I discovered and downloaded Veusz today, and started to use it with several tutorials. After importing my data from a .csv file (that I correctly preview in the 'Import window'), I try to select the data I want to appear along the x and y axis; when I click on the arrow near 'X data' and 'Y data', nothing appears and I cannot choose anything to appear on my xy graph.
I tried several times to close and open the software, nothing changes. Here is a picture of my window:
I got the answer - which is in fact really simple. I just had to select the English style for the numerics (I'm actually on a French computer). It went well after that.

Under Atom 1.23.3 x64, I can see some visual parasites (see picture below), like vertical blue lines. It happens whatever the file format (.py, .tex, .txt...).
I'm under linux Debian Buster/Sid.
Edit : this "thing" apparition seems to be randomness and purely visual, i.e., it's impossible to select and inspect it. It lies in between two caracters. It will move if I zoom in or out, but always be somewhere, as noise.
I was wondering if there is a way to save surface plots in IDL in a way that is convenient to reopen them. As far as I am aware there are only two ways of doing this:
The first way is to save your surface plot as an image e.g. png. The trouble with this is that the viewing angle is fixed and you can no longer drag with the mouse to rotate the surface plot.
The second way is to save the code which generates the plot. Trouble with this is the code often generates loads of plots which are usually just saved as images.
I would like something you can open easily and which opens the surface plot as though you had just run the code to generate it. So that you are free to rotate it by dragging the mouse.
Does this exist?
I only have IDL version 8.3.
If you 'Generate code/save data' (either via the toolbar at the bottom of the window or via the generateCode method with the SAVEDATA keyword), you get a .sav file that contains your plot. Either use the code generated to restore it, or use the generated code as an example to write your own.

Plotting UK postcodes on a map in R
I am trying to plot various postcodes on a map using the plotGoogleMaps function, however when I get to the last step e.g.
m <- plotGoogleMaps(UK_Map , filename='MAP_UK.html')
Nothing happens except for the little stop sign in the corner appearing as if something is loading.
Is anyone able to tell me how I can view the map / where I'm going wrong? I have read elsewhere that you can supposedly view the file in your working directory but unfortunately it's not there so I'm not sure what to do.
I just downloaded Octave today and I have used a little bit of Matlab. I am working on a machine learning problem and one of the things I wanted to do was opening a JPEG file in Octave as a matrix.
I = imread('nameOfTheFile.JPEG');
imshow(I)
This opens a figure with the image I was looking at. I clicked on the image out of habit and the figure closed along with Octave. I'm not sure why and it seems very inconvenient. Can anyone help me?
Thanks!
Concerning the superb iplots package in R:
By default, pressing CTRL and moving the mouse over a point in a scatter plot shows the x and y values of this point. How can I extend this to also show other attributes, which are not part of the plot, as shown here (see Mondrian screenshot) and as asked here, too?
In Mondrian, this works perfectly well by selecting any attributes within the data overview window and then pressing CTRL + SHIFT on a data point in a scatter plot for example. In iPlots, there is no way to select the attributes like this. I thought iplot.setExtendedQuery() is the key. However, there are no examples on how to use the query string.
Selecting a point plus printing the attributes using sth in the veins of mydata[iset.selected(), ] can't be the only way to go...
