Previous literature has found that the two most frequently used plot types – bar charts and dot and whisker plots – are a poor way to represent data because they only show the summary statistics of data, not their distribution, potentially hiding important information. 2.Here are the issues with the bar chart compared to the Jitter Plots (right).
The bar chart has zero uncertainty built into it – i.e. spread and variance around the mean is missing.
Bar charts are asymmetric and have a within bar bias because all the “ink” is between 0 and the average.
Avoid using bar graphs overlayed on a map to show geospatial information, unless the chart has enough space to show the entire bar for all bars. Otherwise, this can lead to occlusion, where some bars hide shorter bars behind them, like in this chart showing the populations of the 100 biggest cities in the world.
What makes a good bar chart : Best practices for using bar charts
Use a common zero-valued baseline.
Maintain rectangular forms for your bars.
Consider the ordering of category levels. One consideration you should have when putting together a bar chart is what order in which you will plot the bars.
Use color wisely.
Common misuses.
What is the main limitations of bar chart
Lack of degree of details: Only major activities are shown in bar chart and sub-activities can not be separated out. Hence effective control over the activities in big projects can not be achieved. A bar chart does not show progress of work and hence it can not be used as a control device.
What should a good bar chart have : The frequencies need to be labelled on the vertical axis in equal intervals. The bars need to have equal gaps between them as it is representing discrete data. The bars need to be of equal width. The chart needs a title.
Five Easy Ways to Improve a Bar Chart
Sort the bars in descending or ascending order.
Rotate the chart.
Avoid double-encoding.
Speaking of double-encoding, color carefully.
Remove chart junk.
Here are 8 steps to turn a default bar chart into a professional looking bar chart.
Arrange the bars in ranked order.
Increase the ratio of bars to background.
Remove the legend.
Add data labels and remove gridlines.
Clean up the axes.
Add text that explains the message.
Increase font sizes so they are easy to read.
What are the disadvantages of charts
2 Disadvantages of graphs and charts
They can also create bias or distortion, as you can manipulate the data or the visual elements to emphasize or hide certain aspects. Graphs and charts can also distract or overwhelm your readers, if you use too many, too complex, or too colorful ones.When to avoid bar charts:
Summarizing continuous data. Bar charts can obscure the nature of the underlying data when it comes to summarizing continuous distributions.
Long time series.
Correlation.
Geospatial information.
Bar chart basics: dos and don'ts
Start y-axis at zero.
Correct spacing.
Include context where necessary.
Use color to enhance insights.
Sort categories for clarity.
Avoid breaking long bars.
Avoid clutter.
Don't skip values.
When you are plotting date-based data, you may find that the bars in your chart are very narrow. The solution for this is to click the Excel chart's X axis, right click and choose Format Axis. Select Axis Options and then click on Text Axis to select it. This changes the way the axis is plotted giving wider bars.
What is the limitation of bar charts : Limited scope for multivariate data: Bar charts can only display one or two variables at a time, making them less useful for displaying multivariate data. In such cases, a scatter plot or heat map may be more appropriate.
What are 4 common mistakes made when making a graph chart :
1 Choosing the wrong type of display. One of the first decisions you have to make when creating a graphical display is what type of display to use.
2 Using too many elements.
3 Misusing scales and axes.
4 Ignoring design principles.
5 Not checking for errors.
6 Not testing for clarity.
7 Here's what else to consider.
What are the rules of bar charts
Bar Charts
A pair of axes.
The frequencies need to be labelled on the vertical axis in equal intervals.
The bars need to have equal gaps between them as it is representing discrete data.
The bars need to be of equal width.
The chart needs a title.
In almost all cases, a bar chart value axis should start at zero and finish just above the maximum value in your dataset. This is what they're built for: large rectangles, filling the available space, making comparisons easy and obvious.Five Easy Ways to Improve a Bar Chart
Sort the bars in descending or ascending order.
Rotate the chart.
Avoid double-encoding.
Speaking of double-encoding, color carefully.
