Hi!

I would like to plot 3 data sets with different scales over the same time axis. It would look like the image below that was created with a different software. There use see the time on the x-axis, and 3 different y-axes for my pressure, depth and temperature data.

My data is stored in 3 time series:

ts_p = timeseries(p_hydro, time, 'Name', 'Pressure');
ts_T = timeseries(T, time, 'Name', 'Temperature');
ts_sensorDepth = timeseries(sensorDepth, time, 'Name', 'Sensor Depth');

I tried the function plotyyy that I found on File Exchange http://www.mathworks.com/matlabcentral/fileexchange/1017-plotyyy

plotyyy(ts_p.Time, ts_p.Data, ts_T.Time, ts_T.Data, ts_sensorDepth.Time, ts_sensorDepth.Data, {'kPa', 'degC', 'meters'})

But the properties of the x-axis where not the same as those of a simple time series plot, e.g.

plot(ts_p)

In this case, the x-axis can be formated to show a certain time format, e.g.'mm/dd/yy HH:MM:SS', and when you zoom in, the x-axis adjust itself. I would like to have these features in my plot.

Does anybody have an idea?

ax3 = plotyyy(ts_p.Time, ts_p.Data, ts_T.Time, ts_T.Data, ts_sensorDepth.Time, ts_sensorDepth.Data, {'kPa', 'degC', 'meters'});
for ax = ax3(:).'
  datetickzoom(ax, 'MM/DD/YY');
end
linkaxes(ax3, 'x');

Thanks! That almost did the job, but not quiet. The x-axis is a bit chaotic as you can see in the screenshot. My time data run from June 23. to Dec. 8. and all time vectors are equal, i.e.

ts_p.Time = ts_T.Time = ts_sensorDepth.Time
