SigmaPLot is the easiest. Otherwise, matlab.

Thank you all for your answers. Best regards,

Recently I found an excellent alternative software solution: https://veusz.github.io/

Ugly but cheap: Contour Plots in Excel | How to Create Contour Plots in Excel? (educba.com)

gnuplot seems to be able to do contour plots: http://www.gnuplot.info/. Many open source coding platforms have sophisticated plotting libraries: for example, R has ggplot and Python has matplotlib.

Gnuplot is quite elaborated tool in creating high quality figures if all kinds. Python is very good to. Online, there is plenty examples avaiable for both approaches. Just choose what is more convenient for you.

I used both. Gnuplot can be automatized in the form of shell scripts in Linux. Python can be written in the form of programs.

When you need to produce many figues of the ame kind from different datsla, scripts are the way to go.

Thank you so much fo the additional answers! I'll check out all of your recomendations. Best,

Why not do it in R? https://plotly.com/r/contour-plots/

"Surfer" works well.

Check out freeware Ocean Data View (ODV)

Hello,

Ocean Data View (ODV, https://odv.awi.de/) & Generic Mapping Tools (GMT, https://www.generic-mapping-tools.org/) are classic freeware used by geoscientists.

Hope it can help!

sigmaplot is a good one, or use ArcGIS

Python is very good. you can get the coda in Github.

I have drawn a depth-x-time plot using Goldensoftware Surfer.

Hey, the generic mapping tools package GMT makes one of the best contours on Earth.)

If you know how to code in python, there are several interesting options that might be useful:

Matplotlib package:

https://www.python-graph-gallery.com/85-density-plot-with-matplotlib

Seaborn package:

https://www.python-graph-gallery.com/80-contour-plot-with-seaborn

Hảo ngồi ngay đấy thì ko hỏi?

Probably Python Matplotlib?

https://matplotlib.org/stable/gallery/images_contours_and_fields/contour_demo.html

QGIS

Qgis is so powefull

I think Teckplot360 is a good option.

I guess it depends on what you're generally using.

If you're familiar with MATLAB (https://de.mathworks.com/products/matlab.html) or the free version of it, Octave (https://www.gnu.org/software/octave/download), then a depth-x-time plot as you mention would probably be a Hovmöller diagram. This type of diagram is quite easy to plot as you just have to interpolate the data for your desired spatial and temporal resolution with " 3D meshgrid" and then plot the variables using "contourf".

If you're using python, here is a great example with the entire script available: https://unidata.github.io/python-gallery/examples/Hovmoller_Diagram.html

Otherwise if you just want a 3D Scatter Plot, there are again tutorials for MATLAB (https://de.mathworks.com/help/matlabmobile/ug/creating-3d-scatter-plot.html)

or Python and Matplotlib (https://pythonprogramming.net/matplotlib-3d-scatterplot-tutorial/).

I hope it helps.

All the best,

Naomi
