Is it possible to fill those pie areas? If so, how?
I mean, "A"(red) and "B"(purple) and the rest all.

I am creating a chart which internally is built using multiple highcharts.I want to create a custom legend for whole chart. Is there a way to show custom legend. Is yes then can someone point me to some example.
I am helping my organization put together some Pie and Donut charts using Highcharts, and some of our charts will have zero value points. Normal behavior is to not render these points out, but that leaves us with an empty chart.
So, is there a way to set a "background" circle for the Donut chart so that if all values are zero, the user still sees a gray donut (indicating "0" values)?
I don't want to use something like a background image because then it may not adjust responsively in a proper manner. Plus, we'd like the parameters of the circle to be adjustable just like other data elements in Highcharts.
Thanks for any and all advice!
Does anyone have any idea how to make a graph like this? It's basically 5 in one chart, each one represents a different dynamic value up to 100%. So like the man running icon would be 60%, scale 85%, sleep 8%, ect.
The icons in the middle obviously won't be part of the graph, they'd be a div overlayed the chart.
Can anyone help? If highcharts will not work, then what will?
I have a stacked area chart using google charts. An example is here: https://code.google.com/apis/ajax/playground/?type=visualization#area_chart
The problem is, when I hover the cursor over an area, no tooltip is displayed. I need to hover the boundary of two neighboring areas to display the tooltip.
Is it possible to display tooltips when hovering areas? If not, do you know of some workaround?
You can use a SteppedAreaChart for this. Set isStacked to true, and by default the tooltips will be shown on hovering over an area.
No, you can't spawn the tooltips by hovering over the area. There is no way easy way to work around this, as the Visualization API does not trigger mouse events on the areas.
If you want to put the effort into this, you can create custom mouse event handlers on the chart's SVG/VML code. It might be possible to extrapolate which area the mouse is in, and given that, you can extrapolate the x-axis position from the mouse coordinates using the ChartLayoutInterface, and spawn a custom tooltip based on that information. Be aware that any solution involving the chart's SVG/VML code could break at any time, as the internal structure of the charts is not guaranteed to be stable from version to version.
I'm looking for a free iOS component that allows me to draw a doughnut chart with text in the center. So far I've only used Code Plot, but that is a full pie chart.
I'm attaching an example of the requirement.
Any help will be much appreciated.
I suggest searching on cocoacontrols.com. They have lots of open source controls for iOS and Mac. I didn't se any specifically called "doughnut chart" but some of the pie charts controls might offer that option.
In fact, it seems that this one does include what you're calling a doughnut chart. It doesn't look like it has built-in support for a label in the middle, but it does create a ring-shaped chart like you want.
You could also always create a pie chart and then put a view on top of it that is transparent except for a white circle in the middle, and then put a label on top of that.
Getting a little more complex you could modify the CorePlot control and add a filled CAShapeLayer to it.
Another option is to create svg chart and use UIWebView to display it. With svg chart, you get much more flexibility with libraries like highcharts and d3js. Here's an example with donut chart:

You can embed the link or save svg and display in UIWebView. Saving svg works offline.
