API Reference
ChartXProjection
A detached linear X projection captured from a prepared Line or StepLine chart.
Inheritance
- Object
- ChartXProjection
Remarks
Bounds include resolved authored limits and automatic full-chart marker padding. A requested viewport retains those full bounds while using its exact window for mapping and clipping. This snapshot does not retain the chart, its axes, or formatter callbacks.

Methods
public ChartXViewport? ConstrainViewport(Double firstLogicalX, Double secondLogicalX) #ChartXViewport?Converts a logical gesture into an increasing X window contained in the captured full domain.
Parameters
- firstLogicalX System.Double
- The first logical X position, including positions outside the plot.
- secondLogicalX System.Double
- The second logical X position, including positions outside the plot.
Returns
The confined window, or null when the requested span covers the full domain and preparation should reset.
Exceptions
ArgumentOutOfRangeException– A position or mapped bound is not finite, or the requested span is empty or cannot be represented at the confined bounds.
public Double Project(Double sourceX) #DoubleMaps a finite source X coordinate into logical scene units.
Parameters
- sourceX System.Double
- A source coordinate, including coordinates outside the current window.
Returns
The mapped coordinate; values outside the window extrapolate beyond the plot.
Exceptions
ArgumentOutOfRangeException– The input or extrapolated result is not finite.
public Double Unproject(Double logicalX) #DoubleMaps a finite logical X coordinate back into source coordinates.
Parameters
- logicalX System.Double
- A logical coordinate, including coordinates outside the plot.
Returns
The source coordinate; values outside the plot extrapolate beyond the current window.
Exceptions
ArgumentOutOfRangeException– The input or extrapolated result is not finite.
