Framed plot provides an extra vertical line

Sometimes I have observed the Plot command produces a plot with an extra vertical line. An examples of what I mean is in the first graph below, which is a framed plot with specified ticks and grid lines for the x-axis. Note the extra vertical line running the height of the plot at x = 50. It is interesting to note that this vertical line is at the same location that Plot would automatically place the y-axis, as shown by the second plot, which is an unframed plot with default settings. Note that in this case, the frame ticks and grid spacing was chosen to correspond to a 24 hour cycle, i.e. one tick for each day and a 6 hour grid spacing. There is probably some command that I should add to the first plot to suppress this extra vertical line. Can someone point out what that command is? Thanks, Bob. tTicks = Range[0, 24 30, 24]; tGrid = Range[0, 24 30, 6]; Plot[ { Sin[t]}, {t, 24, 24 10 } , PlotRange -> {{24, 24 10}, {-3, 3} } , Frame -> True , FrameTicks -> {tTicks, Automatic} , GridLines -> {tGrid, Automatic} ] Plot[ { Sin[t]}, {t, 24, 24 10 } , PlotRange -> {{24, 24 10}, {-3, 3} } ]
