Excel is powerful data visualization and data management tool which can be used to store, analyze, and create reports on large data. It can be used to visualize and compare data using a graph plot. In excel we can plot different kinds of graphs like line graphs, bar graphs, etc. to visualize or analyze the trend. In a combination chart, we can plot more than one kind of chart in a single graph. This chart allows the user to present and compare two different data sets that are related to each other (in a single chart). In combination charts, one can have two Y-axis, which allows you to have two different types of data points in the same chart.
