in this example you see the the intial zoom of the series set to 0.1.
But the graph is not rendered in the center of the viewport.
How do I accomplish that?

I have a triangle polygon filled with color and low opacity. That was no problem so far.
What I'm trying to achieve looks like this (without points and lines). It is basically triangle polygon with fill color but opacity smoothly lowering from one of the triangle apexes.
Is there any way to achieve this with mapbox? Thanks!
There is no easy, built in way to do this with Mapbox GL JS.
The best way I can think of is to create a Marker (an HTML object anchored at a specific lat/lng) to draw the shape. You will have to do some maths to translate the coordinates of the triangle's vertices into screen coordinates. You will also have to update the calculations if the viewport zooms or rotates.
I was asked to see if I could using leaflet draw a circle and as I'm drawing it show what the current expanding radius is. Either as a tooltip or write it to a page label. I noticed the circle option has a showRadius option but can you capture this value as your drawing the circle?
Kind of like the measure tool that uses the drawing plugin can show your distance as you move the mouse.
This way the user can see how big their circle is as they are drawing it.
Any ideas, examples, hints?
Leaflet.draw plugin does that.
Check out this demo
However, it shows radius only when you create a circle. Unfortunately, not when you edit it.
I am trying to display a progressbar using EaselJS.
My progressbar background-image is 200px, and fully displaying that would mean the progress is at 100%.
How can I show only draw a percentage of an image in EaselJS? And is it possible to animate/tween towards more %?
You are looking for a mask: http://www.createjs.com/Docs/EaselJS/classes/DisplayObject.html#property_mask
Here is an example on how a mask could be used: https://github.com/CreateJS/EaselJS/blob/master/examples/Masks.html
I am now using Core-plot for iPhone chart Development.
But it has some requirement i can not reach.
I am now using CorePlot 0.4, example code AAPLot to develop
Please have a look the following image, then you will know what is my problem
Thank you very much...
I really need help for this problem,
thank you
i want my result like this application
I see several questions here:
Y-axis scale: Try the CPTAxisLabelingPolicyAutomatic labeling policy on your y-axis. If that doesn't give you enough control, use a different labeling policy and use a plot space delegate to adjust the labeling parameters as the user zooms in and out.
Disappearing x-axis: Make it a "floating" axis. For example,
x.axisConstraints = [CPTConstraints constraintWithLowerOffset:0.0];
Maximum zoom level: Use the globalXRange and globalYRange plot space properties. If you need more control, you can use a plot space delegate.
Scroll bars: This isn't directly supported. You could use a plot space delegate to update the scroll bar position.
Is there a way to rotate an image symbol in the legend widget??
I'm using a few vertical lines in my graph to show the location
of a leak on a chart. The legend shows these lines as horizontal
which is fine but, it would be better to rotate it and show
a vertical line. That would be wayyyy more intuitive to the user.
Thx!!
John
Currently it is not supported.
