HTML element hides D3.js SVG

Asked 2021-Mar-31 at 19:03

>> Problem: The Code below contain 3 nodes with an working on("click", function()){}. If clicked a modal window appear. But the modal window is not drawn top of the SVG, instead the SVG area is pushed to the bottom. Further if a node is dragged to the top, it disappear behind the section background.

If I create, in the HTML body, the SVG first, I can´t click any button or even use the selection. This problem could be solved by adding pointer-events: none to the canvas. But this brings other problems.

Any idea, how I could solve this chicken and egg problem?

...

ANSWER

Answered 2021-Mar-31 at 19:03

There are a couple of problems to fix in order to achieve what you want:

If you want the modal to stop pushing the content down you need to replace position: relative with position: absolute and center it using left: 0 and right: 0
Further if a node is dragged to the top, it disappear behind the section background. It is not disappearing behind, the issue is the SVG width, remove the width declaration from the js and use width="100%" directly in the svg element
In order for the chart to stay behind it just needs a z-index < than the modal

This should work:

I am want to change my selector arrow icon. So far I disabled the default appearance and added the arrow, from the link, below:

Organizing a csv file of multiple datasets into a list of Pandas dataframes

Asked 2021-Mar-29 at 06:15

I have a csv file, containing results from a Computational Fluid Dynamics (CFD) simulation (a sample of my csv file is attached as a google drive link; file size: 226KB). In particular, the csv file has information (x, y and z coordinates and velocity in three directions, so a total of six columns) about multiple streamlines (number of streamlines may vary depending on the case). Information about streamlines are separated by two empty rows (see the sample csv file). Streamlines have may have different number of rows.

I need to read this csv file, and organize its data into a list of Pandas datafreames, like:

QUESTION

C Socket Programming: Socket connects, but cannot write through socket to server

Asked 2021-Mar-28 at 19:13

I'm working on a simple client/server implementation in which the client connects to the server based on the command line argument that specifies the hostname to search for a socket to connect with on (I just input localhost) and then sends a singular string that is reversed by the server, and then this reversed string is sent back to the client, and the reversed string prints. I am able to connect to the socket that lives at localhost (the client) but writing through the socket fails, and I am not sure why.

This is the server code: It has a built in reverser function that manually reverses a string and then writes it back through the socket to the client after reading in the original message that was written to the server by the client

try with send() and recv() instead of write() and read() and the next problem is these functions most of the time fail when you want to get more than four byte so you need to do something like this:
(you shouldn't send or take all of them at once.

You should not allocate variables in the header, it should properly be carried out in the init block (this is where you initialise and can properly allocate variables). You are also using OrderSymbol() without selecting an order so this will always be empty.

Bootstrap vue cards bottom buttons to be aligned

Asked 2021-Mar-14 at 07:35

I am using bootstrap vue with vue to code a 4 by 4 card. Currently the title in one of the card is messing with one of buttons on the bottom of the card. The media width for the below is around 1000px.

Please refer to the image below

However when I change the title to a shorter Title, it is aligned. Please refer to the image below

I know it has something to do with the width but I can't seem to figured out what is causing it.

Steps that I have tried to solve the issue is using flex grow on the parent and word wrap for the title but still nothing. Hopefully someone can shed some light.

I think the problem is image sizing. To control that we can give a max-height: 112px styling to the card-img. But we have to give it in a size bigger than 991px. So that we could protect our image sizes when flex-direction returns to column. Here what I've added to your style;

Is Pyvista a complete library already? [January 2021]

Asked 2021-Feb-18 at 01:35

I was searching for new visualization libraries in Python, and I learned about the existence of Pyvista. The examples I've seen look amazing.

I used to work with Mayavi a few years ago, but Pyvista seems very tempting. Are the features in Pyvista really as well-rounded as traditional libraries like Mayavi, etc.?

The question can seem opinion-based, but sometimes new libraries need a few years to become complete. I learned this the hard way with some CAD packages.

I intend to use Mayavi to post-process results from CFD simulations (computational fluid dynamics). Please let me know your opinions.

Thanks in advance,

...

As PyVista is just a wrapper for VTK it's safe to say that you are not restricted in what is possible.

I found the move from Mayavi to Pyvista really straight forward. The library has a couple of functions that allows you to convert your existing data structure into VTK friendly structures quite easily. And if you were a fan of Mayavi's pipeline work there is something similar in PyVista where you can add on different things to do plotter.

I hope that helps. Also, join the slack channel if you want to ask any questions / see what other people are using it for.

ANSWER

Answered 2021-Jan-12 at 17:49

To quote the Bash man page, one of the more common shells implementing /bin/sh:

for name [ [ in [ word ... ] ] ; ] do list ; done
The list of words following in is expanded, generating a list of items. The variable name is set to each element of this list in turn, and list is executed each time. If the in word is omitted, the for command executes list once for each positional parameter that is set [...]

Thus, if you omit the in ... part, the loop will iterate over the positional arguments ($1, $2, ...) which are set in the current context. In your case, this would be the list of wildcards given as command line arguments.
