Data representation
using bubble chart
Bubble chart is similar to that of a scatter plot where the
data points of a scatter plot are replaced by a bubble. We can use bubble chart
if we have three data series with different values. The size of the bubble
depends on one of the variable.
Bubble charts are generally used to represent financial
data. We can use a bubble chart if we have data in the following format:
o
Three variables are needed for a data point i.e.
X,Y and size of the bubble.
o
We can also represent negative data values in a
bubble chart. They are represented using white bubbles and we cannot format
those bubbles.
This link provides more details about how to create a bubble
chart, format the bubble chart and an example for bubble chart.
Difference between a
bar chart and histogram :
In a bar chart
the data in the columns are positioned in a label that represents categorical data and the height of the
column represents the size of the group defined.
In case of a histogram
the columns are positioned over a label that represents a quantitative
variable. The column variable can be single value or range of values.
