core-plot

What I would like to accomplish I am using Core Plot (1.1) to draw a bar chart and I would like to present a popover with further details below the bar which has been selected (tapped) by the user. Code My code looks like this: - (void)barPlot:(CPTBarPlot *)plot barWasSelectedAtRecordIndex:(NSUInteger)idx { NSNumber *yValue = self.values[idx]; NSLog(@"barWasSelectedAtRecordIndex x: %i, y: %@",idx,yValue); NSDecimal plotPoint[2]; NSNumber *plotXvalue = [self numberForPlot:plot field:CPTScatterPlotFieldX recordIndex:idx]; plotPoint[CPTCoordinateX] = CPTDecimalFromFloat(plotXvalue.floatValue);

How can I add Legends in Core Plot framework? I am greatly appreciative of any guidance or help. Ahmad Kayyali There is no Legend class yet. You can fake it using an image sometimes, but it is not in Core Plot yet. Check drewmcco Comment Legends have not yet been implemented in Core Plot. You're more than welcome to contribute an implementation of them to the framework. In the meantime, you could construct a custom UIView with UILabels and colored lines to act as the legend for the graph, then add it as a sibling to the graph (not a subview, or it will not be rendered properly) and order it to

According to the Ray Wenderlich tutorial , I done the following : Step 1 - I downloaded CorePlot_1.4.zip on the official website Step 2 - I added to my project the CorePlotHeaders folder and the static library named libCorePlot-CocoaTouch.a (checking “Copy items into destination group’s folder (if needed)” ) Step 3 - I added into Other Linker Flags field the following : -ObjC Step 4 - I checked into Link Binary with Libraries if libCorePlot-CocoaTouch.a and QuartzCore frameworks were here Result : When I compile my project, it works fine when I'm using Iphone Retina (4-Inch) . But when I'm

I need to create graph which is "Heart rate vs time". in xAxis I am showing time which is in format of "HH:mm:ss" and at y Axis its decimal value. My code is as below : data source for graph: var graphData:[(String,Double)] = [] let data = ("17:56:35",Double(65)) let data1 = ("18:04:13",Double(95)) let data2 = ("18:8:35",Double(25)) self.graphData.append(data) self.graphData.append(data1) self.graphData.append(data2) Set up graph and plot data code: func setGraph() { let tts = CPTMutableTextStyle() tts.fontSize = 75.0 tts.color = CPTColor(CGColor: UIColor.blackColor().CGColor) tts.fontName =

I'm almost done with a core-plot graph I've been working on for a couple of day now. There is something I am still not able to do (and I cannot find documentation on this), is to change the x axis labels to what I need. Today, I have an x axis with integer label beeing displayed every 5 values: "5 10 15...", I need to have labels coresponding to the last 24 hours. For instance if it's 15:00, I would need labels like: "15 16 17 ... 23 0 1 2 .. 15" I was thinking of using a NSArray for this and passing it to the plotSpace.xRange but I do not know if this is the good way to do it. Here is my code

Is there some sample code or a tutorial out there about how to draw a line chart using the Core Plot framework? I can't find anything using Google. If you have downloaded the framework , go to the examples directory within your checked-out version. There are several examples there, including CPTestApp-iPhone (which demonstrates line, bar, and pie charts), CPTestApp-iPad (same, but for the iPad), StockPlot (which downloads stock charts and plots the line graphs for them), and AAPLot (which grabs Apple's stock price and plots it using an open-high-low-close chart). These examples are updated as

I'm using the instructions here to integrate Core Plot into my iOS Xcode 5 project and am having no end of issues. I tried using the Static Library Install but it seems this refers to 1.4 as there is no directory called CorePlotHeaders though if I try to use 1.4 I run into runtime issues. I've then tried to drag the CorePlot-CocoaTouch.xcodeproj as described in the Dependent Project Install but this only copies it as if its a file and not the whole project. Is there more current instructions for using it as a static library or how am I copying the project incorrectly into my project? If you
