Bar Chart

Graphs present data as clearly as possible. To be able to interpret the results of the graph, you need to understand the types of graphs you have to choose from. Also, it is important to identify what makes one type of graph more suitable for some situations than the alternatives. The most commonly used are bar and line charts.

Bar charts are mostly used for categorical data; compare things between different groups, compare quantity, frequency, or ratio of each category, etc. A bar chart can have more axes in Graphite: one x-axis (Category) and several y-axes (Series). Also, there are 3 types of bars: vertical bar, stacked bar, and step bar.

Follow these simple steps:

1. Open or Create a notebook
2. Select New Visualization
3. Select a Dataset for your bar chart
4. Select Combination Graph
5. Choose your Category
6. Choose one or multiple Series; you can change the type of the bar or its color.
7. Select Save

Bar charts can be also used for time-series data. For example, you can track changes over time: suppose you work in a hospital and have a total number of patients admitted by December 2014. Through the height of the bar chart, we can see the differences between the days: on which day most patients were admitted, which days had approximately the same number of patients, etc.

We briefly went through the basics of the bar chart, now it's your turn to create some visualizations. Enjoy! 🙂
