car spent at given height. This can be useful to check if the car isn't bottoming out, or coming close to bottoming, or if it isn't sitting unnecessary high for the majority of time. It can be also used to check if the ride height is uniform between right and left side of the car.
Scatter plot is a basic chart, which shows the relationship between two measured quantities (i.e relationship between speed and rpm). Each measurement is shown as a single point on the chart. Each chart can have multiple point series in it (i.e. one separate for each gear, or one for each wheel.)
- Filter: Throttle > 95%, Brake < 1%, Clutch < 1%
- Description: This chart show the Horizontal Acceleration (forward/backward momentum), in relationship to speed. This shows how fast the car is able accelerate, at given speed, and gear. For this reason only data points where the player is applying full throttle are taken. Each gear has its own series and also separate chart. This chart can help with finding the ideal shift points. Ideal place to shift is when the horizontal acceleration, of the next gear, at the same speed, is higher (or at least the same), as the current gear.
- Filter: Throttle > 95%, Brake < 1%, Clutch < 1%
- Description: This chart shows the Horizontal Acceleration (forward/backward momentum), in relationship to RPM. This shows how fast the car is able accelerate, at given RPM, and gear. For this reason only data points where the player is applying full throttle are taken. Each gear has its own series and also separate chart. This chart can help with determining the rpm ranges the engine produces the most power. This is more useful in older cars, which usually don't have as flat power curve, as the new cars.
- Filter: Brake < 1%, Clutch < 1%
- Description: This chart show the RPM, in relationship to speed. This chart can help with gearing set-up, as it shows at what rpm the car will be at given speed.
- Filter: Horizontal acceleration < +-0.1G
- Description: This chart helps to visualize body roll of chassis in relation to Lateral Acceleration (turning). Only data points with little to no horizontal acceleration are displayed to limit the effect acceleration/breaking has on ride height.
- Filter: Lateral acceleration < +-0.1G
- Description: This chart helps to visualize body roll of chassis in relation to Horizontal Acceleration (acceleration and braking). Only data points with little to no lateral acceleration are displayed to limit the effect turning has on ride height. This chart is more useful for non-downforce cars, as in those this view is skewed by the effect downforce has on the car. For this reason the region around 0g horizontal acceleration shows the lowest ride height, as this is the region where the car will be traveling closest to its top speed.
- Filter: None
- Description: This chart helps to visualize change of ride height in relationship to speed. This chart is useful mostly for downforce cars, as it shows how much the change in speed (downforce) affects the ride height. It can be used to see if there is significant change of rake in higher speed, or if the downforce inducted change causes the car to bottom up.
- Filter: None
- Description: This chart shows the relationship between car speed and downforce. This can be useful to see how changes to the car wing and attitude affected the total downforce available. In ground effect reliant cars loss of downforce caused by the car bottoming out can also be seen on this chart. Only R3E currently provides downforce information.
