Stata graph combine legend

Stata has excellent graphic facilities, accessible through the graph command, see help graph for an overview. The most common graphs in statistics are X-Y plots showing points or lines.

These are available in Stata through the twoway subcommand, which in turn has many sub-subcommands or plot types, the most important of which are scatter and line. I will also describe briefly bar plots, available through the bar subcommand, and other nortrac loader types.

Stata 10 introduced a graphics editor that can be used to modify a graph interactively. I do not recomment this practice, however, because it conflicts with the goals of documenting and ensuring reproducibility of all the steps in your research. All the graphs in this section except where noted use a custom scheme with blue titles and a white background, but otherwise should look the same as your own graphs.

I discuss schemes in Section 3. In this section I will illustrate a few plots using the data on fertility decline first used in Section 2.

To read the data from net-aware Stata type. Note that you specify y first, then x. Stata labels the axes using the variable labels, if they are defined, or variable names if not. The command may be abbreviated to twoway scatteror just scatter if that is the only plot on the graph.

We will now add a few bells and whistles. Suppose we want to show the fitted regression line as well.

In some packages you would need to run a regression, compute the fitted line, and then plot it. Stata can do all that in one step using the lfit plot type. There is also a qfit plot for quadratic fits. This can be combined with the scatter plot by enclosing each sub-plot in parenthesis. One can also combine plots using two horizontal bars to separate them. Now suppose we wanted to put confidence bands around the regression line. Stata can do this with the lfitci plot type, which draws the confidence region as a gray band.

There is also a qfitci band for quadratic fits. Because the confidence band can obscure some points we draw the region first and the points later.

You could specify a label for the y-axis using the ytitle option, and omit the rather obvious legend using legend off. Here we specify both as options to the twoway command. To make the options more obvious to the reader, I put the comma at the start of a new line:. It is also possible to label the points with the values of a variable, using the mlabel varname option. In the next step we add the country names to the plot:.

One slight problem with the labels is the overlap of Costa Rica and Trinidad Tobago and to a lesser extent Panama and Nicaragua. We can solve this problem by specifying the position of the label relative to the marker using a hour clock so 12 is above, 3 is to the right, 6 is below and 9 is to the left of the marker and the mlabv option.

There are options that apply to all two-way graphs, including titles, labels, and legends. Usually a title is all you need. Stata 11 allows text in graphs to include bold, italics, greek letters, mathematical symbols, and a choice of fonts.

Logit Interactions 3D margins More complex interactions Main graph types Two main types A scatter plot:. Where did these labels come from? A line plot. By default graphs are overwritten, can we change that?

You can include such computation between. You are curious how the variance changes when the mean of a dummy variable changes, so you decide to use twoway function to show you the graph. Area graphs twoway area draws an area from the bottom of the graph till the first variable named. It is useful for drawing confidence intervals. If you mess that up you get modern art.

Bar graphs and variations thereof twoway bar is a low level way of making bar graphs Low level means that you need to do more data preparation, but in return get a lot of freedom The easier but less flexible alternative would be graph bar.

Both graphs have the same legend so I want one legend to disappear. But since the bar graphs themselves are a kind of combined graph, legend off won't work. The legends are automatically produced by Stata.

As soon as I started to think about what by does, I found the answer myself. One has to toggle off the legend via legend off within by :.

Question feed. Stack Overflow works best with JavaScript enabled.Graph legends are an important part of data representation, as they enable the reader to better under stand the figure infront of them while not cluttering the figure itself.

Legends can often be seen next to graphs describing some of aspect of a graph. For more information on graphs see other articles such as: bar graphs, scatter plots and histograms. The dataset used in this article will be the mtcars dataset as it comes with base R. More specifically, in aes we color the point depending on the number of cylinders. Now we can add another layor by giving each type of transition a different shape through shape in aes. Additionally, you can augment the labels for both colour and shape with labs.

