how to plot four different variables sharing same axis but with different x and y axis limits

6 visualizaciones (últimos 30 días)
i have saved four variables from a GUI, it consised of four signals with respect to time, now i have four variables having different data of signals with respect to their capture time. i want to plot these variables in single plot sharing same x and y axis but with thier own limits lets say
s1 was captures from 0.5 to 1 hours, and s2 from 5-5.5hours now i want to plot them all togeter but first s1 should start in pplot and secondaly s2, in that case the xa axis would be from 0to6 hours, how to do that?
variable are capured from figure 1 grapgh, using brush tool in matlab 2019 are saved s1 s2 s3 and s4, here in this code i have not mentioned about those variables, to run this code you can take my data text file that should be imported to workspace using clumn vector style when impoting. thanks

You can refer the following code snippet which sets and uses multi-row tick labels to resolve your problem.
