Span chart, also known as a range graph, floating graph, difference graph, high-low graph, shows dataset ranges between a minimum value and a maximum value:

When you work with some statistical data such as lifespan, weight, or height of the specific type of pets, you have different charts and diagrams to compare them. The box and whisker chart is one of the useful graphical representation of statistical data that that shows the median, quartiles, and extreme values at one plot.

A bullet graph (the name by its creator Stephen Few) or bullet chart (in Microsoft office) is designed to demonstrate the difference between the target value and the actual one. Sometimes there are ranges of performance enabled beside the current value bar – they show something like "low", "medium" and "high" or "poor", "satisfactory", "good" and "excellent" value ranges:

A bullet graph (the name by its inventor Stephen Few) or bullet chart (in Microsoft office) generally is used to display progress towards the specific target:

Let's suppose you have three different business plans that were presented to receive startup business loans with the repayment term of one year. They all look well crafted, with realistic and robust goals for the rapid development of their business. A decision that you need to make is which of the submitted projects will receive approval for the startup loans. There are several ways to compare different business plans, and each of them has its advantages.

If you start a new business, create a new product, or change a business model, break-even analysis lets you find out at what stage your company, product, or service will become profitable. Break-even point is the stage where you have no profit yet but have no loss already. However, there are many preceding and following stages important for the investor. The investor wants to know not only how quickly the initial investments will pay off, and extra income will be received, but also how quickly the normal profit and the economic profit will be earned.

A revenue the company generates from selling the products or providing the services should cover the fixed costs, variable costs, and leave a contribution margin. The point where the total operating margin (the difference between the price of the product or service and the variable costs per item or customer) covers the fixed costs is called a break-even point.

Manual data entry into spreadsheets and especially entering data into text cells leads to many errors. Excel data validation tools allow you to reduce the inaccuracy of Excel data entry by restricting the set of possible values to a pre-defined list. Users can select the item from a drop-down list with few choices, instead of typing text into the data entry form template.

When you import data into Excel spreadsheets from Internet pages or CSV files, Excel fails to recognize some numbers and converts them to the default text type. Temporarily changing Excel settings helps to reduce the amount of manual work and the number of errors on replacing comma to point, dot to comma, semicolon to comma, etc. Also, you need to change decimal delimiter settings for printing or exporting data for international users.

Excel pie charts are useful to display fractions of a whole by splitting a circle into sections. Each section looks like a slice of a pie and represents a category. Such a layout makes it easy to observe relationships between parts, but the smaller becomes the slice (less than 10%) – the harder becomes to estimate it visually.
