core-plot

In the iPhone application Roambi, the pie chart shown can be animated to rotate with the user as if rotating a disc. We can hold and do lot of stuff with that. Someone mentioned that the Roambi app was developed using core-plot library: What library use Roambi app iPhone to draw chart? How can I manipulate a pie chart developed using Core plot? A quick look at the Core Plot source code reveals that CPPieChart 's inheritance looks like this: CPPieChart : CPPlot : CPAnnotationHostLayer : CPLayer : CALayer So you can see that in the end, CPPieChart is just a heavily subclassed CALayer . I might

I am using the Core Plot framework, and attempting to work through the example applications. Are there any tutorials for using this framework? Specifically, how do you provide labels for X and Y axes in a chart? Unfortunately, given the fact that the API of the framework has not yet stabilized, there aren't that many tutorials out there, and several of the ones that do exist are already outdated. The example applications really are the best sources to see how to work with the framework. For example, to provide custom axis labels, take a look at the CPTestApp-iPhone's

Are there any alternatives to Core-Plot for drawing graphs in iPhone SDK? I am having hard time integrating core-plot in my app. Lot of issues. Can you please suggest some alternatives to core-plot? meetpd Some of the alternatives that I found were: http://sebkade.wordpress.com/2010/05/06/basic-graph-class-for-iphone/ http://www.rgraph.net/ http://www.ivisualization.com/ http://www.vvi.com/apps/vvidget http://cocoacontrols.com/platforms/ios/controls/tapku-graph (thanks Sudo for this link) http://www.shinobicontrols.com/ (latest addition) https://github.com/sweetynebhwani/deSimpleChart These

Here is how my graph looks like: I wan't the y axis to have an interval of 50 so i try doing this: var axisSet: CPTXYAxisSet = CPTXYAxisSet(layer: graph.axisSet) var y = axisSet.yAxis y.majorIntervalLength = 50 But majorIntervalLength doesn't seems to exist Swift doesn't support NSDecimal values. We've made some changes to the Core Plot API, replacing NSDecimal with NSDecimalNumber . The changes are on the release-2.0 branch and not in a release package yet. See Core Plot issue #96 for more discussion of the issue. 来源： https://stackoverflow.com/questions/27204557/coreplot-with-swift-there-is
