Tabulo attribute generator#
Tableau is a SQL generator & displayer of results. Since Tableau assumes aggregation it will add sum() to amount to give us expenses by month.I don’t want to misrepresent Joe’s encyclopedic knowledge of Tableau here, if there are any mistakes in these notes from our conversation they are almost certainly mine. To put a number (dimension) onto the table, drag a dimension, in this case amount, onto the text mark. That is, aggregation is its initial position, and for whatever reason it picks year first. We use text for a text table.įirst note that we change date from year(Postdate) to Month(Postdate) as Tableau, by default, usually assumes we want to sum values by year. You do that by dropping it onto the marks tab and then selecting text, line, bar, or however you want to display this. To fix that, we add a measure to the table. When you first pick a row and column dimension, Tableau does not know what value you want to put at each row, column intersection. For example, above each row contains both category and description or (category, description) pairs. You can also think of rows the same way, as being a collection of whatever you assign to the row line. A programmer would call this (category, description) a tuple. This makes sense if you think of the idea of a column as being all the fields you have added to the column line at the top. If you were to flip the rows and columns of the text table above, you get two columns of columns (category and description) by month. We put dimensions on the row and columns. Of course, there are ways to see more than one dimension on a chart by, for example, adding more than one line to a line chart and making use of both the left and right-hand axes of a chart.)
Because those are hard to visualize, it’s easier to use a text table. (Note: If this was a chart it would be a three-dimensional chart. You could use any other description, too. Here, we’ll add a third dimension: payee. If this was a chart you would say that a dimension is an axis, like the XY-axis in a scatter chart.Įxpenses by date, category, and description In this table, we add a second dimension: date. This table has one dimension, category, and one measure, expenses. Here are some examples of what your text table can show: Expenses by category So, a text table will by default display aggregated data. In Tableau, fields are grouped by dimension and measures on the left-hand side of the worksheet editor, like this:īy default, Tableau is designed to work with sums, which they call aggregation. A dimension is anything that is not a number, such as dates, or text fields like category.A measure is a number, which is anything you can do math on.There are long definitions in various tutorials that try to explain what dimensions and measures are. Defining measures and dimensionsįirst, we need to understand two concepts: measures and dimensions.
Tabulo attribute download#
You can easily download your credit card into one of the supported data sources, like PostgreSQL. For the data, I’m using my credit card statements. If you’re new to Tableau, see our starter article Tableau: Getting Started with Real Examples. Use the right-hand menu to navigate.) Putting data in Tableau (This article is part of our Tableau Online Guide. The easiest way to picture a text table is to think of sales or expenses by date. It’s a table, not a chart, with one or more values in the rows and one or more values in the columns. You can think of a text table in Tableau as the same as a pivot table in Excel.
