Is it possible with High Charts to blend/dissolve the colors in an animation when data changes?
The motion is already working but the barcolors won't blend/dissolve.
Unforuantely defualty it is not possible, you can configurare your animation only by http://api.highcharts.com/highcharts#chart.animation . In other cases you need to prepare your own animation mechanism, including edit a source code of highcharts.

I want to disable that first animation, because it leeks the browser in big graphs.
The documentation is frightful and I don't what to use d3 force layout, I want to keep webcola.
Thanks
I am trying to achieve a glow effect in the UI, but I can't figure out how to do it. Even after setting the color parameters to a high value (like (30,0,0) as I do normally to achieve this effect in the world), it stays the same. The effect I'd like to achieve: https://ray3k.files.wordpress.com/2016/08/preview1.gif?w=840
The UI elements in your example image are most likely just texture files and the glow effect is already in the texture. The glow effect that you achieved with setting the emission value above 1 is caused by bloom, but that does not work in UI so you have to bake the glow into the texture itself in a image editing software.
I am currently using Fabric JS but I dont like the layer/group implementation there but beside of layers fabric js has something useful I cannot find in konva js at the moment: viewports. How much work would it to implement zooming to a certain point (most often the mouse cursor) and also emit mouse events with transformed coordinates?
Use case: I would like to zoom in on a the top most layer and use drawing tools to draw on the zoomed area, so the mouse event coordinates need to fit accordingly.
Thank you :)!
I managed to get it working just by using some demo code and one coordinate scaling, great!
I am using CanvasRenderer to render numerous Sprite objects. I am mapping a texture (PNG image) to the Sprites. I'd like to be able to change the color of the texture programmatically.
With the WebGLRenderer, I can use ParticleSystem and ParticleSystemMaterial to achieve this. Here's a live demo of setting color to this texture (http://wxalert.info/private/dv/ball.png) with that technique: http://wxalert.info/private/dv/demo.html
But since CanvasRenderer does not support ParticleSystem, I am using Sprites instead with a SpriteBasicMaterial. Here's a live demo of this: http://wxalert.info/private/dv/demo2.html
I'd like to be able to set the color with CanvasRenderer just like with WebGLRenderer, but I'm not sure if this is possible.
One thought was perhaps to load the image to an HTML5 canvas element, apply the color there, and then load the canvas context from the material. But any other suggestions would be greatly appreciated.
UPDATE: Here's an example of kind of what I was thinking of doing if using the HTML5 canvas: http://wxalert.info/private/dv/html5canvas.html. Basically, I would do the color manipulation there and then just load the canvas from the material. But wasn't sure if there was a simpler or better way.
In Monotouch, I need to create a basic animation of an image moving along a path while animating it's image content with a sprite sheet or replacing the content CGImage, everything i try i can't combine both animations. I tried subclassing the CALayer and animate custom properties or combine animations in group nothing seems to work. What's the best way to produce this kind of animation?
To get a smooth animation, you want to think of what CAlayers represent: they are a handle to a texture that live in the GPU space. To get smooth animation you can control a few of their properties, but arbitrary changes like rendering the data again wont work fine.
What you should do is put all of your images in the sprite sheet, and then animate the ContentsRect property of the CALayer.
