I recently did a global install of create-react-app and am having an issue where sometimes, when I'm working on a project, instead of editing directly what I have rendered in , it creates this container around the entire app.

Upon further inspection it looks like it is an which is rendered in the browswer as this:

I am working on a React app where i want to display charts. I tried to use react-chartjs-2 but i can't find a way to make it work. when i try to use Pie component, I get the error: Error: "arc" is not a registered element.

I did a very simple react app:

• npx create-react-app my-app
• npm install --save react-chartjs-2 chart.js

Here is my package.json:

I made the following 25 network graphs (all of these graphs are copies for simplicity - in reality, they will all be different):

I want to do a simple calculation for each row by group, but I need to refer to a previous row that meets certain conditions. I want to create a new variable, results. For each row in each group, I want to find the closest row above where tag == "Y" and code is not NA. Then, I want to use the value from that row, and multiply by the value in the current row.

Minimal Example

I am trying to show only the first two rows of a CSS GRID.
The width of the container is unknown therefore it should be responsive.
Also the content of each box is unknown.

My current hacky solution is to define the following two rules:

• use an automatic height for the first two rows
• set the height of the next 277 rows to 0 height

grid-auto-rows: auto auto 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;

I tried repeat() like this: grid-auto-rows: auto auto repeat(277, 0px) but unfortunately it didn't set the height to 0.

Is there any clean way to repeat height 0?

EDIT Keep in mind that each cell can have a different width and height. This is not the same thing as this post: CSS-only masonry layout, see guide lines of the reference picture:

there are about 19 columns and 17 rows made by guide lines and tiles placed in virtual 5×5 base grid overlap it in both axis.

I want something between a grid and a flex layout. Grids are limited by cell size and flex is more powerful, but (what I know of it) is limited to direction. I want to have different cell sizes, each 5 of them summing to the same width, and 5 columns summing to the same height. Like the image below.

Is there any way of achieving a similar layout using CSS?

This is all I got until now:

HTML:

I am using SDL2 for the first time, and when I try to create a window, it's not displaying. The only sight of the window is an icon spawning in my dock (Image of the icon, SDLTest.out is the name of my executable file). I found out that it spawned when SDL_INIT()was called.

I tried updating the window, changing its color and adding the flag SDL_WINDOW_SHOWN, but none of these solutions worked. I even pasted a code from the Internet, but it didn't work better.

Here is the code that I pasted:

I borrowed the R code from the link and produced the following graph:

Using the same idea, I tried with my data as follows:

I've run into this issue today, and it's only started today. Ran the usual sequence of installs and pushes to build the app...
