# This holds the structure of a single data point of a StatisticDataType.

# This message is used in MetricsStatisticsMessage, defined in MetricsStatisticsMessage.msg.

# Examples of the value of data point are

# - average size of messages received

# - standard deviation of the period of messages published

# - maximum age of messages published

# A value of nan represents no data is available.

# One example is that standard deviation is only available when there are two or more data points but there is only one,

# and in this case the value would be nan.

# +inf and -inf are not allowed.

# The statistic type of this data point, defined in StatisticDataType.msg

# Default value should be StatisticDataType.STATISTICS_DATA_TYPE_UNINITIALIZED (0).
