在我的圖表中,majorGridLines對整個數字都能正常工作,但是當範圍介於3.0和0.0之間時,10個或更多的majorTickLocations。 tick位置在正確的位置,IE大約每0.3,但主要的GridLines與Tick不在同一位置,它們只落在整個數字1.0,2.0,3.0等。我怎樣才能讓majorGridLines工作與不完整的數字,並與tickLocations水平?核心圖Y軸majorgridline只能落在整數上?
代碼如下:
NSMutableSet *yLabels = [NSMutableSet set];
NSMutableSet *yMajorLocations = [NSMutableSet set];
for (int i=-1; i<numYAxisLabels; i++) {
id jAsID = [NSNumber numberWithInt:(int)j];
int jAsInt = [jAsID integerValue];
CPTAxisLabel *label;
if(majorIncrement < 1)
label = [[CPTAxisLabel alloc] initWithText:[NSString stringWithFormat:@"%.1f", j] textStyle:y.labelTextStyle];
else
label = [[CPTAxisLabel alloc] initWithText:[NSString stringWithFormat:@"%d", jAsInt] textStyle:y.labelTextStyle];
NSDecimal location = CPTDecimalFromFloat(j);
label.tickLocation = location;
label.offset = -y.majorTickLength - y.labelOffset;
[yLabels addObject:label];
[yMajorLocations addObject:jAsID];
currTopYLabelLocation = j;
j += majorIncrement;
}
y.axisLabels = yLabels;
y.majorTickLocations = yMajorLocations;
謝謝Eric,就是這樣!我的道歉,我認爲情況並非如此,因爲tickLocations出現的很好。 – Baconbeastnz 2013-02-25 01:48:49
