Next, we prepare our stacked bar graph, with minimal use of options at this point. G mathgrowth_yes = round(runiform(),0.01)Īt this point, our data looks as below.

We start by simulating the data using the code below. Bar graph command in STATA is very powerful and it can make data manipulations/calculations in itself, however, this post suggests a rather simplistic approach to preparing a stacked bar graph which uses already prepared data.

While making any graph in STATA it is important to have the data in the form suitable for making the desired graph. We will use data on school pupils in grades one to four, where for each grade we show percentage of pupils based on their performance compared to the previous year (those with and without growth in math scores).

Now you can change Date Levels, and have pixel perfect width Bar Charts along the way!

You can put Parameters on there for Marginal Histograms, or whatever other calcs you need, just make sure it's Continuous! You can expand on this however fits your needs. In order for this to work, after you have put the Size calculation on the view, right click and set it to a continuous dimension. Change the size mark to fixed, and drag the size calc onto the mark. Once we have that calc, our job is super simple. Here, the changes our dates to the level configured in the parameter, and calculates the difference in days to give the correct number of days in a particular year, quarter or month (week and day also apply, however, those values are static). The calc above finds the number of days in any year, quarter, month, etc… by taking the date difference in days from the date in question, and the next unit in line. So, we adjusted the calc to tell us how many days are in each unit as the Date Level changes. However, not all years have the same number of days, just like not all months have the same number of days. For instance, the year would be January 1st, the month would be the 1st of the month, the week would be the 1st day of the week, and so on.

As we change date levels, we plot the bar chart on the 1st day of the date level. When we tried this out for ourselves, we had the X-Axis as each day across the range of our data. This technique works for the calc/field as well. Once you complete Step 2 and set the size mark to fixed, drag a parameter onto the size mark to make the units dynamic. Thanks to the Data + Tableau + Me website, we have the secret to get the perfect bar widths.
