Scrollable Bar Chart Mod for Spotfire®

Version 1.0.0, released March 2022

The scrollable bar chart is a similar visualization to a usual bar chart, excepts it adds a scroll bar if more bars needs to be shown instead of decreasing the bars size and labels of the bar are always visible, readable and without ellipsis.

Data requirement

Every mod handles missing, corrupted and/or inconsistent data in different ways. It is advised to always review how the data is visualized.

To make the scrollable bar chart work properly, the underlying data must be formatted in a certain way. A data table with at least two columns is required. At least one column should contain categories and a second column should contain the values for each categories.

In the scrollable bar chart configuration in Spotfire, we would specify the 'State' column from the data table above as category axis and the 'Sales' column as our value axis.

Optionally the 'Region' or 'State' categorical columns could be used to color the bars.

The end result will look something like this:

Configuring the chart

Once the area chart is configured and has data provided, you can configure it to show also value and percentage next to the category label. Also sorting by value is possible.

Using the chart

Marking

Clicking on a bar or a color in a bar will mark that data and in all other visualizations that uses the same marking.

Vertical scrolling

If the bar chart is longer than the visualization area a scrollbar will be displayed.
