How I Use scale

I’ve created a plot in ggplot2 and then on top of that plot I have used geom_rect() to visualize (in red) the data points with the lowest 10% of values of z.I think that the problem is in the values from scale_fill_gradientn. Also accepts rlang lambda function . 2022R: adjust scale color gradient in ggplot27.5 and up, but I can’t seem to grasp the rescale() function.The scales scale_colour_continuous() and scale_fill_continuous() are the default colour scales ggplot2 uses when continuous data values are mapped onto the colour or fill aesthetics, respectively. We’ll also use the dplyr package, Create a Basic Plot with the fill aesthetic. I have a need to work in base and I think scales can be used there to create color gradients as well but I’m severely off the mark on how.For fill scales, use scale_fill_xxx() versions instead, where xxx is one of gradient, gradient2, or gradientn.This is a good question. Output 1: Output 2 (different data): The final result is ok but I want that the values of the scale range (size and color) to .Most importantly, if we want to correctly map values beyond the actual values of the variable, you have to use limits. See rescale for a convience function to map an arbitrary range to between 0 and 1.
