How to integrate DateLispPlot and TimeLinePlot correctly?

I need to integrate DateLispPlot with TimeLinePlotLinePlot. Try to use Show instruction, but although the graphs overlap, the time axis (X-axis), GridLines and DateTicks cannot be properly aligned. Is there a correct way? ClearAll["Global`*"] ts = DateListPlot[ CountryData[#, {"Population", {1900, 2000}}] &@"United States", GridLines -> Automatic]; ww = TimelinePlot[{Entity["HistoricalEvent", "WorldWar1"], Entity["HistoricalEvent", "WorldWar2"], Entity["HistoricalEvent", "VietnamWar"], Entity["HistoricalEvent", "KoreanWarBegins"]}, GridLines -> Automatic]; Show[{ts, ww}]

You just need to adjust your spacings because when you combine the plots, it uses the scaling from the y axis of the population plot: ts = DateListPlot[ CountryData[#, {"Population", {1900, 2000}}] &@"United States", GridLines -> Automatic]; ww = TimelinePlot[{Entity["HistoricalEvent", "WorldWar1"], Entity["HistoricalEvent", "WorldWar2"], Entity["HistoricalEvent", "VietnamWar"], Entity["HistoricalEvent", "KoreanWarBegins"]}, GridLines -> Automatic, Spacings -> {2*^7}]; Show[ts, ww, ImageSize -> Large] to get Regards, Neil
