QUESTION
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:

Answered 2022-Apr-03 at 13:03Ok, this was more complicated than I thought because the documentation is dreadful but I was able to get it running on this stackblitz
To be able to call events manually or programmatically on the chart we need to get the reference to the chart object. To get the ref on the child component we can do something like this:
QUESTION
I have a VBA script to drill down into a cell containing a SUMIFS, and then filter the raw data sheet to isolate the rows pertaining. The script works on a cell that has just one SUMIFS.
Some of my cells contain an IF statement with two SUMIFS (depending on what variable the IF is).
I am trying to find a way to first find the relevant SUMIFS in the IF statement, and then use the correct one to then filter.
My code:
- Double click script loaded on worksheet to trigger the macro (this is working)
ANSWER
Answered 2021-Dec-02 at 18:06I came up with a function that can split the IF formula into it's TRUE and FALSE parts and return relevant part based on the expression. So if the expression is true, the function returns the True part of the IF Formula.
The function I have made is not a robust function, and it only works if the given formula is in the structure of "=IF(< expression >, SUMIFS(...), SUMIFS(...))". And it evaluates the expression with the ActiveSheet.

I have a scenario where I have to use Rangechart and Column Chart in a single page and I need to call Highchart JS files asynchronously for both Chart type.
Rangechart works fine and drill down also works fine, but drill down for Column Chart does not work.

QUESTION
I am reviewing some React Js basics and I need some clarifications about the use of the constructor method within a react class based component. My normal practice is to declare a class based component and define state without using the constructor, like so:
...ANSWER
Answered 2022-Mar-16 at 13:06The constructor is not necessary, if you don't need it.
You might need a constructor e.g. if you need to bind a method to the class instance (so that this keeps pointing to the
class instance if you pass the function over to some other execution context):
QUESTION
Context: I (as a soil researcher) have been working on a script to automate the process of acquiring data from a large database site in the Netherlands.
The site is called https://www.dinoloket.nl/ondergrondmodellen
whenever you select a location you can get an expected soil build-up for different models. the model that I use is the regis v2.2. that shows different lithologie formations.
so far i have been able to create a script that selects the correct model, inputs a address and export the depths of the different layers
Example of what the site gives as layer output
in the image it also shows a tooltip that is different for each color in the column. I would like to be able to access this text however, it keeps disappearing.
I have read other related questions however, what is different is that the tooltip text is variable depending on where you are in the column.
in the image you can see that the tooltip (id="columns-tooltip") has a changing message whenever the location on the tooltip changes.
Does anybody has an idea on how to access the text "Complexe eenheid, bestaande uit een afwisseling van zandige klei, midden en fijn zand, klei en veen en een weinig grof zand"
I am aware that the question is vague, however some pointers in the right direction might already be helpful.
Thank you

QUESTION
I need to create a treemap with round corners as shown in the image
I have tried:
Changing plotOptions.treemap.borderRadius set the radius for each box instead of the entire plot.
Using chart.borderRadius has no impact on the graph, I believe it is so because the plot itself is not going till the edge of the chart.
The rounded-corners library by highcharts does not work with treemaps. It is working well with bar charts
Any direction on how to achieve this is appreciated. Here's a jsfiddle of treemap for reference.
Here are options I have tried

QUESTION
I'm new to the webdev world and want to learn ReactJS. I followed a tutorial I found on YouTube made by Traversy where he makes a task tracker and now I want to make some changes to it to learn and practice some more.
I want to use context for the appointments (originally named tasks in the tutorial), add a calendar with react-calendar and use react-router-dom. I got stuck for a while trying to make the list render, because it only rendered "empty". Later on found this post with a similar issue to mine: Only run a useEffect fetch after first useEffect fetch has fired and setUser in context
I changed bits of my code based on that post and now it does render the appointment list, but I don't know why it didn't work before and I'm unsure on why it does work now. I don't even know if I'm using context correctly or just prop-drilling. Help would be greatly appreciated. Thank you.
Also, sorry if my code is a mess, I'm new at this.

QUESTION
We have a series of .NET Core console apps that are installed in a particular directory:
...ANSWER
Answered 2022-Jan-25 at 00:31Are the apps published as Single File Applications? If so, the documentation have some pointers.
Looking at the fact that it's extracting 3rd-party libraries, I'm guessing this may be relevant:
Previously in .NET Core 3.0, when a user runs your single-file app, .NET Core host first extracts all files to a directory before running the application. .NET 5 improves this experience by directly running the code without the need to extract the files from the app.
And this explains the location:
If extraction is used the files are extracted to disk before the app starts:
- If environment variable DOTNET_BUNDLE_EXTRACT_BASE_DIR is set to a path, the files will be extracted to a directory under that path.
- Otherwise if running on Linux or MacOS, the files will be extracted to a directory under $HOME/.net.
- If running on Windows, the files will be extracted to a directory under %TEMP%/.net.
