    #Print a title block for the page.
    report.Title()
 
    #Our AQL query goes here
    query = "('[ASSET]') ASSET ('[PROPERTY]') PROPERTY VALUES"
 
    #Get the pandas data-frame with the results.
    df = report.GetHistory(query)
 
    for k in df.columns:
        ax.plot(df[k],label=k)     
 
    #Clean up and prettify
    ax.margins(x=0)
    ax.set_xlabel("Time")
