Plotting data with microsecond accuracy

I am trying to plot voltage values that have been sampled at 50 us intervals. Each of these samples have been timestamped so that they can be compared with other measurements. I've converted the timestamps to datenum values but when I use the PLOT function, the x-axis is scaled in such a way that all of my data is compressed to the centre of the plot. I have tried manipulating the axis using xlim and datetick but nothing changes. What I really need to be able to is zoom in on specific areas of the plot while safegaurding the timestamps and scaling the axis accordingly. Any advice would be much appreciated.

Best regards,

Kevin
