Timeline chart is a type of chart that visually shows the chronological sequence of past or future events on a timescale. The chart’s timescale can be in days, weeks, months, quarters, years or other units of time depending on the type of events shown on it.
Multi-category chart or multi-level category chart is a chart type that has both main category and subcategory labels. This type of chart is useful when you have figures for items that belong to different categories.
When visually comparing the values of multiple items, if the value of one item is greater than the total values of all the other items, you may want to emphasize it. You can do so by displaying the largest value in one bar and grouping the smaller values together in another bar in a combined clustered and stacked bar chart.
Mirror bar chart is a type of bar chart that comparatively displays two sets of data side by side along a vertical axis. The chart resembles the reflection of a mirror, hence the name “mirror bar chart”. The advantage of a mirror bar chart is that it illustrates two data sets side by side and therefore makes it easy to make comparisons and spot any differences between them.
In infographics and other visuals, I have many times come across a pie chart in which each slice has a different radius based on the percentage it represents: the slices representing categories with large percentages have larger radii (the plural of radius is radii), while the slices representing categories with small percentages have shorter radii. The advantage of such a pie chart is that it further emphasizes the relative importance of a particular category to the total and is useful when you want to draw attention to categories with large percentages. Also, it can be a visually nice addition to any dashboard, report or presentation. For all these reasons, I have decided to create this pie chart in Excel and share it with you.
