Hi @Anonymous ,

change line 558-559 to this.

plot(forecast(prediction, lwd=pointCex, col=alpha(pointsCol,transparency), fcol=alpha(forecastCol,transparency), flwd = pointCex, shaded=fillConfidenceLevels,

main = "", sub = pbiInfo, col.sub = infoTextColor, cex.sub = cexSub, xlab = labTime, ylab = labValue, xaxt = "n"))

Hello

I have made the proposed changes at line 558-559 and now it works.

As I am a beginer in R, it will remain me to understand the script.

Thank you very much.
