Remarks
Provides axes for the Chart control, and is exposed by the AxisX, AxisY, AxisX2 and AxisY2 properties of ChartArea objects.
For all charts (except bar, stacked bar, pie and doughnut) the primary and secondary axes are as follows:
| Axis Type | Description |
|---|---|
| Primary X-Axis | Bottom-horizontal axis. |
| Secondary X-Axis | Top-horizontal axis. |
| Primary Y-Axis | Left-vertical axis. |
| Secondary Y-Axis | Right-vertical axis |
Bar-type charts have their axes rotated 90 degrees clockwise, so the primary X axis for these two chart types is the left-vertical axis.
Note that there can only be one set of axes (two vertical and two horizontal) for each ChartArea object.
The Axis class also has several methods used for converting axis values to absolute pixel coordinates (useful for 2D custom drawing) or relative coordinates (useful for 3D custom drawing). Absolute and relative coordinates can also be converted to axis values.
The following are the most important axis elements that are exposed using the Axis class:
| Axis Element | Description |
|---|---|
| Axis Labels | The labels and their associated properties of an axis. |
| Grid Lines | The major and minor grid lines of an axis. |
| Tick Marks | The major and minor tick marks of an axis. |
| Strip Lines | Strip lines. |
