Compare Quantitative Performance with Bar Graph Visualizations
Bar Graphs are one of the most popular and well-understood data visualizations used in BI Dashboards. Bar Graphs are especially useful when comparisons are critical to an understanding of the data.
Great visualization for executive dashboards
Bar Graphs — sometimes called Bar Charts — are easy to understand and are a great way to communicate important comparative information. Bar Graphs work especially well when comparing ten or fewer data items across a single quantitative variable. For displays including more than ten items, try using a Heat Map or Treemap instead. Our Bar Graph visualizations can be oriented horizontally or vertically in information displays, making them easier to incorporate into multi-visualization layouts.
Datawatch's Bar Graph data visualizations give you a number of different display options and are easy to work into almost any Executive Dashboard or other type of information display. Like Scatter Plots, Treemaps and the rest of our information visualizations, our Bar Graphs are designed to work with real-time streaming data sources as well as time series and static data. The simplest form of the Bar Graph is completely intuitive.
Support for Edward Tufte's best practices in data visualization
The design of our Bar Graph, like all of our information visualizations, emphasizes the data itself and eliminates unnecessary display items. For example, our grid lines are designed to be background items that help make the Bar Graph easier to comprehend quickly without being a distraction. We go further by enhancing the "data to ink ratio" by allowing Edward Tufte-syle grid line representations in which the grid is displayed by removing "ink" from the bars themselves.
Grouped Bar Graphs
The Grouped Bar Graph is an excellent way to show information about categorized groups of data in a single information visualization. Different colors make it obvious how items are related and provide an easy-to-read display.
Interactive analysis of real-time data
Bar Graphs lets users plot historical data and predict future trends in seconds. They can slice and dice their data, drill down to view details, and compare several small or large time segments by creating new breakdowns on the fly. Simple, easy-to-read hover displays pop up when the cursor lingers over a single bar – or a selection of bars – in the Bar Graph, making it very easy to compare information about separate events in the timeline. Like all of our visualizations, the Barseries can handle real-time streaming data feeds along with historical static data inputs.
