How to change the XAxis used on my chart ShinobiCharts - iphone

Question

I'd like to have the xAxis of my chart to look like this :
Jan, Feb, Mar, Apr, ..... Nov, Dec
Right now it's following it's default, numbering xAxis according to the number of Data Points.
How can i achieve this change to this axis ?
I've tried using Category Axis and setting an NSMutableArray containing these strings ("Jan", "Feb"...) as categories and with a numberRange going from 1 to 12 but it didn't work.
chart = [[ShinobiChart alloc] initWithFrame:chartEmbaixo.frame withPrimaryXAxisType:SChartAxisTypeCategory withPrimaryYAxisType:SChartAxisTypeNumber];
NSMutableArray * monthNames = [[NSMutableArray alloc] initWithObjects:#"Jan", #"Fev", #"Mar", #"Abr", #"Mai", #"Jun", #"Jul", #"Ago", #"Set", #"Out", #"Nov", #"Dez", nil];
SChartNumberRange * numberRange = [[SChartNumberRange alloc] initWithMinimum:[NSNumber numberWithInt:1]andMaximum:[NSNumber numberWithInt:12]];
SChartCategoryAxis *xAxis = [[SChartCategoryAxis alloc] initWithRange:numberRange];
xAxis.categories = monthNames;
chart.xAxis = xAxis;

Answer 1

first i use as my x axis
Edit how i make my x axis:
SChartNumberRange *r1 = [[SChartNumberRange alloc] initWithMinimum:[NSNumber numberWithInt:0] andMaximum:[NSNumber numberWithInt:2]];
SChartCategoryAxis *xAxis = [[SChartCategoryAxis alloc] initWithRange:r1];
xAxis.title = #"";
//xAxis.enableGesturePanning = YES;
xAxis.enableGesturePanning = YES;
xAxis.style.gridStripeStyle.showGridStripes = NO;
xAxis.style.majorGridLineStyle.showMajorGridLines = NO;
when you make you data points it should use the xValue as the x axis point.
like this:
dp.yValue = 1000;
dp.xValue = #"Jan";
the xValue should be set as the x point for that particular data point. This should work, but if it doesn't or you want to do something more complex you can extend this method from SChartDelegate protocol:
-(void)sChart:(ShinobiChart *)chart alterTickMark:(SChartTickMark *)tickMark beforeAddingToAxis:(SChartAxis *)axis
in this method you have the tickMark.tickLabelis the axis label for that given point where you can do your editing. Don't forget to verify what axis your on.
Hope this helps. If not tomorrow i can post you some code from my project (currently i don't have access to it from where i am)
Edit: currently i have this code:
- (void)sChart:(ShinobiChart *)chart alterTickMark:(SChartTickMark *)tickMark beforeAddingToAxis:(SChartAxis *)axis {
if (chart.yAxis == axis ) return;
for (UIView *i in tickMark.tickMarkView.subviews)
[i removeFromSuperview];
tickMark.tickMarkView.frame = CGRectMake(0, 0, 170, 75);
//center the marker at the right place because the size was changed
tickMark.tickMarkX = tickMark.tickMarkX - (tickMark.tickMarkView.frame.size.width/2) ;
tickMark.tickMarkY = 10;
//img
UIImageView *img = [[UIImageView alloc] initWithImage:[UIImage imageNamed: #"graph_bar_tag_2#2x.png"]];
img.frame = CGRectMake( 0, 0, tickMark.tickMarkView.frame.size.width, tickMark.tickMarkView.frame.size.height);
[tickMark.tickMarkView addSubview:img];
//label with the markView's size with 7px padding on the left and on the right
UILabel *label = [[UILabel alloc] initWithFrame: CGRectMake( 7, 5, tickMark.tickMarkView.frame.size.width-14, 15)];
label.backgroundColor = [UIColor clearColor];
//tikMark.tickLabel has an pair of indexes so that i can easily find the data for this particular data point and series.
label.text = [_dataSource getNameFor: tickMark.tickLabel.text];
label.textAlignment = UITextAlignmentCenter;
//color_other_light is a UIColor var
[label setTextColor: color_other_light];
[tickMark.tickMarkView addSubview:label];
...
}
