chart_Series() 是否适用于对数轴? [英] Does chart_Series() work with logarithmic axis?

问题描述

有没有办法用 chart_Series() 生成对数 y 轴?我在 quantmod 中使用实验性的 chart_Series() 而不是 chartSeries() 方法，因为在向情节.

Is there a way to produce logarithmic y-axis with chart_Series()? I am using the experimental chart_Series() rather than the chartSeries() method in quantmod, because it is more convenient when adding additional lines to the plot.

library(quantmod)
POWR <- getSymbols("POWR", auto.assign=FALSE)

# the following attempts did not produce logarithmic axis for y
chart_Series(POWR, log.scale=TRUE)  # like in chartSeries()
chart_Series(POWR, log="y")         # like in plot.default()

快速查看代码，似乎也无法使用现有的 chart_pars() 或 chart_theme() 方法进行自定义.

From a quick look into the code, it does not seem to be possible using existing chart_pars() or chart_theme() methods for customization, too.

非常感谢您的帮助.

推荐答案

如果您不需要 OHLC 图表并且关闭是您所需要的全部，您可以使用 chart.TimeSeries 函数从PerformanceAnalytics" - 包，您可以在其中使用多种选项来自定义图表.

If you don't need an OHLC chart and the Close is all you need you can use the chart.TimeSeriesfunction from the 'PerformanceAnalytics' - package, where you have lots of options to customize the chart.

chart.TimeSeries(cumprod(1+ ROC(POWR, type = "discrete")[-1,6]),ylog = TRUE,minor.ticks =FALSE)
