"""
Creates visualization of thermal reservoir temperature conditions throughout flight.
Parameters
----------
reservoir : Component
Thermal reservoir component containing:
- tag : str
Unique identifier for the reservoir
results : Results
RCAIDE results data structure containing:
- segments[i].conditions.frames.inertial.time[:,0]
Time history for each segment
- segments[i].conditions.energy[coolant_line.tag][reservoir.tag]
Reservoir data containing:
- coolant_temperature[:,0]
Coolant temperature in K
coolant_line : Component
Coolant line component containing:
- tag : str
Unique identifier for the coolant circuit
save_figure : bool, optional
Flag for saving the figure (default: False)
show_legend : bool, optional
Flag to display segment legend (default: True)
save_filename : str, optional
Name of file for saved figure (default: "Reservoir_Conditions")
file_type : str, optional
File extension for saved figure (default: ".png")
width : float, optional
Figure width in inches (default: 11)
height : float, optional

fig : matplotlib.figure.Figure
Handle to the generated figure containing single plot:
Notes
-----
Creates visualization showing:
* Reservoir thermal state
* Temperature evolution
* Time history for each segment
