Change order of Bars in combomarginsplot

[Tom Ford]

Hello. I am running a simple regression, and I want to plot the marginal means of my results

I am doing something like this.

* create relevant data: car brands
sysuse auto
encode make, generate(make_en)
gen brand = word(make, 1)
encode brand, generate(brand_en)

* run main regression to examine the effect of brand on price
reg price ib1.brand_en
* estimate marginal means of brand on price.
margins brand_en, post saving(brand_marg, replace)

Now, my objective is to plot marginal means, and I do the following.

combomarginsplot brand_marg, scale(0.60) scheme(s1color) recast(scatter) ylabel(,grid) plotregion(margin(vlarge)) ytitle("Price" "Marginal means") xtitle("") title("")

Which works well and produces this plot.

How can I change the order of the coefficient bars in my combomarginsplot? For instance, Cad. and Linc. have very high prices: how can I put them at the start of my combomarginsplot?

thanks a lot in advance for your help

I am just seeing this. You do not in fact need -combomarginsplot- to produce this, as this is simply a graph from a single call to margins, not a graph that combines the results of several calls to -margins-.

The ordering in the graph is based on the ordering created by -encode-. You could explore -sencode- (a user-contributed SSC package) if you need more control over the encoding order.
