Dear all,
I would like to add a legend to a time series plot, but cannot get it done. I have searched the archive about this,
but to no avail ...
I have three sets of time series data stored in a matrix wMat. The following code plots the the data with a legend, but it does not put the time on the x-axis:
matplot(y = wMat, type = "l", ylab = "Allocation", main = "GARCH") legend(1, -0.3, c("Stocks", "Bonds", "Cash"), col = 1:3, lty = 1:3)
The following code puts the time on the x-axis but now the legend does not show up:
wMat = ts(wMat, frequency = 12, start = c(1968, 2)) ts.plot(wMat[,1], wMat[,2], wMat[,3], col = 1:3, lty = 1:3, ylab = "Allocation", main = "GARCH") legend(1, -0.3, c("Stocks", "Bonds", "Cash"), col = 1:3, lty = 1:3)
I guess it is clipped in this case. Use par("usr") after ts.plot() to see what the user coordinates are, and whether (1, -0.3) is a sensible location to place the legend.

Can anybody help with this? If needed, I can send along postscript files of the resulting plots.
I do not subscribe to the list, so please (also) reply directly to me.
Thanks very much, Michael
