Parameters: values (array_like) -- Alpha values (in the [0, 1] range) that make up the palette. range (array_like) -- Range of aesthetic. Default is to automatically determine the range from the data points. breaks (array_like or callable, optional) -- Major break points. Alternatively, a callable that takes a tuple of limits and
Put this first so the dot is on top of the label. geom_text(data = HELPrct %>% filter(e2b > 20), aes(label = id), size = 10, color = "yellow", hjust = 0.5, vjust = 0.5) + geom_point(na.rm = TRUE, aes(alpha = substance)) + scale_color_manual(values = c("red", "navy")) + # I want red and navy for the colors scale_alpha_manual(

ggplot(data=sdf,aes(x=hours,y=count,group=machine,fill=machine,alpha=machine))+ geom_area(position="dodge")+ scale_fill_manual(values=c("chocolate1","goldenrod","pink"))+ scale_alpha_manual(values=c(0.01, 0.2, .1),guide=F). gives me. enter image description here. which has alpha at 1 in the

Alpha-transparency scales are not tremendously useful, but can be a convenient way to visually down-weight less important observations. scale_alpha is an alias for scale_alpha_continuous since that is the most common use of alpha, and it saves a bit of typing. scale_alpha(, range = c(0.1, 1)) scale_alpha_continuous(,
Create your own discrete scale. This allows you to specify you own set of mappings from levels in the data to aesthetic values. scale_colour_manual(, values) scale_fill_manual(, values) scale_size_manual(, values) scale_shape_manual(, values) scale_linetype_manual(, values) scale_alpha_manual(, values)
30 Mar 2012 geom_bar(aes(alpha = b), fill = 'red', stat = 'identity') + scale_alpha_manual(values = c(0.3, 0.6, 0.9)). Question for the gurus: Why do points get plotted with this code??? qplot(b, a, data = df) + geom_bar(aes(alpha = b), fill = 'red', stat = 'identity') + scale_alpha_manual(values = c(0.3, 0.6, 0.9)).
