How to Create Boxplots with Aplot or Cplot2

This tutorial uses data from the 19 September 2017 flight found on ADTAE.

Step 1: Gather Information

Need to know the start time, stop time, x- and y-parameter numbers in the input file. The parameter numbers can be found using 'listparas' command.

Listparas example:

 listparas 17_09_19_20_24_36.basic.1Hz

Listparas example output:

 1) Air_Temp
 2) MachNo_N
 3) IAS
 4) AIMMS_TAS
 5) Press_Alt
 6) Pot_Temp_T1
 7) IAS_A
 8) CIP_TAS
 9) Density
10) TCritWing
11) TCritIcing

Step 2: Generate the statistics file.

Aplot

This feature is still currently under development in Aplot.

Cplot2

For each time period use the following command to generate the mean, standard deviation, 5-, 25- 50-, 75- and 90-percentiles, number of samples in the time period, minimum, and maximum statistics:

 cplot2 outputstats time_min = start_time time_max = stop_time y_para = y_parameter_number stats_file = output_statistics_file_name input_file_name

Example:

 cplot2 outputstats time_min = 74248 time_max = 74669 y_para = 4 stats_file = 17_09_19_20_24_36.basic.aimms_TAS.stats  17_09_19_20_24_36.basic.1Hz
 cplot2 outputstats time_min = 74963 time_max = 75160 y_para = 4 stats_file = 17_09_19_20_24_36.basic.aimms_TAS.stats  17_09_19_20_24_36.basic.1Hz
 cplot2 outputstats time_min = 75469 time_max = 75880 y_para = 4 stats_file = 17_09_19_20_24_36.basic.aimms_TAS.stats  17_09_19_20_24_36.basic.1Hz
 cplot2 outputstats time_min = 75967 time_max = 76345 y_para = 4 stats_file = 17_09_19_20_24_36.basic.aimms_TAS.stats  17_09_19_20_24_36.basic.1Hz
 cplot2 outputstats time_min = 76462 time_max = 76948 y_para = 4 stats_file = 17_09_19_20_24_36.basic.aimms_TAS.stats  17_09_19_20_24_36.basic.1Hz
