Label xline stata11/11/2023 ![]() ![]() The tline() option also understands that the x axis isĬomposed of dates and can be used to place lines at particular dates. ![]() graph twoway tsline high low, tlabel(01apr2001 01jul2001 01oct2001, format(%tdmd) ) Here we change the format of the date to be month and day. Option where we can supply in valid format that we would supply We can change the format of the display of the date variable using the format() graph twoway tsline high low, tlabel(01apr2001 01jul2001 01oct2001) Ttick(), tmlabel(), tmtick(), and tscale(), seeĭetails. Other options that can be used in a similar way include For example, say that we wanted the x axis to be labeled Understand that the x axis is a date variable and are much easier to In addition to these benefits, there are options we can use that Next, note that the labels for the xĪxis are labeled much better with more logical values having been chosen. > What I'd really like is for the numerical x labels to be there (stata default is fine) but with these additional vertical lines being labeled somewhere, there is space on the graph but I can't figure out how to do it. This is because Stata knew, from the tsset command, what the time I can tell it to put some of the tick marks back on by writing xlabel ( 25 50 '2 Stars'), but that also looks strange. Note that we did not need to specify date in the command. Now we can use graph twoway tsline to graph the data. Time variable: date, 02jan2001 to 31dec2001, but with gaps To tell Stata that the variable date represents time and that its Graph twoway line we can use graph twoway tsline which is specifically designed for making line graphs where the Labeling the x axis since these are date values. Also, it could be difficult to change the values Properly labeled with the dates, but the selection of the values labeling thisĪxis could be better. We could use the graph twoway line command to graph the high and low closing price for the year, as shown below. High and low trading price for a given day and date which is a date This file has variables like high and low that represents the This data file contains data for all of the trading days in 2001. ![]() quietly regress alcuse i.id#c.This FAQ shows examples of graphing data where the x axis represents dates.įor these examples, we will use the sp500 dataįile that comes with Stata and we can use it via the sysuse command. Predicted values from this regression can then be plotted. In the nextĮxample, we regress alcuse on age interacted with id. We can also plot fitted lines using the xtline command. xtline alcuse if id < 10, overlay t(age) i(id) legend(off) scheme(s2mono) To do this, we add overlay to our command. Suppose we are interested in seeing all of the above lines in one plot. This example generates plots for the first 9 children’s observations in the file xtline alcuse if id < 10, t(age) i(id) scheme(s2mono) A separate plot will be created for eachĭifferent id value. The time variable we specify willĪppear on the horizontal axis. The outcome that we wish to examine,Īlcohol use, will appear on the vertical axis. We indicate that our time variable is age with t(age) and our This first example shows a line connecting the three time points broken downīy id (one plot per child). Produces plots in grayscale, because publications often require monochromatic plots.įirst, we read in the data file. ![]() Of alcohol use, alcuse, taken at ages 14, 15 and 16 for 82 children We will show a number of examples from a data file which contains a measurement The xtline command allows you to generate linear plots for panel data. ![]()
