All graph points are overlapping

[GoogleCodeExporter]

I am creating a scattergraph.But my points are overlapping.I am using the 
following code.

-(void)configureGraph {
    // 1 - Create the graph
    CPTGraph *graph = [[CPTXYGraph alloc] initWithFrame:self.hostView.bounds];
    [graph applyTheme:[CPTTheme themeNamed:kCPTDarkGradientTheme]];
    self.hostView.hostedGraph = graph;
    // 2 - Set graph title
    NSString *title = @"License Graph";
    graph.title = title;
    // 3 - Create and set text style
    CPTMutableTextStyle *titleStyle = [CPTMutableTextStyle textStyle];
    titleStyle.color = [CPTColor whiteColor];
    titleStyle.fontName = @"Helvetica-Bold";
    titleStyle.fontSize = 16.0f;
    graph.titleTextStyle = titleStyle;
    graph.titlePlotAreaFrameAnchor = CPTRectAnchorTop;
    graph.titleDisplacement = CGPointMake(0.0f, 10.0f);
    // 4 - Set padding for plot area
    [graph.plotAreaFrame setPaddingLeft:30.0f];
    [graph.plotAreaFrame setPaddingBottom:30.0f];
    // 5 - Enable user interactions for plot space
    CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *) graph.defaultPlotSpace;
    plotSpace.allowsUserInteraction = YES;
}

-(void)configurePlots {
    // 1 - Get graph and plot space
    CPTGraph *graph = self.hostView.hostedGraph;
    CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *) graph.defaultPlotSpace;
    // 2 - Create the three plots

All three plots are getting the same data from the datasource. Use the plot 
parameter to the datasource methods to determine which plot is requesting 
information. Plots have an identifier property that you can use to distinguish 
them easily.

Please tell me how to make some space between the different points so that they 
exactly match the x-label(which are dates).Currently there is no space between 
diferent data points.

Lets take this conversation to the Core Plot discussion board where more people 
are likely to find it.
