FlowingData | Data Visualization, Infographics, and Statistics Filled Histograms Using Excel XY-Area Charts I recently showed how to create Histograms Using Excel XY Charts. This technique produces a human-friendly numerical X axis scale, which is easier to read and harder to be deceived by than the bin labels used by column chart histograms. The drawback of that technique is that it produces histogram bars in outline only, without a fill color. In this post I will show how to extend that technique to fill the bars, using the protocol from Fill Below an XY Chart Series with an XY-Area Combination Chart. I started with the data from Histograms Using Excel XY Charts. I added a row at the top of the data for the left edge of the chart, and another row at the bottom for the right edge of the chart. The calculated values in the middle column are based on the small table to the right. Area Value = Area Scale Min + (Time - Time Min) / (Time Max - Time Min) * (Area Scale Max - Area Scale Min) or something like this, depending on where the tables are in the worksheet: So let’s make the chart.

Datavisualization.ch ExcelRibbon.Tips.Net - Powerful tips on using Microsoft Excel Data Visualization: Modern Approaches Data visualization Data visualization or data visualisation is viewed by many disciplines as a modern equivalent of visual communication. It is not owned by any one field, but rather finds interpretation across many (e.g. it is viewed as a modern branch of descriptive statistics by some, but also as a grounded theory development tool by others). It involves the creation and study of the visual representation of data, meaning "information that has been abstracted in some schematic form, including attributes or variables for the units of information".[1] A primary goal of data visualization is to communicate information clearly and efficiently to users via the information graphics selected, such as tables and charts. Data visualization is both an art and a science. Overview Data visualization is one of the steps in analyzing data and presenting it to users. Data visualization refers to the techniques used to communicate data or information by encoding it as visual objects contained in graphics.
