/**
 * Provides an implementation of Numeric {@link CoordinateCalculatorBase | Coordinate Calculator} which transforms
 * numeric data-values to pixel coordinates using logarithmic scaling and vice versa.
 * @remarks
 * SciChart's {@link https://www.scichart.com/javascript-chart-features | JavaScript Charts} perform conversion operations between
 * data-coordinates for all drawing and axis measurements.
 *
 * You can fetch a CoordinateCalculator instance by calling {@link AxisCore.getCurrentCoordinateCalculator}. This will return a unique calculator
 * for the current draw pass.
 *
 * You can convert pixel to data-coordinates and back by using the following code:
 * ```ts
 * const axis: AxisCore;
 * const calc = axis.getCurrentCoordinateCalculator();
 *
 * const pixel = calc.getCoordinate(1.23); // Gets the pixel coordinate for data-value 1.23
 * const dataValue = cald.getDataValue(pixel); // Performs the inverse operation to get data-value
 * ```
 *
 * Use the Coordinate calculators when drawing, placing markers, annotations or if you want to place a tooltip over the chart.
