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). In Partek® Flow®, the default numeric variable is the cell numbers.  Therefore, the Pie chart indicates the fraction of the whole cell numbers in each category.

To make a Pie chart, open a new Data Viewer session in Flow (Figure 1).

Select Pie chart from ‘Available plots’ on the left side and drag it to Add new plot in middle panel. Then select any data node to create a new empty Pie chart (Figure 2).

Categorical attributes that can be used for the Pie chart would display after any data node from the Data card on the left side of the Data Viewer has been clicked. 

Pick and drag the attribute, Sample name as an example here, to the Add data in the middle panel (Figure 3).

A Pie chart that demonstrates the fraction of the whole cell numbers in each sample has been created (Figure 4).

The specific cell number in this category and its percentage of total would appear when a cursor is moved over on it. For instance, Sample2 includes 2285 cells which accounts for 36.149% of the total cells in the study (Figure 5).

Once you are pleased with the appearance of the dot plot, push Save image button to save it to the local machine. The resulting dialog (Figure 4) controls the resolution of the image file. The image will be saved in svg format, and the default file name is Dot plot.svg

Use the Group order section of the control panel to change the order of the groups on the x-axis. Simply drag and drop a group label to a new position.
