Using plgriddata

Dave Partridge — Tue, 18 Nov 2025 10:31:41 -0000

I have some sparse data (FWHM values) which I am sending into plgriddata, in this case using GRID_NNLI, 1.001f. When I look at the values in the data versus the output grid, I see:

FWHM Min: 1.75532 Max: 7.24468
zg Min: 2.64953 zg Max: 3.795

I've tried various nn.... algorithms, but none appear to preserve the actual minima and maxima. Is that to be expected. I had rather hoped that the actual data points that I do have would be (close to) preserved.

Guidance will be much appreciated.

How to fix this error occurred from wxwidgets binding of PLplot library?

Dingjun Chen — Tue, 05 Sep 2023 20:16:14 -0000

Hi, Dear Sir or Madam,

In my application, I used wxWidgets library and PLplot's wxwidgets binding: wxPLplotwindow.h.
I have successfully built PLplot library but when using PLplot wxwidgets, the following errors occurred. Could someone help me with this problem?
I really need to fix these errors occurred from PLplot's wxwidgets binding and then proceed to build my application.

I look forward to your help.

Thanks and Regards,

Dingjun

Help! I cannot configure PLplot on Windows with CMake3.27.3

Hazen Babcock — Mon, 28 Aug 2023 13:20:53 -0000

Hi, guys,

Could someone tell me how to fix the following errors? I tried to install PLplot library on Windows with CMake 3.27.3. During configuration, there are some head files that cannot be found. I use the GNU c/c++ compilers:
C:\msys64\ucrt64\bin\gcc.exe
C:\msys64\ucrt64\bin\g++.exe
C:/msys64/mingw64/bin/gfortran.exe

What caused such errors? please tell me how to fix these errors.

The following is the CMake log file and you may find details on errors below.

I look forward to your help!

Best regards,

Dingjun

Help for the Installation of PLPLOT in Linux Mint 20.3 Una.

Yihua Liu — Fri, 07 Apr 2023 17:36:40 -0000

As you can see in the ouptut of apt search plplot, you need to run apt install libplplot-dev or sudo apt install libplplot-dev.

Hello everyone

My problem arises with the installation and creation of PLPLOTS, for this I explain my case in a little detail through this publication, requesting the favor of those who can give me any help in the process of installing PlPlot in Ubuntu, I am an average user in Ubuntu and I still have a lot to learn and have just scratched the surface of its potential. I present my case below.

I am currently working on a project that is absorbing ALL my time, I have been reading the documentation posted on the official website https://sourceforge.net/p/plplot/wiki/Building_PLplot/ for its installation for almost a month, I am looking forward to keep trying and install it again as soon and I consider learning PLPLOT because I need it as a premise to install it, I am not really able to understand the process, I have only managed to install cmake, it has been very difficult for me to do the things related to Build Location, Paths proper installation, (Optional) set environment variables to help cmake find system components that are installed in non-standard locations and all that continues from the aforementioned site and I don't know why and how to do this, also read the manual that rests at http://plplot.org/docbook-manual/plplot-5.15.0.pdf section 1.4 page 4 and I still don't understand, for me the manual is a bit concise, and I find it hard to understand what It only talks about examples, and I can't imagine then what are the real routes that such variables have to take.

In contrast to the above, I evaluated the possibility of installing it through apt-get install plplot and the process was not successful either, for which I attach the screenshot shown below.

I thank, immensely in advance, those people who can help me through a detailed guide of such a process to install. At one point I avoided requesting help, on the sites, from what I have read and it seems that the problems that exist are assumed to have already been installed and there is no difficulty installing it, in my case Plplot has caused me difficulty and I was afraid of that .

Being everything for the moment, I thank you for reading this, and I remain attentive to any appreciation in this regard.

Note!! As you can see, English is not my native language, so I apologize if my English is poor and broken.

Best regards

Just to trigger a return, apparently this forum and all the tickets are stale since 2017.
Did all the plplot development go elsewhere ?

I am running plplot V 15.5.0. When I run example x03f.f90 I get the attached plot. The window is huge, comparable to the size of the monitor, and the plot within the window is relatively small. I am using a 32" monitor with 2560x1440 resolution. Is this plot size to be expected?

How to close plplot graphical window/widget with ada code?

oldcodebit — Sat, 20 Mar 2021 11:43:57 -0000

I solved it by reading the following link I found (Closing Window). In ada , the code will be as follows:

  -- Stop waiting for user response
     Set_Pause(False);
    -- Close PLplot library.
      End_PLplot;

To put it back to the way it was before, change False to True.

After running ada code example to plot a function using plplot, the sample code plots the output in graphical window/widget in linux. So one ends up with shell terminal and graphical window. The graphical window can be close with a mouse. How can one close it with ada code line. The ada binding does not have any options for plend() executed by End_PLplot ada code. Is there alternative command in ada to close window/widgets?