To change the legend position use the theme modifier in ggplot. From there you can choose top, right, bottom, left, or none removes the legend. To put the legends inside the plot create column vector of size 2 the first value refers to the x coordinate. To ensure that the whole legends is within the graph use the legend. There are other cool things you can do to the legend to better customize the visual experience by adding more to the theme modifier such as:.

Sometimes you may want to remove a legend for the sake of graph readability or to reduce clutter. You can alternately remove legends or components of legends with guides. In Stata the legend is automatically added when you create a graph with multiple lines.

However there may be instances where you would still prefer to have a legend on a single line graph or possibly no legend on your graph in general. For those times just add legend on or legend off. Legend position can be changed with the positioncoland ring modifiers in the legend function. Here position refers to where the legend is placed with respect to the center of the graph using clock directions i.

In the case where you are dealing with a two-way or a combination of graphs, augmenting the legend is exactly like above only now you must specify the line which you want to augment. Take this example from the stata manual on two-way graphs:.

Here they change the legend label for the first 2 lines. In regards to legend positioning, the same rules discussed above apply. LOST Menu.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am trying to combine multiple graphs in Stata using the command graph combine. The individual graphs are produced from the community-contributed command ciplot. The problem is that the y-axes of the graphs start in slightly different positions, due to the different width of the labels of individual ticks.

The problem gets even worse when larger discrepancies between these labels exist. Is there a way to force the y-axes to start from the same point in the graph region? One way to improve the graph is using the titlegap option. But it may not be satisfactory because manual tweaking is involved, and the result won't be perfect. Furthermore, if many graphs are being made, incorporating the change into the code might turn out to be cumbersome.

The outergap option provides a similar solution. Note that you cannot use the ylabel option in ciplot to specify the tick labels because you do not know a priori the actual tick values. Learn more.

Experimenting now with: 1 creating small dataset with estimates and CI using statsby 2 graphing using metan. Roberto's solution can also be generalized easily so you do not have to specify yourself the number of spaces required again based on the maximum number of decimals. A tick's label width in this case clearly depends on the number of decimals.

There are two main problems here: ciplot does not allow the format of variable levels to be specified in the y-axis label. Pearly Spencer Pearly Spencer November 27, in Uncategorized No comments. One useful command in Stata is graph combine.

This command enables us to combine previously generated graphs saved as. This is useful because it helps us make visual comparisons. Below is a simple example using the built in auto. Of course, you are not limited to just combining two graphs, you can combine as many graphs as you like and arrange them in single rows, single columns or in a grid e.

You arrange the graphs using the row and column options. When you have a grid more than a single row or columnby default, stata will first fill out the grid from left to right across columns, and then down rows. If you want to fill down columns first and then across rows, you use the colfirst option after the main arguments of the function for example:.

There are other cool options you can use with graph combine such as xcommon and ycommon that tells stata to make sure the axis scale and labels are the same across all graphs — which helps a lot for comparing.

Hello, I combine several graphs produced by -xtline- together. However, the default option is that each individual graph has its own legend box. So how can I make all the graphs share just one legend box?

Each graph has exactly the same legends. Tags: None. Marcos Almeida. I have not tested it yet, but there is a user-written program - grc1leg - aimed, as the title implies, at using graph combine with one legend.

Hopefully that helps! Comment Post Cancel. Martyn Sherriff. There is also grc1leg2, which is an 'update' of grc1leg. In addition, grc1leg2 suppresses the legends in the individual graphs and adds a common legend taken from one of them. Optionally grc1leg2 can also replace the separate xtitles on each of the individual graphs with a single b1title on the combined graph.

Optionally grc1leg2 can also alter the textsizestyle of the text labels in the common legend. All other attributes of the common legend are inherited from the legend on the component graph.

Cheers, Martyn. Originally posted by Marcos Almeida View Post. Originally posted by Martyn Sherriff View Post. Maraa Barschkett.
