问题 I created the pie chart in SSRS as given below. I enabled the labels by right clicking on pie chart and click show labels. When I preview the chart I cant see all the labels.

问题 I'm trying to create a pie chart in swift, and would like to create the code from scratch rather than use a 3rd party extension. I like the idea of it being @IBDesignable, so I started with this: import Foundation import UIKit @IBDesignable class PieChart: UIView { var data: Dictionary<String,Int>? required init(coder aDecoder: NSCoder) { super.init(coder:aDecoder)! self.contentMode = .Redraw } override init(frame: CGRect) { super.init(frame: frame) self.backgroundColor = UIColor.clearColor()

问题 suppose I have 4 slices having 20%, 30%, 30% and 20%. If I make 4th slice(20%) inactive, the other slices should adjust themselves and occupy 100 %. how to do this in highcharts? Thank you. 回答1: I don't think it's possible to alter this behavior. Instead you need to remove the point all together for the other slices to add up to 100. Here is an example that shows the difference between legend-toggle and point remove: jsfiddle 回答2: I think this should be the standard behavior :) opts

How to plot a pie chart with the first wedge on top, in Python? [matplotlib]

阅读更多关于 How to plot a pie chart with the first wedge on top, in Python? [matplotlib]

问题 How can a pie chart be drawn with Matplotlib with a first wedge that starts at noon (i.e. on the top of the pie)? The default is for pyplot.pie() to place the first edge at three o'clock, and it would be great to be able to customize this. 回答1: Just because this came up in a Google search for me, I'll add that in the meantime, matplotlib has included just this as an additional argument to the pie function. Now, one can call plt.pie(data, start_angle=90) to have the first wedge start at noon.
