MATLAB 2008 PLOT WITH SECONDARY AXIS CODE

Have a look at the different datestr format if you want to modify the output format. No need to use datetick any more since we set the tick string ( XTickLabel) on the same line where we force their positions (by setting XTick).

MATLAB 2008 PLOT WITH SECONDARY AXIS CODE

If you go this way, forget the last 2 lines of code in the solution above. This code makes the secondary axis but the avri will not plot to it- it still plots to the wrong axis. I have four lines to plot: three should be on the bottom x axis and the fourth (avri) should be on the top x axis. MATLAB has many commands that can be used for creating different types of plots. I am having a similar probelm but this code does to work for me. This is tr ue in any field, but especially in science and engineering where MATLAB is mostly used. You can change the year step to 1 or anything that look good for your figure. Plots Plots are a very useful tool for presenting in formation. Set(gca, 'XTick', tickDates, 'XTickLabel', datestr(tickDates,'yyyy') ) %// set the position and label of each tick TickDates = datenum( 1996:tickStep:2008 ,1,1) %// creates a vector of tick positions tickStep = 2 %// choose the number of years you want To do that, we'll define a vector of dates, spaced according to your liking, then tell matlab to draw ticks only at these locations. If you want to override this behavior and control the exact spacing or positions of the ticks, you have to tell Matlab where to place them. By default, Matlab spaces the ticks marks, grid lines and labels automatically, trying not to overload the figure by adding a tick at every data point. To complete the answer, based on comment. Tips: Use the datetick instruction after the plots (the plot command may reset your tick otherwise)ДЄs written, this will only show the year, but since you imported your original date/time value, you can also choose a different dateFormat which would also display the month and year. Then at the time of display, use: %% // display the results Then run your calculations code ( not repeated here, just the same code you wrote). Time = datenum( data %// isolate your variableДЄfter that, you have the same variable in C that you got with importdata, but you also have your original time vector (the same length) in the variable time So looking at the code you detail in your previous question, import your data by doing: %% // Import your data (textscan gives you more control)ДЇid = fopen( '2.txt', 'r') %// open your fileДata = textscan(fid,'%s %f') %// import the content To do that, you can use textscan (instead of importdata), it gives you more control. So you get a time vector the same length than your data. The best thing to do is to import your date vector properly in the first place.
