[docs]def altplot(kp, parameter=None, time=None, errors=None, sameplot=True, list=False, title='Altitude Plot', ylog=False, qt=True): ''' Plot the provided data plotted against spacecraft altitude. If time is not provided plot entire data set. Parameters: kp : dict insitu kp data structure/dictionary read from file(s) parameter : list of str/int The parameter(s) to be plotted. Can be provided as integers (by index) or strings (by name: inst.obs). If a single parameter is provided, it must be an int or str. If several are provided it must be a list. A list may contain a mixture of data types. time : list of str Two-element list of strings or integers indicating the range of Time to be plotted. At present, there are no checks on whether provided Times are within provided data sameplot : bool if True, put all curves on same axes if False, generate new axes for each plot list : bool Lists all Key Parameters instead of plotting title : str The Title to give the plot ylog : bool Displays the log of the y axis qt : bool If true, plots with qt. Else creates an HTML page with bokeh.
