Sas sgplot vbar two variables

It seemed like an easy task.

sas sgplot vbar two variables

I assumed that there was some simple option that would change the scale of the vertical axis from counts to percentages. I checked the SAS 9. Assume that you want to display percentages instead of counts. However, sometimes you might want to use the SGPLOT procedure, especially if you want to add titles or reference lines, or otherwise change the default properties of the bar chart.


The Percent variable contains values in the range [0, ]. I sometimes like to use values in the range [0,1]. The same trick works if you want to create a grouped bar chart. In order to show grid lines in the background, the template for the FREQ bar chart uses semi-transparent bars, which results in the washed-out colors. Can you think of a different way to accomplish this task? His areas of expertise include computational statistics, simulation, statistical graphics, and modern methods in statistical data analysis.

Rick, thanks for sharing the trick. I had to use GTL to create two Y axes. It would be much easier if user have that control in VBAR statement. Second but also important missing option on VBAR is to specify the numeric format of labels. Third and last missing component that is bothering me alot these days is to control the order of character categories on X-axis. I have a related question, I would also like to add the Ns to the bottom of the bars - that way a person can get the percentages and also the total number per bar.

I was able to overlay 2 vbars, with the pct one being the second one and that works because they are on the initial scale so the percentages show at the bottom and the bars are not visible but there. Then I realized I was searching for: "sas 9. One-way frequencies and bar charts Assume that you want to display percentages instead of counts.

Please share sample data, a picture. What release of SAS do you have? SAS 9. Discussion stats.Horizontal and vertical box plots display the distribution of data by using a rectangular box and whiskers.

Whiskers are lines that indicate a data range outside of the box. Parts of a Box Plot shows a diagram of a vertical box plot. The bottom and top edges of the box indicate the intra-quartile range IQR. That is, the range of values between the first and third quartiles the 25th and 75th percentiles.

The marker inside the box indicates the mean value. The line inside the box indicates the median value. The elements that are outside the box are dependent on your options. By default, the whiskers that extend from each box indicate the range of values that are outside of the intra-quartile range, but are close enough not to be considered outliers a distance less than or equal to 1.

Any points that are a distance of more than 1. By default, these points are indicated by markers. Specify a value between 0.

A box plot is created for each distinct value of the category variable. If you specified a variable, then the values for that variable are used for the data labels.

If you do not specify a variable, then the values of the response variable are used. If n is not an integer, then it is truncated to an integer. If n is less than 1 or missing, then it is excluded from the analysis. Far outliers are points whose distance from the box is more than three times the length of the box. By default, the label of the response variable is used.

Specify a value from 0. All rights reserved. Previous Page Next Page. Description Horizontal and vertical box plots display the distribution of data by using a rectangular box and whiskers.

Default: 0. EXTREME specifies that the whiskers can extend to the maximum and minimum values for the response variable, and that outliers are not identified. Interaction: If your plot is overlaid with other categorization plots, then the first FREQ variable that you specified is used for all of the plots.

You can use the name to refer to this plot in other statements. Y2AXIS assigns the response variable to the secondary right vertical axis. If your plot is overlaid with other categorization plots, then the first FREQ variable that you specified is used for all of the plots.This is the 2nd installment of the " Getting Started " series, and the audience is the user who is new to the SG Procedures.

It is quite possible that an experienced users may also find some useful nuggets here. One of the most popular and useful graph types is the Bar Chart. Today, we will discuss the most common type, the venerable VBAR statement. In this article I will show you many small examples of bar charts with increasing information. Let us start with the most basic case, as shown on the right.

sas sgplot vbar two variables

This graph shows the frequency or counts by category with default settings. Click on the graph for a higher resolution image. The graph on the right shows the mean of city mileage by type. The title already mentions "Mileage by Type", so there is no need to repeat that information as the label of the x-axis. The label is suppressed by the x-axis option.

A legend is automatically created by the procedure to display the two items in the graph. The graph on the right shows the mean mileage by type, using options to create a different look and feel. We have also displayed the response value for each bar at the top. The axis lines and ticks are removed and y-axis grids are added. This results in a clean graph as shown on the right. Values for each group are stacked for each category, creating a stacked bar chart as shown on the right.

Now the bar height is the sum of all the observations for the category. Note, with SAS 9. Note, a legend showing the color used for each unique value of the group variable is shown. A group legend is displayed by default.

Bar values can be shown for each group in a category, as shown on the right. Note, the values are automatically rotated to a vertical orientation when the values will not fit in the space available. This statement allows to control the attributes for the group values for fill colors, contrast colors, marker symbols and line patterns. Creating such a graph requires some complex layout of the category axis, and a decision was made to avoid such complex axis layouts as this combination is relatively rare.

