Hi, I am attempting to write an application with core-plot that will scale the y-axis values between the smallest value and the largest value. This part works well, however when these values are drawn on the y-axis line, the values do not take up the entire length of the y axis. Statement to set up y-range: plotSpace.yRange = [CPPlotR...
I've tried setting isFloatingAxis to YES, but it just makes my axis disappear. My axis is set up as follows: CPXYAxisSet *axisSetKin = (CPXYAxisSet *)kinematicsGraph.axisSet; CPXYAxis *xKin = axisSetKin.xAxis; [xKin setIsFloatingAxis:YES]; xKin.labelingPolicy = CPAxisLabelingPolicyAutomatic; xKin.orthogonalCoordinateDecimal = CPDecimal...
I'm attempting to load a CPXYGraph into the detail view of a split view controller. I'm getting an EXC_BAD_ACCESS when it attempts to display the plot data. I create a new project based on "Split View-based application". After adding the CorePlot framework I make the following modifications: 1- add a GraphController (.m, .h and .xib)....
Hey all, I've been using Core Plot to draw some charts for an iOS app I've been developing. While core plot is excellent as a charting application, it's a performance hog when it comes to any kind of user interaction. To get around this, I started doing a lot of the following: UIGraphicsBeginImageContext(view.bounds.size); [vie...
Hej folks, currently I'm trying to write kind of a mathematical app. Reaching for my goal I'm still trying to display the graphs of mathematical functions given by the user. I calculated all the data successfully and now I want to draw the matching graph using CorePlot. But it seems the accurracy isn't quite high so how to change this? ...
I want to plot a two columns stacked bar graph, the data looks like as below, is it possible? 10/09 0.00% -36.94% 528.2502 0.0000 0.0000 333.0924 0.0000 16.1814 178.9764 10/08 0.00% -40.19% 527.7252 0.0000 3.4708 310.5550 1.6321 0.0000 212.0673 10/07 0.00% -38.09% 527.4240 0.0000 0.0000 326.5490 0.0000 8.5167 192.3583 10/06 0...
Hi, I'm using core-plot (and the barcharts) to display financial information. My problem is that whenever I use negative values, it seems that the scale of the shown graph is wrong. I'd like the entire graph to be visible, but often only a part of the graph is shown, leaving the bars cut off and sometimes not even the x-axis visible (...
I know that one can turn on scrolling in a coreplot plot space as follows: plotSpace.allowsUserInteraction = YES; but this only activates one-to-one finger to graph motion. Is it currently possible to use coreplot with a UIScrollView to achieve the elasticity effects (inertia, deceleration, bounce)? ...
I am using Core Plot alpha release 0.2 and generating a plot with custom labels. The labels are appearing in the correct location but I have no tick marks. I have tried every combination of these settings: x.majorIntervalLength = [[NSDecimalNumber decimalNumberWithString:@"5"] decimalValue]; x.minorTicksPerInterval = 0; x.majorTickLineS...
I created an application having multiple plots in a single graph(Line graph),which is in 3.2 version.In simulator it is working fine,but while Iam trying to run in my device,datasource methods of core-plot is not getting called. -(NSUInteger)numberOfRecordsForPlot:(CPPlot *)plot could anyone help me,What is the problem here? ...
Who has working example of Stacked Bars? -(void)setupBars { // Add plot space for horizontal bar charts CPXYPlotSpace *barPlotSpace = [[CPXYPlotSpace alloc] init]; barPlotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(-180.0f) length:CPDecimalFromFloat(360)]; barPlotSpace.yRange = [CPPlotRange plot...
hi all, I am new to core plot SDK, implemented core plot in my app. i need to restrict -ve part of graph. i.e always i will have +ve values for graph((1,1),(10,15),(20,15)).i need horizontal , vertical scrolling for +ve part only.So i want to restrict remaining 3 parts of graph. I tried in all ways help less, so posted here. if any one a...
