    <p>I'm reading a <code>.CSV</code> file on a server using <code>NSMutableURLRequest</code> and when I did CSV parsing of the data, I end up reading the plot points incomplete. For example if i have 300 plus rows the app reads it from 150th plus row. Any suggestion on how to approach this? Is there a function that stores the value of the plot points? Sorry I'm new to iOS. Thanks much for the help</p> <pre><code> - (id) init { // regular [super init], etc. etc. NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(_connectionTimer:) userInfo:nil repeats:YES]; // other custom initialization continues return self; } -(void)serverConnect{ NSMutableURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"URL/test.csv"] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:15.0]; NSURLConnection *connection= [[NSURLConnection alloc] initWithRequest:request delegate:self]; } - (void) _connectionTimer:(NSTimer *)timer { [self serverConnect]; } -(void)connection :(NSURLConnection *) connection didReceiveData:(NSData *)data{ response = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSString *stripped1 = [response stringByReplacingOccurrencesOfString:@"\r" withString:@""]; NSMutableArray *rows = [NSMutableArray arrayWithArray:[stripped1 componentsSeparatedByString:@"\n"]]; NSMutableArray *contentArray = [NSMutableArray arrayWithCapacity:[rows count]]; NSMutableArray *contentArray1 = [NSMutableArray arrayWithCapacity:[rows count]]; NSArray *components; for (int i=0;i&lt;[rows count]; i++) { if(i == 0 || [[rows objectAtIndex:i] isEqualToString:@""]){ continue; } components = [[rows objectAtIndex:i] componentsSeparatedByString:@","]; id x = [components objectAtIndex:0] ; id y = [components objectAtIndex:1]; id z = [components objectAtIndex:2]; [contentArray addObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:x,@"X",y,@"Y", nil]]; [contentArray1 addObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:x,@"X",z,@"Y", nil]]; } } - (void)viewDidLoad { [super viewDidLoad]; [_graphHostingView setContentSize:CGSizeMake(2000, 1000)]; _graphHostingView.scrollEnabled = YES; _graphHostingView.showsHorizontalScrollIndicator = YES; _graphHostingView.showsVerticalScrollIndicator = YES; [self init]; //[self serverConnect]; } </code></pre> <p>variable response is <code>NSString</code>. Will it be better if i use <code>MSMutableString</code> or <code>NSMutableArray</code> ? If not can anyone explain how <code>-(NSArray *)numbersForPlot:(CPPlot *)plot field:(NSUInteger)fieldEnum recordIndexRange:(NSRange)indexRange;</code> method helps? Does it help me save the plot data ? So next can I just load it when the core plot is used to plot? Is the use of timer affecting the data that is being read?</p>

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.
