Because the range of the plot doesn't include the coordinates for the line. The line will appear at x = e^4 which is greater than 10. You can see this is the case by doing: LogLinearPlot[x, {x, 1, 60}, Epilog -> Line[{{4, 0}, {4, 10}}]] You can get the desired result by doing: LogLinearPlot[x, {x, 1, 10}, Epilog -> Line[{{Log@4, 0}, {Log@4, 10}}]] And since you are drawing a vertical line across the entire plot an alternative would be: LogLinearPlot[x, {x, 1, 10}, GridLines -> {{4}, None}]
