In Nevron NOV Chart for .NET, axes define how data point values are mapped to a coordinate system dimension within the chart. Each axis transforms a single data value to a specific model coordinate along the axis dimension. Depending on the type of chart or gauge, one, two, or three axes may be required to create a coordinate system that can transform the data point’s logical data values to screen coordinates.
All axes in NOV Chart and NOV Gauge share common functionality that determines their position, scale, and additional attributes such as reference lines, strip lines, and ranges.
The following topics explain the specifics related to the different types of axes, which differ mainly in their position and scrolling behavior—as well as their shared functionality, including the common scale model, ranges, and plot decorations (such as reference lines and strip lines).
