In this tutorial, we’ll demonstrate how to draw a simple Bar Chart in Glimpse.
First, enter in the data: open up the Data Grid, which can be accessed by pressing the button on the bottom to open up the section:
Double-click on the row along from 1 to create a new data field (or alternatively, going Data > Add Data Field… from the top menu).
Type in “Category” as this will be the first column where the category labels will be contained and after press Create.
To create a second field column, double-click on the highlighted row anywhere to right of the Category column (or go Data > Add Data Field… on the top menu). Type in “Values” and press Create.
To enter in the data into the cells, simply double-click on a cell that’s below a field and start typing. For the Category column write “A” and for the Values column write “28”.
Now to create a new row, go Data > Add Data Row on the top menu, or an even quicker way is to have a row selected and press ⌘ + C (to copy) and ⌘ + V (to paste). Nine rows in total are needed.
Edit the table in the Data Grid to include this dataset:
The Data Grid can be closed by pressing the button on the top-left. Two field tokens will now appear under Fields:
Both field tokens need to have a Measure type assigned to them. To do this, first press the field token and then in the Inspector panel (under Data > Field) select an option from the Measure dropdown menu:
For the field Category, set the Measure to Nominal, and for the field Values, set the Measure to Quantitative.
Drag the field Category into the X encoding and the field Values into the Y encoding.
Through the Inspector panel under Viz > Mark with the dropdown menu at the top, select the Bar option to convert the visualization into a Bar Chart:
The finished visualization should look like the below:
