React.js Circular slider with two thumbs - reactjs

I am trying to build a circular slider with two thumbs(knobs). The requirement is very specific our client wants it to be circular in shape and should have two knobs .I tried changing the shape of MUISlider to circular(already supports two knobs not circular though) but in vain.

We tried this but doesnt support two knobs - https://dmitrymorozoff.github.io/react-circle-slider/
Please find attached image for refrence help me in finding something that suits our requirement .

You can try to use the roundSlider plugin which supports lots of customization. Check the below demo for the circular slider with two thumbs example:

react-virtual variable sizing with images not calculating on initial load

I want to render a virtualized list of images with variables heights, my current implementation is following the variable example on tanstack docs, but adding a random height src image and loading that instead of text as the content for the row item.
This is not working great and is a bit glitchy. Im using a best guess estimateSize but was hoping for a system that would fully calculate this for me.
The height is completely off until you scroll at least once, then the image heights seem to get calculated. Otherwise, once you start scrolling, the performance here is pretty good.
Any feedback on this implementation (no idea if this is how it's intended to be implemented), or indication on how I can fix the problem would be appreciated. Thanks!
My demo here:
https://codesandbox.io/s/boring-ishizaka-yiywvo?file=/src/main.jsx
p.s if you know how to achieve this with react-virtualized (with CellMeasurer) also keen to hear/see it. I've struggled with CellMeasurer and image onLoad to calc correctly.
Ok dug through some github issues, and mashed a few things together and this seems to be working well. https://codesandbox.io/s/usevirtualresizeobserver-04-11-2021-forked-yur6we?file=/src/App.tsx
It uses a custom wrapper that leverages ResizeObserver, shame this isn't something that's exported from the lib considering this would be a very common use case.
here is a much simpler solution with the new react-virtual version
the idea is to call measureElement on img onLoad

Is there a way to have a stacked sparkline widgetColumn in ExtJS?

Ext.js has the Ext.sparkline.Bar class. Is it possible to make that bar chart stacked? I have implemented a cartesian as the widget for the widget column to achieve this effect, But it has led to very long load times (particularly when calling grid.reconfigure()). I'm wondering if a more lightweight version can be achieved via a sparkline.
The reason I'm thinking it may be possible is because of the stackedBarColor config in the Ext.sparkline.Bar class. Aside from that, I haven't been able to find anything in regards to implementing it.
Anyone have any idea?
If you look at the source for Ext.sparkline.Bar, do a CTRL+F, type: 'stacked'. You can follow the logic there. at the most basic level you can achieve a stacked bar chart by passing in an array of arrays into the values config: values: [[0,1,2,3,4,5],[0,1,2,3,4,5]]. Each array will be its own stack.

Circular Slider in WPF

I really want to create circular slider. I've been searching, but I can't find any information. So any tutorial, guide or if someone already created like this. Please post their XML code.
Instead of making a circular slider (which as #auburg points out) would be a little unintutive to use (think the old telephone dials), consider making it a dial like a thermostat:
It's functionally very similar, but has a much larger hit-test area and is therefore less easy to mess-up for the user.
Try this guide: https://blogs.msdn.microsoft.com/jerrynixon/2012/12/06/walkthrough-building-a-sweet-dial-in-xaml-for-windows-8/
A circular slider can be implemented just like a normal horizontal or vertical slider. The only difference would be that in the MouseMove event handler of the thumb during the drag operation you cannot just handle the horizontal or vertical position. Instead you have to calculate the angle relative to the center of the slider and map that to the value of the slider.

AngularJS Dynamic Slider Control

I am working on a project that requires a slider control that corresponds to an image and or a multitude of div objects. The spacing of the slider is irregular (the steps could be [1,4,7,13,14,16...]). Also the steps will correspond to specific spots on an image and or to a specific div object. The perfect slider would be dynamic and re-size with the screen but that may be actually impossible.
The hard part is that I am unable to use JQueryUI, instead I am limited to using controls that work with AngularJS.
I have been looking for hours and cannot find anything that would be a good starting point. So my question is whether anyone has found a good slider control to use with AngularJS?
This one fits some of your criteria

How to build the following visual

I am not a real designer and I would like to know if anyone have an idea how can I build the following visual :
The idea is to get 2 rings where inside I will draw secific number of pie represented as "Interactive shape or button". Base on the number of shape, they should cover the whole circle.
In addition to that, I need to be able to interact with each pie shape, and inside and oustide edge of those shape should be a perfect arc based on the circle diameter.
As I am not a perfect designer, how can I represent this visual ?
I was thinking of using a custom panel but then how to draw each panel shape in order that they gets perfect inside and ouside arc and offer interactivity with each of them ?
Thanks for your help
I would appreciate samples as well
Theres actually a Silverlight tutorial on making something exactly like this.
If you didnt want to use that, you could always do it in javascript. Here's an example using Rapheal js
I would recommend looking into WPF Geometry and how you can create custom controls (such as the Circular Gauge Custom Control over on CodeProject) using said Geometry.
I've never created a control quite like what your suggesting, but I would image you would define some form of area that can contain children and style it so that it forms the circular shape you want. Then, adding interactive regions should be as simple as adding controls to standard containers.
Here's a link to a "generic radial panel that can be used to host any items" which subclasses Panel.
