问题描述
很长一段时间以来,我一直遇到这个问题,我找不到任何解决方法.我读了几个论坛,但找不到有效的解决方案.我有以下代码:
I have this problem since a long time and I cannot find anything to solve this. I read several forum but was not able to find a working solution. I have the following code:
// Adjust graph using above data
CPXYPlotSpace *plotSpace = (CPXYPlotSpace *)graph.defaultPlotSpace;
plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(-10) length:CPDecimalFromFloat(xmax + 17)];
plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(-450) length:CPDecimalFromFloat(3750)];
// Setup axis
CPXYAxisSet *axisSet = (CPXYAxisSet *)graph.axisSet;
CPLineStyle *lineStyle = [CPLineStyle lineStyle];
lineStyle.lineColor = [CPColor whiteColor];
lineStyle.lineWidth = 1.0f;
CPTextStyle *cyanStyle = [CPTextStyle textStyle];
cyanStyle.color = [CPColor cyanColor];
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setMaximumFractionDigits:0];
// x axis with custom labels
axisSet.xAxis.labelingPolicy = CPAxisLabelingPolicyNone;
axisSet.xAxis.majorTickLineStyle = lineStyle;
axisSet.xAxis.axisLineStyle = lineStyle;
axisSet.xAxis.majorTickLength = 3.0f;
axisSet.xAxis.labelOffset = 3.0f;
axisSet.xAxis.visibleRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromInteger(0) length:CPDecimalFromInteger(xmax)];
axisSet.xAxis.labelExclusionRanges = [NSArray arrayWithObjects:
[CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(-10)
length:CPDecimalFromFloat(10)],
nil];
NSArray *customTickLocations = [NSArray arrayWithObjects:[NSDecimalNumber numberWithInt:0],
[NSDecimalNumber numberWithInt:6],
[NSDecimalNumber numberWithInt:12],
[NSDecimalNumber numberWithInt:18],
[NSDecimalNumber numberWithInt:24],
[NSDecimalNumber numberWithInt:30],
[NSDecimalNumber numberWithInt:36],
[NSDecimalNumber numberWithInt:41],
[NSDecimalNumber numberWithInt:47],
nil];
// This return the labels (11h, 14h, ..., 22h, ..)
NSArray *xAxisLabels = [GPHelpers getHoursList:fromStr to:toStr];
NSUInteger labelLocation = 0;
NSMutableArray *customLabels = [NSMutableArray arrayWithCapacity:[xAxisLabels count]];
for (NSNumber *tickLocation in customTickLocations) {
CPAxisLabel *newLabel = [[CPAxisLabel alloc] initWithText: [xAxisLabels objectAtIndex:labelLocation++] textStyle:axisSet.xAxis.labelTextStyle];
newLabel.tickLocation = [tickLocation decimalValue];
//newLabel.majorTickLocations = [tickLocation decimalValue];
newLabel.offset = axisSet.xAxis.labelOffset + axisSet.xAxis.majorTickLength;
[customLabels addObject:newLabel];
[newLabel release];
}
axisSet.xAxis.axisLabels = [NSSet setWithArray:customLabels];
我看到x上的标签,但完全没有刻度.
I see the labels but no ticks at all on x.
推荐答案
为结束这个问题,我得到了其中一位核心人物的回答:
Just to close this question, I had an answer from one of the core-plot guys:
只需设置刻度位置,添加以下语句即可:
Just need to set the tick locations, adding this statement:
axisSet.xAxis.majorTickLocations = [NSSet setWithArray:customTickLocations];