The resulting graph is shown on the right. Here we have a bar chart of actual sales by type, year and quarter. The year values are side-by-side and the quarter values are stacked. So, each "cluster" is really a cell in the panel. Normally, the cell header is at the top of each cell, with a header border. For all the examples above, the data contains one or more classifier variables with one response variable.

This is what is sometimes referred to as a "Tall" structure. In such a case, it is possible to create a clustered bar chart without transforming the data, by layering the data for each column as shown on the right.

Normally, the second layers would cover the first, but we have made the 2nd layer bars narrower, so we can see both. Finally, the bars need not be overlayed on category centers, but can be "offset" to be side-by-side, or even a bit overlapped as shown on the right.

Here the bar widths are 0. There is one restrictioin when layering multiple VBAR statements.Bar Charts are used across all domains, including business, finance, banking, clinical and health and life sciences. The data used for these graphs is shown at the bottom of this post.

With SAS 9. Using this option, you can create a cluster grouped Bar Chart as follows:. Bar charts with aesthetic skins in SAS 9. This option creates an aesthetically pleasing visual effect for the Bar Chart. Data The data set prdsale used for the above examples is merely a cleaned up version of sashelp. You can easily use sashelp.

I am new to SAS and wanted to know if there was a simple code to assign the variables in the chart. I am making charts but my variable colors keep switching over years. The bar colors are based on active style. Each distinct class level in the group variable gets a color from the GraphData elements in the style. In SAS 9. How do I change the order of the variables in the stacked bar chart using sas 9. Let's say you wanted as the bottom part of the graph with the on top, the opposite of what your chart is doing?

Hi, Isaac. Tags bar charts statistical graphics.

Leave A Reply Cancel Reply.Sanjay's example was a chart that showed medical conditions classified according to the scale "Mild," "Moderate," and "Severe.

If you are running an earlier version of SAS, you can use a trick that accomplishes the same result. The trick is to create a set of all categories in the order you want them to appear in the legend and prepend these "fake observations" to the top of your data set.

All other variables for the fake observations are set to missing values. However, the missing values in the other variables prevent the fake observations from appearing in the graph. The exception is a graph that shows ONLY the categorical variable, but you can handle that case, too. Let's create a data set that shows the problem. The SasHelp. Heart data set contains observations about patients in a medical study.

There are several problems with this scatter plot. However, that effort was thwarted by the fact that the default order of the colors is determined by the order of the two!

How can I get the correct colors, and also get the legend to display the "Underweight" category? The "fake data" trick is useful in many situations, not just for legends.

I have used it to specify the order of a categorical variable in a graph or analysis. In this graph, the legend display all possible categories, and the categories appear in the correct order. Adding new observations can create problems if you aren't careful. Unless you correct for the fake data, the bar chart will show observations and display a bar for the "Underweight" category, which is not part of the original data. The DATA step that appended the fake data also added an indicator variable, which you can use to prevent SAS procedures from displaying or analyzing the fake data, as follows:.

Notice that the bar chart shows only the original observations. In summary, by prepending "fake data" to your data set, you can ensure that all categories appear in legends.

As a bonus, the same trick enables you to specify the order of categories in a legend. In short, prepending fake data is a useful trick to add to your SAS toolbox of techniques. His areas of expertise include computational statistics, simulation, statistical graphics, and modern methods in statistical data analysis.

I have attempted this trick in a legend for a proc gchart vbar. It seemed not to work. Is that to be expected?

I had difficulties assigning the right colors patterns to my incomplete data as well. This was easily solved by creating the patterns as they appear in the data using a call execute.

As mentioned in the first paragraph, you can use a discrete attribute map. Data that excludes a valid category Let's create a data set that shows the problem.

Dirk Van Krunckelsven on October 3, pm. The legend however continues to bug me, Rick Wicklin on October 3, pm.The graphs will be separate plots automatically scaled the same to facilitate direct comparisons. Here are the first 10 observations in each BY group:. To generate a similar plot to the previous example, you need to have separate variables instead of BY groups. If you have your measures stacked in one column as in the data set above, this code shows how you can reshape the data set and generate the plot:.

The data set now has the layout in the following partial print showing the first 10 observations:. The following statements delete all of the previous graphs that have been written to the WORK. GSEG catalog:. Run the two plots separately and store them in a graphics catalog. ODS Graphics must be disabled. Use AXIS options to ensure the same scaling on both plots.

That is, you can plot both a normal curve and a lognormal curve on the same graph, but you cannot plot two different normal curves. SAS 9. Run the plots separately and store them in a graphics catalog. Use AXIS options if necessary to ensure the same scaling on each plot.
