X/Y Axis Title

[Jon]

I'm attempting to set the x/y axis titles.  I'm using the following code:


    TKChartSeries *series = [[TKChartBarSeries alloc] initWithItems:array];
    //series.style.paletteMode = TKChartSeriesStylePaletteModeUseItemIndex;
    series.selectionMode = TKChartSeriesSelectionModeNone;

    [[series xAxis] setTitle:@"X Axis Name"];
    [[series yAxis] setTitle:@"Y Axis Name"];

However, nothing is being display at run time.  What am I leaving out?


Cheers, Jon

Hi Jon,

Thank you for evaluating our product.

By default xAxis and yAxis properties are empty, they are assigned to valid values after the series object is added to a chart instance. For example:

TKChartSeries *series = [[TKChartBarSeries alloc] initWithItems:array];
series.selectionMode = TKChartSeriesSelectionModeNone;

[_chart addSeries:series];

[[series xAxis] setTitle:@"X Axis Name"];
[[series yAxis] setTitle:@"Y Axis Name"];

Another option would be to create the axis instance manually:

TKChartSeries *series = [[TKChartBarSeries alloc] initWithItems:array];
series.selectionMode = TKChartSeriesSelectionModeNone;

TKChartNumericAxis *xAxis = [[TKChartNumericAxis alloc] initWithMinimum:@0 andMaximum:@2000];
xAxis.position = TKChartAxisPositionBottom;
xAxis.majorTickInterval = @300;
series.xAxis = xAxis;
[_chart addAxis:xAxis];

TKChartNumericAxis *yAxis = [[TKChartNumericAxis alloc] initWithMinimum:@0 andMaximum:@12];
yAxis.position = TKChartAxisPositionLeft;
yAxis.majorTickInterval = @1;
series.yAxis = yAxis;
[_chart addAxis:yAxis];

[[series xAxis] setTitle:@"X Axis Name"];
[[series yAxis] setTitle:@"Y Axis Name"];

[_chart addSeries:series];
