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

I'm a long-time user of SciChart, but it's an old version (3.1). I've just started using FastHeatMapRenderableSeries for the first time, and there is a requirement for a user to alter the chart's gradient stops. I've implemented a UI to do this (see image), which involves dragging markers that updates their respective gradient stop within the ColorMap's LinearGradientBrush. It's working in as much as gradient changes can be seen in the chart's HeatColorMap (not shown on this screenshot), and also in my "drag" control (a Rectangle whose Fill is bound to the ColorMap's brush).
The problem is that the colours within the chart itself don't change - perhaps I was being a little too hopeful that this would happen automatically! Is this possible, or will I have to recreate the series each time there has been a change to the gradient?
We actually have this working in a later version of SciChart. Im not sure which version exactly but it was introduced at some point. Have a look at this forum post which discusses a bug in the heatmap color map binding in v5.
In the v6 examples suite, you can drag the heat map legend and recolour the chart automatically, so we know in principle this works.
Very cool image by the way!
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.
ExtJS has a very useful layout mechanism called flex. It works by summing all the things on a row or in a column. Then the space is parceled out using the flex value divided by the sum of all the flex values. This results in a layout like below:
The Red box is an hbox layout, the blocks E and F have the given flex values that sum up to 3, so E gets 1/3 the width of the screen, and F gets 2/3rds.
The Blue box is another hbox layout, where all 4 pieces (A-D) have the same flex so each one gets 25% of the space.
What isn't shown is the surrounding vbox layout where the blue box has a flex of 22 and the red box has a flex of 78.
Is there anything like this kind of layout in Angular? If there isn't, how would you put this together in Angular?
Additional information based on some of the answers below:
I want to be able to replace extjs with Angular. To do that I need some functionality that I have in extjs that I don't know exists in Angular. I've found ways to watch for screen size, change to adjust the overall display size, but I haven't seen a good example yet of a directive that essentially introspects its constituent directives for this flex value and sets their size based on a size change event of the container. Flex doesn't work from inside the divs, it works inside the container of the divs, because it has to go across all the divs in the container to divide the space correctly. I haven't seen an angular directive that does this yet.
I have no actual development experience with Angular yet (I've watched many of the videos from http://egghead.io, I've read documentation and tutorials, listened to this podcast: JSJ-Angular) and so I don't know if this is something that is easy to solve, or hard to solve, or if someone has already solved it. This flex layout is wickedly cool and easy to use, in fact for full page apps, I'm not sure there is an easier way to lay them out so that they stay full screen and are malleable to screen size changes. Grid systems are great for some things, but they don't address what the flex system addresses.
I'm trying to see if there is a way to leap from extjs to Angular without really making my life difficult.
Additional discovered information:
Looks like flex is becoming a display type now in the form of the CSS display: flex or display: inline-flex (with prefixes at the moment)

Interesting to see the illustration calls it the Holy Grail Layout example. Of course IE won't implement it right, or in a timely fashion, but my customers don't mind using Chrome if it gets the job done.
Turns out someone has create one and it does MOST of what I was looking for.

You missing the point. Angular is only JS library that helps you with:
modularization your code
allow you load content asynchronously
change content using "magic" (two-way bindings)
etc.
It doesn't describe style of your site. You have to do it by yourself or use one of popular fluid/responsive CSS frameworks, i.e.:
Bootstrap by Twitter
Zurb Foundation
Inuit.css
Pure
Gumby
Metro UI
etc.
Just choose yourself and then apply to your site. Using that also make your design independent from JS (which is very bad) and JS framework (which is 9th circle of hell).
I need to display many markers on a WPF image. The markers can be lines, circles, squares, etc. and there can be several hundreds of them.
Both the image source and the markers data are updated every few seconds. The markers are associated with specific pixels on the image and their size should be absolute in relation to the screen (i.e. when I move the image the markers should move along with it, but if i zoom in, they should take the same space of the screen as before).
Currently, I've implemented this using the AdornerLayer. This solution has several problems but the most significant one is that the UI doesn't fare well under the load even for 120 such markers.
I wanted to ask what would be the best way to go about implementing this? I thought of two solutions:
Inherit from Canvas and make sure it is invalidated not for every
added marker but for a range of markers at once
Create a control that holds an image and change its OnDraw to draw all the markers
I would appreciate some pointers from someone with experience with a similar problem.
Your use case looks quite specialized, so a specialized solution seems in order. I'd try a variant of your second option — extend Image, overriding its OnRender method.
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.
