Suppose I need to choose all the dates in August, how do I go about doing that? Previously you couldn't set number of samples too high because SerialPlot tried to plot all data at one time. A full date vector has six elements, specifying year, month, day, hour, minute, and second, in that order.

The default StartDate is the lower axis limit converted to the appropriate date number. The type of output is determined by an optional outputType input. Building on windows is a pain. I would like to add a feature request to display the live data in a histogram format, ideally with configurable 'bucket' sizes, but even displaying a tally for each count value received would be really useful.

Because the serial date number format between Excel and Matlab differ, you have to add an offset of 693960 to the retrieved numbers from xlsread. When using datetick , you need an axis that has numbers that are in the range of the dates you need. In the Excel 1900 date system, the Excel serial date number 1 corresponds to January 1, 1900 A. I'm plotting x and y and x is the time. First of all I want to thank everyone who contacted me via various channels for their kind comments! Sorry, qmake project file isn't up to date.

For example, if the minutes element is 70, then datenum adjusts the hours element by 1 and sets the minutes element to 10. When you use datetick by itself, the output appears on the x-axis using a two-digit month and a two-digit day. The following table shows symbolic identifiers that you can use to construct the format.
