Since you don't give us the complete list of your data I create one of
my own (everything is converted to InputForm)
lst = ({StringJoin[ToString[#1], "-Mar-86"], Random[Real, {20, 30}]}
& ) /@ Range[30]
{{"1-Mar-86", 23.613774549499446}, {"2-Mar-86", 24.755358595206026},
{"3-Mar-86", 25.78472618921232},
{"4-Mar-86", 24.015010183499367}, {"5-Mar-86", 21.870640478512268},
{"6-Mar-86", 24.84882385269968},
{"7-Mar-86", 26.0558860328317}, {"8-Mar-86", 23.73798568318062}, {"9-
Mar-86", 28.889904184642614},
{"10-Mar-86", 24.489023742622766}, {"11-Mar-86", 27.76230197769936},
{"12-Mar-86", 24.7579400761661},
{"13-Mar-86", 23.288920649503776}, {"14-Mar-86", 25.0449971147684},
{"15-Mar-86", 24.059727034350452},
{"16-Mar-86", 28.55529742653144}, {"17-Mar-86", 20.52248945492899},
{"18-Mar-86", 20.52245213178437},
{"19-Mar-86", 21.453040520574078}, {"20-Mar-86", 22.24958549625941},
{"21-Mar-86", 22.957782039316143},
{"22-Mar-86", 27.344002806162326}, {"23-Mar-86", 26.19686646795488},
{"24-Mar-86", 21.39366477811889},

22.588644210956303}, {"27-Mar-86", 20.41214027874256},
{"28-Mar-86", 27.378654594619523}, {"29-Mar-86",
27.473367011304425}, {"30-Mar-86", 27.739820358256623}}
Now amog other things you can try
ListPlot[Transpose[lstdays][[2]], PlotStyle -> PointSize[0.02], Frame -
> {True, True, False, False}, Axes -> False,
PlotLabel -> "March 1986", ImageSize -> 500, TextStyle -> {FontSize
-> 14}, FrameLabel -> {"day", "value"}];
(*plot to be displayed*)
Contact again to this forum for modify the "look" of the graph for
your specific needs!
