Regardless of how many squiggly lines and colorful inserts you provide in your figure, your data might not add more value to the reader. Also, if the figure becomes too cluttered, it can be distracting. Subsequently, the reader might lose interest in your message.Bar charts can obscure the nature of the underlying data when it comes to summarizing continuous distributions. Distributions with different shapes can result in the same summary bar chart, as seen in this chart below from a journal article quoted on twitter.Chart junk is anything that doesn't help you understand the data. If you Google chart junk, you'll come across a million different examples of really bad charts and really bad chart junk.
What are examples of chart junk : Examples of unnecessary elements that might be called chartjunk include heavy or dark grid lines, unnecessary text, inappropriately complex or gimmicky font faces, ornamented chart axes, and display frames, pictures, backgrounds or icons within data graphs, ornamental shading and unnecessary dimensions.
How to avoid chart junk
Follow these principles:
Remove chart borders and backgrounds.
Delete grid lines if they don't add meaningful context.
Only keep legends if your audience needs them to interpret the data.
Don't add images or icons that just decorate your charts without adding info.
Limit the use of table column or row outlines.
Do charts help in trading : Charts are a widely used tool in trading and investing to quickly see the past performance of the stock, the highs, the lows, trends, moving averages, trading volume, and much more. Charts really are the 'footprint of money.
Pies and doughnuts fail because: Quantity is represented by slices; humans aren't particularly good at estimating quantity from angles, which is the skill needed. Matching the labels and the slices can be hard work. Small percentages (which might be important) are tricky to show. Disadvantages
require additional explanation.
be easily manipulated to yield false impressions.
fail to reveal key assumptions, causes, effects, or patterns.
Why is a good chart important
Importance of Charts and Graphs
Charts and graphs are visual representations of data. They are important and useful because they are powerful tools that can be used for things like analyzing data, emphasizing a point, or comparing multiple sets of data in a way that is easy to understand and remember.When a graphic is taken over by decorative forms or computer debris, when the data measures and structures become Design Elements, when the overall design provides Graphical Style rather than quantitative information, that graphic can be called the “Duck”.If you want to show the relationship between values in your dataset, use a scatter plot, bubble chart, or line charts. If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. 5 Steps To Remove Chart Junk In Presentations
Step 1: Remove Special Effects. Remove all the shape effects (bevel/glow/shadow/reflection/soft edges)
Step 2: Use Brand Colors.
Step 3: Delete the Chart Junk.
Step 4: Add a Narative.
Step 5 (Pro Tip): Clean it Up!
How are charts misleading : What are some ways graphs can be misleading Graphs can be misleading if they include manipulations to the axes or scales, if they are missing relevant information, if the intervals an an axis are not the same size, if two y-axes are included, or if the graph includes cherry-picked data.
Can we trade without charts : Yes, it is possible to trade without charts or indicators. In fact, some traders prefer to use a "naked" trading approach, which means making trading decisions based solely on price action, market structure, and support and resistance levels.
How to read a chart like a pro
Legend: If there's a legend (a small box with labels and colors), it tells you what the colors or symbols in the chart mean. For instance, red might represent “Apples” and blue might represent “Oranges.” Data: Now, explore the data (the bars, lines, or points in the chart). Look for patterns, trends, or differences. The pie chart's circularity means the areas lack a common reference point. Pie charts also do badly when there are lots of categories. For example, this chart from a study on data sources used for COVID data visualisation shows hundreds of categories in one pie.Study after study has shown that pie charts are not the most effective means of communicating data. The pie chart's primary limitation is that people are much better at comparing lengths and heights, as you would see in a bar or line chart, than they are at comparing areas within a pie.
How are bar graphs misleading : This is one of the most common way graphs misrepresent data: by distorting the scale. Zooming in a small portion of the y-axis exaggerate a barely detectable difference, and it is especially misleading in bar graphs, since we assume the difference in the size of the bars is proportional to the values.
