    <p>I have attached a screenshot of my graph. </p> <p><img src="https://i.stack.imgur.com/d8Yxg.png" alt="core-plot"></p> <p>I need to fix the following issues.</p> <p>1) This graph starts at 60. So I no longer need that 0-60 y axis line under the x axis. How to remove that part? Y axis should start from 60 and go upwards.</p> <p>2) How to add the tick for x axis. Since my labels are inclined I need to add it properly. </p> <p>Here is my code</p> <pre><code> // Create graph from theme graph = [[CPTXYGraph alloc] initWithFrame:CGRectZero]; CPTTheme *theme = [CPTTheme themeNamed:kCPTDarkGradientTheme]; [graph applyTheme:theme]; CPTGraphHostingView *hostingView = (CPTGraphHostingView *)self.view; hostingView.collapsesLayers = NO; // Setting to YES reduces GPU memory usage, but can slow drawing/scrolling hostingView.hostedGraph = graph; graph.paddingLeft = 10.0; graph.paddingTop = 10.0; graph.paddingRight = 10.0; graph.paddingBottom = 10.0; // Setup plot space CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *)graph.defaultPlotSpace; plotSpace.allowsUserInteraction = YES; plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(-100.0) length:CPTDecimalFromFloat(500.0)]; plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(-2.25) length:CPTDecimalFromFloat(15.0)]; CPTMutableLineStyle *xLineStyle = [CPTMutableLineStyle lineStyle]; xLineStyle.miterLimit = 1.0f; xLineStyle.lineWidth = 3.0f; xLineStyle.lineColor = [CPTColor whiteColor]; // Axes CPTXYAxisSet *axisSet = (CPTXYAxisSet *)graph.axisSet; CPTXYAxis *x = axisSet.xAxis; x.visibleRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(0) length:CPTDecimalFromFloat(100)]; x.majorIntervalLength = CPTDecimalFromString(@"1"); x.orthogonalCoordinateDecimal = CPTDecimalFromDouble(60.0); x.titleLocation = CPTDecimalFromFloat(0.5f); x.titleOffset = 5.0f; x.labelingPolicy = CPTAxisLabelingPolicyNone; NSMutableArray *customTickLocations = [[NSMutableArray alloc] init]; if (selectedIndex == 0) { self.xAxisLabels = [[[NSMutableArray alloc] init] autorelease]; for (int i = 0; i &lt; [items count]; i++) { WeightDTO *weightDTO = [items objectAtIndex:i]; [xAxisLabels addObject:weightDTO.dateAdded]; [customTickLocations addObject:[NSString stringWithFormat:@"%d", i]]; } } NSUInteger labelLocation = 0; NSMutableArray *customLabels = [NSMutableArray arrayWithCapacity:[xAxisLabels count]]; for ( NSNumber *tickLocation in customTickLocations ) { CPTAxisLabel *newLabel = [[CPTAxisLabel alloc] initWithText:[xAxisLabels objectAtIndex:labelLocation++] textStyle:x.labelTextStyle]; newLabel.tickLocation = [tickLocation decimalValue]; newLabel.offset = x.labelOffset + x.majorTickLength; newLabel.rotation = M_PI / 4; [customLabels addObject:newLabel]; [newLabel release]; } x.axisLabels = [NSSet setWithArray:customLabels]; CPTXYAxis *y = axisSet.yAxis; y.visibleRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromFloat(0) length:CPTDecimalFromFloat(500)]; y.majorIntervalLength = CPTDecimalFromString(@"30"); y.minorTicksPerInterval = 5; y.orthogonalCoordinateDecimal = CPTDecimalFromDouble(0.0); y.delegate = self; // Create a blue plot area CPTScatterPlot *boundLinePlot = [[[CPTScatterPlot alloc] init] autorelease]; CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; lineStyle.miterLimit = 1.0f; lineStyle.lineWidth = 3.0f; lineStyle.lineColor = [CPTColor redColor]; boundLinePlot.dataLineStyle = lineStyle; boundLinePlot.identifier = @"Blue Plot"; boundLinePlot.dataSource = self; [graph addPlot:boundLinePlot]; // Do a blue gradient CPTColor *areaColor1 = [CPTColor colorWithComponentRed:0.3 green:0.3 blue:1.0 alpha:0.8]; CPTGradient *areaGradient1 = [CPTGradient gradientWithBeginningColor:areaColor1 endingColor:[CPTColor clearColor]]; areaGradient1.angle = -90.0f; boundLinePlot.areaBaseValue = [[NSDecimalNumber zero] decimalValue]; // Add plot symbols CPTMutableLineStyle *symbolLineStyle = [CPTMutableLineStyle lineStyle]; symbolLineStyle.lineColor = [CPTColor blackColor]; CPTPlotSymbol *plotSymbol = [CPTPlotSymbol ellipsePlotSymbol]; plotSymbol.fill = [CPTFill fillWithColor:[CPTColor blueColor]]; plotSymbol.lineStyle = symbolLineStyle; plotSymbol.size = CGSizeMake(10.0, 10.0); boundLinePlot.plotSymbol = plotSymbol; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
