Visualisation methods that show part (or parts) of a variable to it's total. Often used to show how something is divided up. shows the relationship of each part to a whole. goal seek. a what-if analysis comprised of the entire chart and all of its elements. what-if analysis. process of. Aug 6, In this post for our ongoing series on Displaying Data, I'll be looking at part-to- whole relationships. Part-to-whole relationships aren't just about.
If you have any kind of location data like coordinates, country names, state names or abbreviations, or addresses, you can plot related data on a map. A good example would be website visitors by country, state, or city, or product sales by state, region or city. When to use map charts?
ASK A BRAND
If you want to display quantitative information on a map. To present spatial relationships and patterns. When a regional context for your data is important. To get an overview of the distribution across geographic locations. Only if your data is standardized that is, it has the same data format and scale for the whole set. Gantt Charts Gantt charts were adapted by Karol Adamiecki in But the name comes from Henry Gantt who independently adapted this bar chart type much later, in the s.
Gantt charts are essentially project maps, illustrating what needs to be done, in what order, and by what deadline. You can visualize the total time a project should take, the resources involved, as well as the order and dependencies of tasks. But project planning is not the only application for a Gantt chart.
It can also be used in rental businesses, displaying a list of items for rent cars, rooms, apartments and their rental periods. To display a Gantt chart, you would typically need, at least, a start date and an end date.
Gauges are a great choice to: Show progress toward a goal. Represent a percentile measure, like a KPI.The ULTIMATE RGB PC Build Guide!
Show an exact value and meaning of a single measure. Display a single bit of information that can be quickly scanned and understood. The bad side of gauge charts is that they take up a lot of space and typically only show a single point of data. If there are many gauge charts compared against a single performance scale, a column chart with threshold indicators would be a more effective and compact option.
Multi Axes Charts There are times when a simple chart just cannot tell the whole story.
What graph shows the relationship of parts to the whole
If you want to show relationships and compare variables on vastly different scales, the best option might be to have multiple axes. But it comes at a cost. That is, the charts are much more difficult to read and understand. Multi-axes charts might be good for presenting common trends, correlations or the lack thereof and the relationships between several data sets. But multi-axes charts are not good for exact comparisons because of different scales and you should not use this type if you need to show exact values.
Use multi-axes charts if you want to: Display a line chart and a column chart with the same X-axis.
Data Visualization – How to Pick the Right Chart Type?
Compare multiple measures with different value ranges. Illustrate the relationships, correlation, or the lack thereof between two or more measures in one visualization. Save canvas space if the chart does not become too complicated. When using time in charts, set it on the horizontal axis. Time should run from left to right. Do not skip values time periodseven if there are no values. The numbers in a chart displayed as bar, area, bubble, or other physically measured element in the chart should be directly proportional to the numerical quantities presented.
Remove any excess information, lines, colors, and text from a chart that does not add value. More about data-Ink ratio Sorting. For column and bar charts, to enable easier comparison, sort your data in ascending or descending order by the value, not alphabetically. This applies also to pie charts.
Use labels directly on the line, column, bar, pie, etc. When using monetary values in a long-term series, make sure to adjust for inflation. For comparing the same value at different time periods, use the same color in a different intensity from light to dark. For different categories, use different colors.
The most widely used colors are black, white, red, green, blue, and yellow. Keep the same color palette or style for all charts in the series, and same axes and labels for similar charts to make your charts consistent and easy to compare. Check how your charts would look when printed out in grayscale.
If you cannot distinguish color differences, you should change hue and saturation of colors. Seven to 10 percent of men have color deficiency.
Keep that in mind when creating charts, ensuring they are readable for color-blind people. Use Vischeck to test your images. Or, try to use color palettes that are friendly to color-blind people. Donut Charts Essentially, donut charts are pie charts with the area in the center cut out. This makes donuts charts a lot more space-efficient then a pie chart.
Also, cutting out the area in the center makes donut charts de-emphasise the use of area, which makes readers more focused on the length of arcs, instead of comparing the proportions between slices. As you increase the number of segments, the smaller each of them become, until the point they become too densely packed and harder to read or compare.
This is because each part serves as a platform for the next part in the set. Also, like many part-to-whole charts are limited in their data capacity and lose legibility as the number of individual segments increases. Bar charts Bar charts are useful for plotting many data series. Bar charts use horizontal data markers to compare individual values. Area charts Area charts are useful for emphasizing the magnitude of change over time. Stacked area charts are also used to show the relationship of parts to the whole.
Area charts are like line charts, but the areas below the lines are filled with colors or patterns. Point charts Point charts are useful for showing quantitative data in an uncluttered fashion. Point charts use multiple points to plot data along an ordinal, or non-numeric, axis.
A point chart is the same as a line chart without the lines.
Only the data points are shown. Scatter charts Scatter charts are useful for showing relationships between two measures. Scatter charts use colored circles to represent two measures for each dimension.
The x-axis represents one measure, and the y-axis represents a second measure. For example, you create a scatter chart that shows Cost and Revenue by Product. Your scatter chart consists of one circle for each Product. Each Product circle is plotted on the chart based on Cost, on the x-axis, and Revenue, on the y-axis. Bubble charts Bubble charts are useful for showing relationships between three measures. Bubble charts use colored circles of different sizes to show three measures for each dimension.
The x-axis represents one measure, the y-axis represents a second measure, and the size of the bubbles represent a third measure. Your bubble chart consists of one circle for each Product. The size of the circle represents the Quantity Sold for that Product.
