QUESTION
My chart y labels are cut off and by trying different solution found on stackoverflow like adding spaces in labels or setting layout padding did not solved the problem.
The code
...ANSWER
Answered 2022-Jan-26 at 16:52The sampleSize
property in your y axis config is the culprit, since you put it to 1
it only looks at the first tick for the length that it can use. But other data in your array is way larger so it wont fit. Removing this property or making it a bigger number so it would sample more ticks will resolve your behaviour (removing will give most consistent results).
QUESTION
I am trying to style using theme overrides as laid out in the documentation here:
I have the following code sandbox:
...ANSWER
Answered 2021-Oct-14 at 22:22This looks like a bug to me (or at least missing a feature that is reasonable for developers to expect to be there). The issue is that Select doesn't define any styles of its own at the root level, so it doesn't leverage the code (which would be a call to MUI's styled
such as here for the select
class) that would take care of looking at the theme and applying the corresponding style overrides. I recommend logging an issue.
There are a couple possible workarounds.
Workaround 1 - Target theselect
CSS class
This approach may work, but it depends on what all you are trying to do since this targets a child of the root element.
QUESTION
I have created one custom Animated bottom sheet. User can move the bottom sheet scroll up and down. Inside my bottom sheet, I have used flatList where I fetched the data and render the items as a card. Up-till now everything works as expected but I had an issue Flatlist scrolling. Inside the bottom sheet the Flat-list does not scroll. I have made hard coded height value 2000px
, which is really practice and also FlatList's contentContainerStyle
added hard coded paddingBottom 2000
(also another bad practice). I want to scroll the FlatList based on Flex-box
. I don't know how to fix this issue.
I share my code on expo-snacks
This is my all code

QUESTION
I have a pandas data
frame with questions (type = 1
) and answers (type = 2
). col section_id
and type
are integer. all other col are string. I want to merge the "answer rows" with their corresponding "question rows" (equal values in section_id
) before appending some of the answer rows' values as extra columns (Ans
, ans_t
) to their corresponding "question rows".

QUESTION
I'm trying to create a standalone type in TypeScript that can be used to represent a single valid HEX color code as a fully type-safe string.
My attempt is below, which falls short due to not actually being a standalone type, which is what I would hope to achieve.
...ANSWER
Answered 2021-Aug-13 at 06:54You probably already tried to do it the naive way, where you make a union of all the possibilites, and it does actually work for a three-digit hex color, but not for a longer one (see code below). I suspect, to answer your question directly, that it's impossible to make a 'standalone' type that works for all six-digit hex colors, because this would have to be a union of millions of elements.
QUESTION
When optimizing, GCC seems to bypass wrongly a #define
test.
First of all, I'm using my own link.ld linker script to provide a __foo__
symbol at the address 0xFFF
(actually the lowest bits, not the whole address):
ANSWER
Answered 2021-Jul-15 at 16:14Unless optimizations are completely disabled, both gcc and clang are prone to behave nonsensically if code performs a comparison between an address which is based upon an external symbol and an address which is not based upon that same symbol. The issue extends beyond treating such comparisons as yielding an Unspecified Result, and may result in code behavior which is consistent neither with the comparison yielding true nor with it yielding false.
QUESTION
I have the following snippet where I am accepting the details via a multi step form. The problem is that currently it is accepting only the text input fields. As you can see that the array of questions contains the type of questions where:
- Question no.1 is just fine as text input as it would accept name.
- Question no.2 should be a radio button as it would accept gender.
- Question no.3 should be text input field again with a datepicker for DOB,
- Question no.4 should be a select box for selecting a country from the list and lastly,
- Question no.5 should have the input type as checkbox for selected all those user is interested in seeing (male, female, other).
However, I am stuck on implementing this as I am new to JavaScript. How can I implement this?
The concerned part of the JavaScript is:
...ANSWER
Answered 2021-Jul-15 at 16:14Looks like you're not defining the type in the questions array. This line is defaulting every input field to text because it couldn't find the type.
inputField.type = questions[position].type || 'text'
QUESTION
I made this iPhone in HTML (Please do not pay attention to the spaghetti code, and it's in german, if it is necessary i can translate it with pleasure):
...ANSWER
Answered 2021-Jul-09 at 01:07We can seperate the two 'screen's by wrapping each in a div
with class panel
.
To make the slider scrollable, we have to apply white-space: nowrap
to force it into a single line. To make scroll-snap work horizontally, set scroll-snap-type
to x
and make it mandatory
(scroll-snap-type: x mandatory;
). This means that:
The visual viewport of this scroll container will rest on a snap point if it isn't currently scrolled. That means it snaps on that point when the scroll action finished, if possible. If content is added, moved, deleted or resized the scroll offset will be adjusted to maintain the resting on that snap point.MDN
We also set overscroll-behavior-x
to contain
which makes sure that no scroll chaining occurs to neighboring scrolling areas, e.g. underlying elements will not scroll.
We then apply scroll-snap-align: center
to .panel
. To prevent the overflowing contents in the panels, we also apply white-space: initial
.

JS Scroll-snapping (mouse drag)We can take it one step further by adding support for user drag to scroll.
For this, we don't actually need scroll-snap at all. We can do it with pure JS.
Add an event listener for mousedown
that sets isDown
to true
. Record the last position of the mouse.
Add an event listener for mousemove
that checks whether the user is currently dragging (isDown == true
). If the user is, calculate the distance from the current mouse position and the last mouse position, increment the slider's scrollLeft
by the difference, and set the last position to the current position.
Add an event listener for mouseup
that sets isDown
to false
and checks whether the slider's current scrollLeft
is bigger than half. If it is, we can use scrollIntoView()
on one panel to smoothly scroll it into the viewport.
To prevent scrolling when an app is opened, we can store the status in a variable which we set it to true
when one of the open app function is called and false
when the closeApp
function is called. In the mousemove
listener we also check whether this variable is true
.
