Contour Plot in Matlab: DATA COLLECTED vs TIME in date and hours

Click For Summary
SUMMARY

The forum discussion focuses on creating a contour plot in MATLAB using time series data collected on September 23, 2008. The user seeks guidance on converting date and time into a time series vector for plotting. Key resources provided include MATLAB tutorials and data import methods from ASCII text files. The discussion concludes that a contour plot may not be suitable with only one variable (data vs. time), suggesting alternative plotting options like bar charts.

PREREQUISITES
  • Familiarity with MATLAB 2023a for data visualization
  • Understanding of time series data formatting in MATLAB
  • Knowledge of importing data into MATLAB from ASCII text files
  • Basic concepts of 2D plotting and contour plotting in MATLAB
NEXT STEPS
  • Explore MATLAB tutorials on data visualization at Mathworks
  • Learn about importing data using MATLAB's data import GUI
  • Research the differences between contour plots and bar charts in MATLAB
  • Study how to format date and time for time series analysis in MATLAB
USEFUL FOR

This discussion is beneficial for MATLAB users, data analysts, and students who are new to data visualization and need guidance on plotting time series data effectively.

Hello, All. Thank you in advance for any help, contribution and your time. I have been asked to do a contour plot with a data vs time (date and hours), I am new with Matlab and I don't really know how to make this date and hour in a time series vector to do my contour plot. I have added the data and time for the plot, each time correspond to each data.

DATA & TIME: 09/23/2008 06:37:00 09/23/2008 06:46:00 09/23/2008 06:52:00 09/23/2008 07:00:00 09/23/2008 07:03:00 09/23/2008 07:10:00 09/23/2008 07:15:00 09/23/2008 07:15:00 09/23/2008 07:15:00 09/23/2008 07:22:00 09/23/2008 07:26:00 09/23/2008 07:30:00 09/23/2008 07:44:00 09/23/2008 07:48:00 09/23/2008 07:52:00 09/23/2008 07:52:00 09/23/2008 08:00:00 09/23/2008 08:07:00 09/23/2008 08:26:00 09/23/2008 08:26:00 09/23/2008 08:26:00 09/23/2008 08:26:00 09/23/2008 08:36:00 09/23/2008 08:45:00 09/23/2008 08:45:00 09/23/2008 09:03:00 09/23/2008 09:07:00 09/23/2008 09:10:00 09/23/2008 09:12:00 09/23/2008 09:45:00 09/23/2008 09:53:00 09/23/2008 09:56:00 09/23/2008 09:59:00 09/23/2008 10:15:00 09/23/2008 10:19:00 09/23/2008 10:23:00 09/23/2008 10:26:00 09/23/2008 10:46:00 09/23/2008 10:51:00 09/23/2008 11:03:00 09/23/2008 11:09:00 09/23/2008 11:30:00

Welcome to PhysicsForums!

We can't do your (home)work for you, but we can help you along a little. If you're absolutely brand new, I suggest making use of the Mathworks' MATLAB tutorial, or their getting started with MATLAB series:
http://www.mathworks.com/academia/student_center/tutorials/launchpad.html (Tutorials)
http://www.mathworks.com/help/techdoc/learn_matlab/bqr_2pl.html (Getting Started)

If you have these in an ASCII text file (tip: copy and paste into Notepad / another text editor, with or without the column heading, save, and then use the MATLAB data import GUI), you can easily import them into MATLAB:
http://www.mathworks.com/help/techdoc/import_export/f5-35378.html

Since you only have 'data' and 'time / date', I don't really think you can make a contour chart (usually implies you have two variables, along with some data). Nevertheless, you can read more on plotting at the Mathworks:
http://www.mathworks.com/help/techdoc/ref/plot.html (2D Plotting)
http://www.mathworks.com/help/techdoc/creating_plots/f10-2524.html (Contour Plotting)

EDIT: If you want a bar chart, you can also make that in MATLAB. For the basics of that:
