tried to download it and still getting:
This histogram is not supported with the current loaded parameters.
If this histogram references Tables, it is possible that the vehicle you are connected to does not support these tables. it is also possible that the sensor required for the Table is not found in the loaded parameters.
and goes on and on...basically, it doesnt work

what are you loading as parameters. you usually use some combo of these depending on histo: dynamic cylinder air, iac position, ltits, stit, idle desired airflow. make sure the dimensions are correct, such as degrees celcius, grams, and so on.

You are missing a PID or sensor in the PID table. Nothing wrong with the histogram - it can't log what you don't give it.
