When setting up a Statistics Collector you specify the data type and format for each column. "Object" would be used when you use the expression "StatisticsCollector.getID()" to generate a unique ID for an object. Date/Time interprets the number as a datetime value (seconds since 01.01.1601) and would typically be used for the x-axis of a time plot.
Thank you for your response.
However, I didn't express my question clearly.
I wanted to ask how to display numbers as percentages in the Global Table.
Apart from converting the number to a string and writing that to the global table, this is not possible as far as I know. A global table only displays the raw values.
double num;
string percentString = string.fromNum(num*100, 2) + "%";
