Twoway graph X axis

[Tia Landry]

Hi all,

Would anyone know whether there is a similar over () function such as with the graph bar (asis) command that can be used with the twoway stacked bar command?

I have a created a stacked bar graph over weeks in the x axis and would like to also include months in the x axis as well.

graph twoway (bar AGE_N_0_4 week,color(black) lcolor(black)lwidth(medthick)) (rbar AGE_N_0_4 A2 axis ,color(gs7*0.9) lcolor(black)lwidth(medthick)) (rbar A2 A3 week,color(gs7*0.4) lcolor(black)lwidth(medthick)) (rbar A3 A4 week,color(dimgray) lcolor(black)lwidth(medthick))(rbar A4 A5 week,color(white) lcolor(black)lwidth(medthick)) (line THREE_WEEK_AVERAGE_COUNT week, lpattern(solid)color (red) recast(connected) msymbol(O))(line TWO_SD_THREE_WEEK_COUNT week, lpattern(dash)color (blue) recast(connected) msymbol(x))(line HISTORICAL_AGERAVE week, lpattern(dash)color (gray) recast(connected) msymbol(s)),xlabel(1(2)62,valuelabel angle(90) labsize(*1.0)tick)xtick(1(1)62) ytitle("X", size(small) height(4)) ylabel(,nogrid)graphregion(color(white)) ylabel(0(1)10, labsize(*1.0)angle(0))

Use a by() option instead.

Hi Nick,

I have tried that, however it is not quite what I am looking for. I don’t want to get 12 different graphs. I want one graph that gives me the week labels and under that the months under which the weeks fall. With Bar (Asis) I would have been able to do this by including two over() options.

Is there a way to group the weeks similar to how this Y axis is set up? does the twoway command support groups?

Yes and no. You just need to work out where on one axis values are to be plotted. For example, as in your plot, you could use positions say at 1 3 4 5 7 8 10 11 12 13 14 leaving gaps at 2 6 9. The code is simple in principle and a little tedious in practice.

search seqvar

should find a relevant paper, but many programs use the same logic.

Thank you Nick! I have used labmask before, I used it to create my week variable. However I am not sure how to incorporate labmask and the information you provided above into my command below. Do you have an example of a twoway graph where it has been used in the way I am hoping to?

Code:
graph twoway (bar AGE_N_0_4 week,color(black) lcolor(black)lwidth(medthick)) (rbar AGE_N_0_4 A2 axis ,color(gs7*0.9) lcolor(black)lwidth(medthick)) (rbar A2 A3 week,color(gs7*0.4) lcolor(black)lwidth(medthick)) (rbar A3 A4 week,color(dimgray) lcolor(black)lwidth(medthick))(rbar A4 A5 week,color(white) lcolor(black)lwidth(medthick)) (line THREE_WEEK_AVERAGE_COUNT week, lpattern(solid)color (red) recast(connected) msymbol(O))(line TWO_SD_THREE_WEEK_COUNT week, lpattern(dash)color (blue) recast(connected) msymbol(x))(line HISTORICAL_AGERAVE week, lpattern(dash)color (gray) recast(connected) msymbol(s)),xlabel(1(2)62,valuelabel angle(90) labsize(*1.0)tick)xtick(1(1)62) ytitle("X", size(small) height(4)) ylabel(,nogrid)graphregion(color(white)) ylabel(0(1)10, labsize(*1.0)angle(0))

Even with some experience I can’t happily read your code and have any precise idea of what you want to do.

To get more advice I think you need to post

* example data

* your graph so far

* details of what you to do further.

Please read FAQ Advice #12 and act on it.
