Costruttori

RColorScale Scale { get; set; }: The color scale (Viridis).
double Min { get; set; }: The value of the first color (NaN: the least of the data).
double Max { get; set; }: The value of the last color (NaN: the largest of the data).
bool Smooth { get; set; }: Whether the colors are blended between the values (false: squares).
string TitleX { get; set; }: The title of the horizontal axis.
string TitleY { get; set; }: The title of the vertical axis.
string Unit { get; set; }: The unit of the values, on the color bar.
CultureInfo Culture { get; set; }: How the numbers are written (invariant: the point).
string BackgroundKey { get; set; }: The theme resource of the background.
string GridKey { get; set; }: The theme resource of the grid.
string InkKey { get; set; }: The theme resource of the texts and the frame.
double TextSize { get; set; }: The size of the texts.
Rect PlotArea { get; }: The area of the map in the last drawing.
(int, int) Size { get; }: How many rows and columns.

void SetValues(double[,] values, double x0, double x1, double y0, double y1): The values [row, column], the rows from y0 at the bottom to y1 at the top, the columns from x0 to x1 (the edges of the matrix).
(double, double) Limits(): The ends of the scale: Min and Max, or those of the data.
double ValueAt(double x, double y): The value at a point of the plane (NaN outside the matrix).
static Color ColorOf(double t, RColorScale scale): The color of a fraction from 0 to 1 of a scale.
void SavePng(string path, double widthCm = 14, double heightCm = 9, double dpi = 300): Saves the map as PNG, the given centimetres wide and high at the given dpi (RImage).
void Render(DrawingContext ctx): Draws the map, the axes, the color bar and the value under the pointer.
