Statistics

Development

Only CAN signals can be used with statistics right now, but more types of signals will use the feature in the future!

Different statistics can be used in aggregated results for some types of signals:

• Average
• Max
• Min
• Sum
• Count

All the raw values for a given time span (for example, one second if the report’s granularity is “Second”) are aggregated together using a signal’s selected statistic.

Special Cases

Some statistics can return different values for certain types of signals.

For boolean signals:

• Average: Most frequent value (either true or false).
• Sum: Amount of true values.

For string signals:

• Average: Most frequent string value.
• Max: Alphabetically largest value.
• Min: Alphabetically lowest value.
• Sum: Comma separated aggregation of all string values.
