绘制图例并获取：strwidth错误（图例，单位=“用户”，cex = cex，font = text.font）：plot.new尚未调用

Question

I've created multiple time series in rStudio. And I am attempting to plot it using ts.plot() . The plot works fine but adding a legend causes issues and gives :

Error in strwidth(legend, units = "user", cex = cex, font = text.font) : plot.new has not been called yet.

I have tried running all the code at once and adjusting the parameters.

ts.plot(nltnr.ts, peitnr.ts, nstnr.ts, nbtnr.ts, qbtnr.ts, ontnr.ts, mbtnr.ts, sktnr.ts, abtnr.ts, bctnr.ts, yktnr.ts, nttnr.ts, nvtnr.ts,
        gpars = list(
        ylab = "Amount in millions",
        col=1:12,
        legend("bottom", legend = 1:12)
        ))

Answer 1

ts.plot(nltnr.ts, peitnr.ts, nstnr.ts, nbtnr.ts, qbtnr.ts, ontnr.ts, mbtnr.ts, sktnr.ts, abtnr.ts, bctnr.ts, yktnr.ts, nttnr.ts, nvtnr.ts,
        gpars = list(
        ylab = "Amount in millions",
        col=1:12))
        legend("bottom", legend = 1:12)

Try running the legend() command after doing your plot, and not while running your plot.
