ggplot：geom_point中的颜色，填充和大小

I simply want a scatterplot where each point is scaled by size and fill for different variables. I've read just about everywhere about this and I realize the default shape is hollow (I've changed it to 19, which is solid). I want the color and fill to be the same so each point has 1 color, 1 size, 1 x-y coord rather than the donut look its got going on. The separation of color and fill is frustrating me to no end... Here's the code:

我只想要一个散点图，其中每个点按大小缩放并填充不同的变量。我几乎到处都读过这个，我发现默认的形状是空心的（我把它改成了19，这是实心的）。我希望颜色和填充是相同的，所以每个点有1种颜色，1个尺寸，1 x-y坐标而不是甜甜圈外观。颜色和填充的分离令我感到沮丧，无处不在......以下是代码：

ggplot(data, aes(period,freq))+
 geom_point(shape=19,aes(size=copies,fill=total_len,colour=total_len))+
 scale_fill_gradient(low="blue",high="red")+
 scale_colour_gradient(low="blue",high="red")

I think all you need is

我想你需要的只是

ggplot(data, aes(period, freq, size=copies, color=total_len)) + 
   geom_point() + 
   scale_color_gradient(low="blue", high="red")
