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 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:

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.

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 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.
This is the third, and last part of the tip How to create a mosaic plot in Excel (the second part is How to create a step Area chart for the Mosaic plot in Excel). The step area chart created in the previous part has invalid labels for both axes and no data labels:
