Overview

The NChartAxisPositionCoord class provides methods to control the position of the chart axis. Each Cartesian system axis has properties for X, Y and Z coordinates, but for every particular axis only two of them are meaningful. For example, for the X-Axis only Y and Z take effect, for Y-Axis only X and Z and so on. Each coordinate is associated with particular direction: X-coordinate is tied to the horizontal direction, Y to the vertical and Z to the depth. According to valueType, value and hostsOnSAxis of the coordinate, actual position in the corresponding direction is determined.
For example, to place Y-Axis so, that it intersects X-Axis in the value 10, use the following code:
m_view.chart.cartesianSystem.yAxis.positionX.value = 10.0;
If you need Y-Axis to intersect SX-Axis in the value 10 instead, add the following:
m_view.chart.cartesianSystem.yAxis.positionX.hostsOnSAxis = YES;
The next code line added to the previous settings will make Y-Axis to intersect SX-Axis in its maximal value:
m_view.chart.cartesianSystem.yAxis.positionX.valueType = NChartAxisPositionCoordValueMaximum;
