In a chart, a data table displays the data series in rows and the category values in columns.

When you’re working with dates or numeric bins, Tableau only shows the values that are represented in your data. If your data does not contain the complete range of values, the missing values will not be shown. For example, your data may contain data for January through May and September through December. However, there was no data recorded for June, July, and August. If you create a line chart in Tableau, the missing months will not be shown. You can optionally show the missing months to make it clear that there was no data recorded during that time. Show Note: You can replace missing values with a calculated field using the ZN() function. See Number Functions for details. Missing Values Hidden (Default) By default, missing values in a date range or numeric bins are not shown.
 Missing Values Shown You can show the missing values to indicate incomplete data.
To show missing values in a range, right-click (control-click on Mac) the date or bin headers and select Show Missing Values.
Note: You can also perform calculations on missing values that are shown in the view. To do this, open the Analysis menu at the top, and then select Infer Properties from Missing Values. For an example of this, see Predictive Modeling with Generated Marks. When you are working with fields that are not dates or numeric bins, Tableau hides missing values by default. For example, you may be showing workers and the number of hours worked in a particular month. If a worker didn't work at all that month, there may not be a row in the database for that worker. When you drag the Worker field to the Rows shelf, the workers that didn't work are hidden by default. You can show the empty rows by selecting Analysis > Table Layout > Show Empty Rows. Similarly, show the empty columns by selecting Analysis > Table Layout > Show Empty Columns.
Use pie charts to show proportions of a whole. The basic building blocks for a pie chart are as follows:
To create a pie chart view that shows how different product categories contribute to total sales, follow these steps:
Tableau aggregates the Sales measure as a sum. By default, Tableau displays a bar chart.
The result is a rather small pie. To make the chart bigger, hold down Ctrl + Shift (hold down ñ + z on a Mac) and press B several times.
If you don't see labels, press Ctrl + Shift + B (press ñ + z + B on a Mac) to make sure most of the individual labels are visible. You can make a pie chart interactive in a dashboard. For more information, see Actions and Dashboards. Note: Pie charts can also be used as a mark type in a visualization. For more information, see Pie mark. Check your work! Watch steps 1-4:
Which type of chart represents data through a series of columns and rows?In its simplest form, a table is a group of rows and columns of data.
What are categories and series in charts?Each chart type displays series differently. Often (but not always), series correspond to rows of data in the data range. Categories are "bins" into which the data from each series is sorted. Often (but not always), categories correspond to columns of data in the data range.
How do I display data table in Excel chart?Show or hide a data table. Select a chart and then select the plus sign to the top right. To show a data table, point to Data Table and select the arrow next to it, and then select a display option. To hide the data table, uncheck the Data Table option.
Which chart element shows all the data values and categories?On most charts, the X axis is called the category axis because it displays category names. Axis labels are words or numbers that mark the different portions of the axis. Value axis labels are computed based on the data displayed in the chart.
