Draw a circle in an Excel chart

By default, Excel has a limited number of charts. That does not mean that those are the only charts one can create. It turns out that with a little imagination and creativity, we can format and configure the default charts so that the effect is like many other kinds of charts.

One of the more versatile of charts is the XY Scatter chart. We can use it as the base for many data visualization tasks. Recently, for a client, I used one to create a radial org chart as in Figure 1. Such a chart is also called a Node-Link chart or a Reingold–Tilford Tree.

Figure 1 – Example of a radial org graph created in an Excel XY Scatter chart
after removal of all identifiable information and the obfuscation of data
necessary to protect the client’s confidentiality.

A lot of “out of the box” work into making this chart. One key element was the set of equidistant concentric circles that provide a visual reference for the small colored dots. This note demonstrates how to create concentric circles in an Excel XY Scatter chart.

Worksheet as a chart – multiple conditional formats

Several years back, I wrote an article on how to use multiple cells to simulate conditional formats that involved more than 3 conditions. Three versions of Excel later, I still receive requests related to this post. So, I updated it to include more screenshots and a downloadable file.

In Excel 2003 and earlier, conditional formatting works well for up to three conditions. But even when the number of conditions exceeds that limit, it is possible to do without any programming support. For example, one possible way to show twelve possible rankings through color is shown below.

Excel Services Interactive View

Analyze data with Excel on the web

Microsoft has introduced a new web based capability that extends its Excel Services offering.  This new capability provides a limited interactive view of any table in a web page.

An introduction to this service is below.  For those interested in additional capabilities and more advanced and useful capabilities see:

For the consumer:

Learn more about Interactive View

Analyze a table in any web page with a dynamic interactive view

For the developer:

Implement the Interactive View feature for 1 table

Implement the Interactive View feature for multiple tables

Improve the formatting and layout of the 'Interactive View' buttons

As an example, the image below shows a table, the Interactive View button, and the result.

Align Primary and Secondary axes

There are instances when there are data series plotted on both the primary and secondary axes. For example, suppose we want to plot the two series A and B in Figure 1, with the elements in column B as the x-axis values. The A series will be a column cart on the primary axis and the B series will be a line chart on the secondary axis.

Highlight row and column of active cell

By default, when the user selects a cell, Excel highlights the row and column by changing the color of the associated row and column headers. This tip shares multiple ways to highlight the row and column in more obvious ways as well as a way to highlight the cell in a specific column in the same row.

The emphasis is on the use of conditional formatting to accomplish the task. The minimal VBA code required to make it work is the same single executable statement for all of the different highlighting options!
