{title:Description}

{pstd}
{cmd:rddidplot} is a postestimation command for {cmd:rddid}. It generates side-by-side RD plots
for the Treated and Control groups using {cmd:rdplot} from the rdrobust package.

{pstd}
The command reads the estimation sample, bandwidths, cutoff, and variable names from the
{cmd:e()} results left by {cmd:rddid}. You must run {cmd:rddid} before calling {cmd:rddidplot}.

{marker options}{...}
{title:Options}

{phang}
{opt title(string)} specifies the overall title for the combined graph. The default is
"Difference-in-Discontinuities". Individual panels are labeled "Treated" and "Control".

{phang}
{opt cilevel(#)} specifies the confidence level for the confidence intervals drawn by {cmd:rdplot}.
The default is 95. Set to 0 to suppress confidence intervals.

{phang}
{it:graph_combine_options} allow you to customize the combined graph. Any options not recognized
by {cmd:rddidplot} are passed directly to {cmd:graph combine}. For example, you can pass
{cmd:xsize(10)} or {cmd:ysize(5)} to control dimensions.
