Learn Color Gradients with scale_fill_gradient2 in R

KeyPoints scale_fill_gradient2 is a function in the ggplot2 package that creates a diverging color gradient for fill aesthetics. fill aesthetic is an aesthetic that controls the color of the interior of a geometric object, such as a bar, a point, or a polygon. diverging color gradient is a color gradient with three colors: one for low values, one for high values, and one for middle values. The colors usually diverge from the middle value, often white or gray. scale_fill_gradient2 has several arguments that can customise the colors, midpoint, space, and gradient guide, such as low, high, mid, midpoint, space, na.value, guide, and aesthetics. scale_fill_gradient2 can be applied to different types of plots, such as bar charts, histograms, and scatter plots , by using different geoms and aesthetics, such as geom_bar, geom_histogram, geom_point, x, y, and fill. scale_fill_gradient2 can be used with other aesthetics, such as alpha, size, and shape, to add more dimensions and information to the plo…
