Histogram Chart
A histogram is used to classify (continuous) values of a metric into specific bins. It is a graphical display of data using bars of different heights. It is similar to a Bar Chart, but a histogram group metric values into ranges (bin size) and you can decide what ranges to use. The bin size can be set as per the requirement. We can also show the cumulative sum line of the values under each bin.
Inputs
Metrics: 1 metric Attributes: 1 attribute. Use as Filter Option - Not Available
Data labels
We can format the data labels and bin total also. You can see the attached screenshots below.
Bin Size and Cumulative Sum
Bin Size:
Bins are the towers or bars that make up a histogram. Each bin’s height indicates how many values from the data fall within that range. Below is the screenshot of the property to modify the bin size.
Default bin size:
Modified bin size:
Cumulative Sum:
A cumulative histogram is a mapping that counts the total number of observations in all bins up to the chosen bin.
Markers
When the Vitara histogram chart shows the cumulative sum line, we can make a chart to show a marker at each intersection of each bin and the cumulative sum line. The type and size of the marker customizable.
Below is the example of histogram chart shows the cumulative sum line with markers.

Zero Value Bar
In Version 5.1.1.010, we included a new feature that allows users to show zero value bars. This feature can be enabled under the “Histogram” tabs, where it can be used to display metrics, whose values are zero.
