title: Core Plot: RealTimePlot - put static yAxis
body: <p>My problem is that i cant put static yAxis (without movement) in my example of RealTimePlot. 
  During movement xAxis are static but yAxis disappear.</p>
  
  <p>My code is:</p>
  
  <pre><code>-(void)renderInLayer:(CPTGraphHostingView *)layerHostingView withTheme:(CPTTheme *)theme
  {
  
      graph = [[[CPTXYGraph alloc] initWithFrame:bounds] autorelease];
      layerHostingView.hostedGraph = graph;
  
      graph.plotAreaFrame.paddingTop    = 15.0;
      graph.plotAreaFrame.paddingRight  = 15.0;
      graph.plotAreaFrame.paddingBottom = 55.0;
      graph.plotAreaFrame.paddingLeft   = 55.0;
  
      // Axes
      // X axis
      CPTXYAxisSet *axisSet = (CPTXYAxisSet *)graph.axisSet;
      CPTXYAxis *x          = axisSet.xAxis;
      x.labelingPolicy              = CPTAxisLabelingPolicyAutomatic;
      x.orthogonalCoordinateDecimal = CPTDecimalFromUnsignedInteger(0);
      x.minorTicksPerInterval       = 9;
      x.title                       = @"X Axis";
      x.titleOffset                 = 35.0;
  
      // Y axis
      CPTXYAxis *y = axisSet.yAxis;
      y.labelingPolicy              = CPTAxisLabelingPolicyAutomatic;
      y.orthogonalCoordinateDecimal = CPTDecimalFromUnsignedInteger(0);
      y.minorTicksPerInterval       = 3;
      y.labelOffset                 = 5.0;
      y.title                       = @"Y Axis";
      y.titleOffset                 = 30.0;
  
      y.constraints = CPTMakeConstraints(CPTConstraintNone, CPTConstraintFixed);
  
      // Rotate the labels by 45 degrees, just to show it can be done.
      x.labelRotation = M_PI * 0.25;
  
      // Create the plot
      CPTScatterPlot *dataSourceLinePlot = [[[CPTScatterPlot alloc] init] autorelease];
      dataSourceLinePlot.identifier     = kPlotIdentifier;
      dataSourceLinePlot.cachePrecision = CPTPlotCachePrecisionDouble;
  
      CPTMutableLineStyle *lineStyle = [[dataSourceLinePlot.dataLineStyle mutableCopy] autorelease];
      lineStyle.lineWidth              = 3.0;
      lineStyle.lineColor              = [CPTColor greenColor];
      dataSourceLinePlot.dataLineStyle = lineStyle;
  
      dataSourceLinePlot.dataSource = self;
      [graph addPlot:dataSourceLinePlot];
  </code></pre>
  
  <p>}</p>
  
  <p>My version of CorePlot is 1.0.</p>
  
  <p>Any idea??</p>
