plot_functions

plot_functions

generate_oms_plot

generate_oms_plot()

Generate OMS plot from uploaded file(s).

Supports three OMS data formats: - .csv: Manual export with headers (standard format) - .dat: Binary live-updating format (46-byte records)

Optionally accepts a .xlsm calibration file alongside the OMS data file. When a .xlsm is present with a .csv, nmol/s conversion and integration are shown. Calibration is not supported for .dat files (no time axis).

reset_species_settings

reset_species_settings(**kwargs)

Clears both num_species and species_names from stored data.

Uses empty list / 0 rather than None because to_web() strips None values (exclude_none=True) and the frontend uses Object.assign which won't delete keys missing from the response.

set_flow_rate

set_flow_rate(flow_rate: str)

Set the carrier gas flow rate used for nmol/s calibration.

Parameters:

Name	Type	Description	Default
flow_rate	str	Flow rate in mL/min as a string. Must be a positive number.	required

set_num_species

set_num_species(num_species: str)

Updates self.data with the user-inputted number of species for .dat file parsing

Parameters:

Name	Type	Description	Default
num_species	str	positive integer as a string representing the number of species (excluding vacuum) in the .dat file	required

set_pressure

set_pressure(pressure: str)

Set the total pressure used for the ideal gas conversion.

Parameters:

Name	Type	Description	Default
pressure	str	Total pressure in Pa as a string. Must be a positive number.	required

set_rate_t_end

set_rate_t_end(rate_t_end: str)

Set the end of the time window for initial rate calculation.

Parameters:

Name	Type	Description	Default
rate_t_end	str	End time in seconds as a string. Must be positive.	required

set_rate_t_start

set_rate_t_start(rate_t_start: str)

Set the start of the time window for initial rate calculation.

Parameters:

Name	Type	Description	Default
rate_t_start	str	Start time in seconds as a string. Must be non-negative.	required

set_species_names

set_species_names(species_names: str)

Updates self.data with user-inputted species names for .dat file parsing.

Parameters:

Name	Type	Description	Default
species_names	str	comma-separated string of species names	required

set_temperature

set_temperature(temperature: str)

Set the temperature used for the ideal gas conversion.

Parameters:

Name	Type	Description	Default
temperature	str	Temperature in Kelvin as a string. Must be a positive number.	required
