waterfall | produces Page Load Waterfalls using the Resource Timing API | Build Tool library

I am trying to create a table (150 rows, 165 columns) in which :

• Each row is the name of a Pokemon (original Pokemon, 150)
• Each column is the name of an "attack" that any of these Pokemon can learn (first generation)
• Each element is either "1" or "0", indicating if that Pokemon can learn that "attack" (e.g. 1 = yes, 0 = no)

I was able to manually create this table in R:

Here are all the names:

I want to create a table that looks like this:

So far I have a table I created to get the value counts but I need help with creating a table that calculates the total value of row 0 and 1. I'm using this dataset: https://github.com/fivethirtyeight/data/tree/master/bob-ross

Code:

I am following Colt Steele's React course. Sadly, the course is outdated so I chose to migrate to the latest versions of libraries myself.

Coming to the point, I am now facing this error where I am not able to extract URL params using the useParams hook in my functional component. I am pasting my code below for the community to check.

I'm new to react and I'm having trouble preventing the components from re-rendering when I navigate to a different page. Im trying to navigate to my Signup and login page which have nothing but a line of text which is the ONLY thing I want displayed.

The problem is that the Navbar re-renders each time I navigate through the links. I tried different times for react-router v6 but the Navbar is always re-rendering below when I navigate. I simply want the text shown only on the screen but the navbar still shows up

I did not include the Navbar as a Route in my code, but it is being shown every time I navigate to a different link as well as my image slider with react bootstrap carousel.

Hi and thanks for reading me I'm working with a bar chart on R with the Echarts4r package, but I want to do a waterfall chart and I don't find an option to do a plot like the following on the image:

It's possible to do this chart type? The code I'm using for now is the following:

I am creating an application with react. I have to fetch several data. This is my fetch statement:

I am trying to create a for loop that at each iteration updates the params of an OpenLayers map and once it is renderedcomplete it extracts the context of the mapcanvas and adds it to a GIF object. I need these to run synchronously as to always allow the map and layers to rendered and only then for the context to be added. My hacky solution at the moment is to use a fixed time setInterval, but as suggested in this question I should use async/await/Promises. My question is how would I go about wrapping my functions in a Promise and ensure they execute in a sequence while maintainning access to the context (this) of the vue app?

My for loop would look something like :

I'm trying to add a "total value" column in my waterfall chart but I'm not why I can't do it as this data is in my table. See my actual table:

I have a web page with two canvas elements stacked on top of each other. This is the basis for some functionality that lets me "erase" the top canvas to reveal an image loaded into the bottom canvas. The functionality works well.

What I'm trying to do now is trigger an event once the top canvas has been completely "erased" i.e. all of the pixels for the top context are transparent. I've found ways on SO to check a particular pixel's alpha value via getImageData but I'm trying to figure out a way to determine when the very last pixel's alpha value = 0.

I've included my code as well as an unfinished attempt to do this with a for and if loop (but this seems to not be the best approach). Another issue I've discovered is that when I use getImageData a thin grey border appears around two edges of my canvas.

Thanks for any help in advance!
