Mlabel command to label datapoints

[Saini Smriti]

Hello
I am trying to label the datapoints in the graph below. I want to mark the number of machines by year. Eg, For 2017-2018, there were around 8400 subsidised rotavators. I am using mlabel command but to no help. Am I using the wrong command or wrong order ? Please help.

twoway (line Rotavator Seed_Drill_cum_Zero_Till year), xlabel(, valuelabel, mlabel, sort)


Thanks

mlabel() is an option, not a command. If it were a command you wouldn't implement it like that.

A deeper problem with your syntax is that there are markers to label. Running this code will show some technique (and a horrible graph, but that is not the issue).

line invest year if company == 1 || scatter invest year if company == 1, ms(none) mlabel(invest)

Hello Nick
Thanks for the response. I corrected my mistake and used the following code:
twoway (line Rotavator Zero_Till year, mlabel( Rotavator Zero_Till )), xlabel(1(1)3, valuelabel)

However, it shows no labels on the line. The xlabels are for years.

I don't understand what is wrong with this.

Well, I have already explained what's wrong with it. Marker labels go next to markers. You have no markers. Markers are point symbols. See again #2 where the example shows that you can add markers to a line plot by adding a scatter command that suppresses the marker symbol and then adds marker labels.
