我正在创建图表,想要更改标题和副标题的字体。
我希望标题为Futura粗体,而副标题为Futura Plain。
# Get the mtcars dataset to create some example plots
data(mtcars)
df <- mtcars[, c("mpg", "cyl", "wt")]
# Convert cyl to a factor variable
df$cyl <- as.factor(df$cyl)
# Plot
ggplot(data = mtcars, aes(x = wt, y = mpg)) +
geom_point() +
ggtitle('Basic Scatter Chart', subtitle = 'New ggplot theme') +
theme(
# Set title
plot.title = ggplot2::element_text(family='Futura',
size=20,
face='bold',
color="#222222"),
plot.subtitle = ggplot2::element_text(family= 'Futura',
face='plain',
size=16,
margin=ggplot2::margin(9,0,9,0)))
这给了我以下错误:
Error in grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
polygon edge not found
In addition: Warning messages:
1: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
no font could be found for family "Futura"
2: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, :
no font could be found for family "Futura"
如果我将face参数从Plain更改为粗体,则该绘图有效,因此似乎R找不到Futura字体的Plain变体。当我查看字体书时,可以看到中等,中等斜体,粗体。
对于其他与正面兼容的字体(例如Helvetica),它们在字体簿中有一个常规变体。
如何纠正此问题以使Futura的普通变体正常工作?我不仅可以在R中将媒体分配给普通吗?
