core-plot

问题 Situation: Scatter points/date, each month could contain a variable-number of data (points). Desired: Have fixed-width months along x-axis whose columns contain their respective points (i.e. same-number of points/month). Can Core-Plot extrapolate missing data points to equalize the distribution of data/month? How would that be done? I want the fixed-width months to coincide/sync with their respective data points (and hence, may necessitate the filling in of missing data points; i.e., months

问题 I was really impressed, and really grateful about the answers I recived last time I asked here. I have this problem with Core Plot. I want to have a CPTGraphHostingView inside my UIView so I can have things like labels and scroll views below it. I am using XCode 3.2 by the way. How do I do this programmatically? Or with the Interface builder if possible.(I need the instructions to be detailed as im I bit new to this sort of thing) Thanks for your support. 回答1: If you want to add a core plot

问题 I am trying to use the CorePlot 0.9 binding for monomac, but that seems to be a hard task. The monotouch sample builds and runs without any problems, but I don't need that one. Since only a CorePlotiOS.dll was present in the binding, I had to build one for osx myself, but first of af all, no bmake.exe was present, so I had to download the monomac source and build it myself first. Then I tried to build the CorePlotOSX.dll but that caused some compilation problems. Looking at the build-script

问题 I would like to create a CorePlot graph with dynamic bands ( changing as the time goes along ), a little bit like this ugly drawing here (forgive me for the quality): Basically the band colouring should change based on some values/criteria. The yellow band can be wider or thinner and so can the white and green band. In other words these bands need to have dynamic width This is the current way I set the y graph band colouring, however if I dynamically change it it does not work as it changes

问题 Currently I am working on already established application which uses Core plot and in specific its using ScatterPlot to draw a graph. This graph is drawn with values obtained from connected bluetooth device so the graph is dynamically drawn. XY graph with X axis having time value and Y axis having value from BLE device. Now the requirement is to add an out of range value with a label "OL" in the graph and its not a fixed constant value for the bluetooth device(Its more of a state set in model

问题 I have a graph and I wan't that the x and the 2 y to start at 1 not 0. ![enter image description here][1] This is how i setup the plotspaces: //plotspace 1 var plotSpace: CPTXYPlotSpace = graph.defaultPlotSpace as CPTXYPlotSpace var xRange = plotSpace.xRange.mutableCopy() as CPTMutablePlotRange var yRange = plotSpace.yRange.mutableCopy() as CPTMutablePlotRange xRange.length = self.maxX yRange.length = maxPoids plotSpace.xRange = xRange plotSpace.yRange = yRange //plotspace2 (second y) var

问题 I'm trying to use CorePlot to draw a simple plot. I'm working from this tutorial, but when I type this in my ViewController.h : <CPPlotDataSource> { CPXYGraph *graph; } I encounter an error: CPTAnnotation.h file not found What might be the cause? 回答1: The Core Plot class prefix has changed from "CP" to "CPT" since that tutorial was written. If you're using anything later than Core Plot 0.3, you'll need to make the change in your code, too. There are several other needed changes that are

问题 Has anyone managed to use core-plot from wax? I have been trying recently, but got stumped on NSDecimal. Wax does not want to deal with it. How can i get around this issue? 回答1: I succeeded in working around the NSDecimal system by rewriting the parts which used it. 来源： https://stackoverflow.com/questions/6475890/integrate-core-plot-and-wax
