A histogram chart visualizes the distribution of continuous data. Each column in the histogram chart represents the frequency (amount) of the data within the specific range.
Excel 2016 offers several new pre-defined charts, including the histogram chart. This pre-defined chart makes possible to create different types of histogram charts with little effort.
There are several ways to create a histogram chart in Excel. By the moment, Excel uses two different algorithms to calculate the data for a histogram chart:
Histograms show the distribution of numeric data, and there are several different ways how to create a histogram chart.

However, you cannot use Excel histogram tools and need to reorder the categories and compute frequencies to build such charts.
A histogram chart is often confused with a bar chart because it displays data using bars of different heights. The 'true' histogram chart shows the distribution of numerical data. Each bar of the histogram represents the count of data values within the specified range. See more about different types of histogram charts in Excel.

The dimensions have different qualitative meanings, and, if you choose a bar chart to plot such data, you need to create a separate graph for each aspect. A much better option is to normalize the data and use a spider chart, which renders multiple axes with the same scale.
Because of different standards of different countries and cultures, there is a lot of situations when you need to change commas to dots, decimal points or dots, decimal points to commas in an Excel spreadsheet:
