无法更新x，y轴和主图区域的标签

Question

I am trying to plot a time series graph but the labels of the xaxis, yaxis and the main area won't change. What I can do right in the following code?How do I set the max and min value of the y-axis?

plot(gfit.acc1, which = 3, type ="l", col= "lightblue", 
   xlab= "3 * GARCHSTD, SP RETURNS, -3 * GARCHSTD" , main ="GARCH volatilities")

Answer 1

To set the max and min value or x-axis or y-axis , use xlim and ylim in plot.window .

Adding to your code,

plot(gfit.acc1, which = 3, type ="l", col= "lightblue", 
   xlab= "3 * GARCHSTD, SP RETURNS, -3 * GARCHSTD" , main ="GARCH volatilities"
   plot.window(xlim=c(low, high), ylim=c(high,low)))

For more information, check ?plot and ?plot.window

PS: Answered this question with the understanding that, you need to know how to set up min and max values for axes.
