title: Core-Plot does not show axes titles
body: <p>I'm using Core-Plot to visualize temperature values over time. This works fine with one exception: no titles are shown for the axes, nor are ticks labeled.</p>
  
  <p>Below you will find the code I'm using. I'm using the latest version of CorePlot-CocoaTouch. Any help is highly appreciated! Thanks in advance.</p>
  
  <p>Note: Basically, I'm having the same problem stated in <a href="https://stackoverflow.com/questions/5349307/unable-to-show-anything-on-x-axis-and-y-axis-labels-in-core-plot">this SO question</a>, but removing/adding CorePlot from/to the project doesn't solve my problem.</p>
  
  <p><strong>Edit:</strong> I used the latest version from the repository. Changing to 1.0 (the download), it works like a charm.</p>
  
  <pre><code>CPTXYGraph *graph = [[CPTXYGraph alloc] initWithFrame:CGRectZero];
  graphHostingView.collapsesLayers = NO; 
  graphHostingView.hostedGraph     = graph;
  
  graph.paddingLeft   = 10.0;
  graph.paddingTop    = 10.0;
  graph.paddingRight  = 10.0;
  graph.paddingBottom = 10.0;
  
  CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *)graph.defaultPlotSpace;
  plotSpace.allowsUserInteraction = YES;
  plotSpace.xRange                = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(0.0) length:CPTDecimalFromFloat(500.0)];
  plotSpace.yRange                = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(0.0) length:CPTDecimalFromFloat(40.0)];
  
  CPTXYAxisSet *axisSet = (CPTXYAxisSet *)graph.axisSet;    
  CPTXYAxis *x          = axisSet.xAxis;
  x.title = @"Date";
  x.majorIntervalLength         = CPTDecimalFromString(@"280");
  x.orthogonalCoordinateDecimal = CPTDecimalFromString(@"0");
  x.minorTicksPerInterval       = 4;    
  
  CPTXYAxis *y = axisSet.yAxis;
  y.title = @"Temperature";
  y.majorIntervalLength         = CPTDecimalFromString(@"10");
  y.orthogonalCoordinateDecimal = CPTDecimalFromString(@"0");
  y.minorTicksPerInterval       = 2;    
  
  CPTScatterPlot *temperaturePlot  = [[CPTScatterPlot alloc] init];
  temperaturePlot.interpolation = CPTScatterPlotInterpolationCurved;
  temperaturePlot.dataSource    = self;
  
  [graph addPlot:temperaturePlot];
  </code></pre>
  
  <p><strong>Edit</strong>: Adding padding to the plotArea does not help, as seen in the screenshots below.
