core-plot barchart does not work!!
- by user355068
Hello~
I try to draw bar chart!!
numberForPlot is not good work, only CPBarPlotFieldBarLength set.
-(NSNumber *)numberForPlot: (CPPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index {
NSDecimalNumber *num = nil;
NSString *key = (fieldEnum == CPScatterPlotFieldX) ? @"x" : @"y";
if ( [plot isKindOfClass:[CPBarPlot class]] ) {
switch ( fieldEnum ) {
NSLog(@"fieldEnum = %d",fieldEnum);
case CPBarPlotFieldBarLocation:
num = (NSDecimalNumber *)[NSDecimalNumber numberWithUnsignedInteger:index];
NSLog(@"CPBarPlotFieldBarLocation return num = %@",num);
break;
case CPBarPlotFieldBarLength:
num = (NSDecimalNumber *)[NSDecimalNumber numberWithUnsignedInteger: (index+1)*(index+1)];
if ( [plot.identifier isEqual:Plot3Identity] )
num = [[self.ExForPlot objectAtIndex:index] valueForKey:key];
NSLog(@"CPBarPlotFieldBarLength return num = %@",num);
break;
}
}
else {
NSLog(@"...??..");
}
return num;
}
