Pie Chart

A Pie Chart is a type of graph that displays data in a circular graph. It gives you a snapshot of how a group is broken down into smaller pieces. Because the pieces of a Pie chart are proportional to the fraction of the whole in each category. In order to make a Pie chart, you must have a list of categorical variables (descriptions of your categories, like ‘cell type’) as well as numeric variables (e.g., cell numbers). The default numeric variable is the number of observations, e.g. samples or cells. Therefore, the Pie chart indicates the fraction of the whole observation numbers in each category.

To make a Pie chart, open a new Data Viewer session, select New plot > Pie chart from the menu on the left control panel. Then select any data node from the analysis pipeline which contains the observations you would like to view the break down of the groups, select the categorical attributes which will contains the groups:

You can also choose another categorical attribute to split the pie to multiple pie chart by selecting Content split by drop-down.

The specific cell number in this category and its percentage of total would appear when a cursor is moved over on it.

Accessing the Configure > Axes menu you can easily split the plot by another categorical attribute available.

If more than one categorical attribute were added to the data, Pie chart would have two different modes - Pointer mode and Zoom mode . The default is Pointer mode, the Zoom mode is accessed by clicking on the zoom icon and subsequently clicking on any slice of interest.

Once you are pleased with the appearance of the Pie plot, push Export image button to save it to the local machine or click Save button to save the Data Viewer. The resulting dialog controls the Format, Size and Resolution of the image file. The image will be saved in your favorite format (.svg, .png and .pdf).
