How do I choose a graph?
Bar charts are good for comparisons, while line charts work better for trends. Scatter plot charts are good for relationships and distributions, but pie charts should be used only for simple compositions — never for comparisons or distributions.The four basic graphs used in statistics include bar, line, histogram and pie charts.Ask yourself how many variables you want to show, how many data points you want to display, and how you want to scale your axis. Line, bar, and column charts represent change over time. Pyramids and pie charts display parts of a whole. While scatter plots and treemaps are helpful if you have a lot of data to visualize.

How to choose visualization : How to Choose the Right Visualizations

  1. Tabular format is best used when exact quantities of numbers must be known.
  2. Line charts are best used when trying to visualize continuous data over time.
  3. Bar charts are best used when showing comparisons between categories.
  4. Pie charts are best used to compare parts to the whole.

How to read a graph

  1. Determine the type of graph.
  2. Read the title or legend.
  3. Examine any other text.
  4. Identify the variables on the axes and what they represent.
  5. Observe the x-axis and y-axis.
  6. Determine what each number on the graph means.
  7. Identify patterns in the data.
  8. Find where your data falls on the graph.

What should a graph look like : A graph with a simple design strives for a clean, uncluttered look. Simplicity in design does not mean simplicity in data however; well-designed graphs can represent rich data. Avoid distortions, shading, perspective, volume, unnecessary colour, decoration or pictograms, and 3D.

How to decide which plot to use

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. If you want to compare volumes, use an area chart or a bubble chart.When describing graphs, start by recognizing the main patterns, trends, or relationships they show. For example, if the chart clearly shows an increase in revenue over the past year, you should highlight that first.Line Chart

The result is a simple, straightforward way to visualize changes in one value relative to another. But line charts aren't limited to time. Any dimension—like date types, time intervals, and other ordinal data—can be used as the horizontal axis.

Five principles of good graphs

  1. Show the data clearly. Showing the data clearly includes ensuring the data points can be seen but also providing meaningful text on the graph itself.
  2. Use simplicity in design of the graph. A graph with a simple design strives for a clean, uncluttered look.
  3. Use alignment on a common scale.

How to tell if a graph is good or bad : Graphs are often made misleading for advertising or other purposes, or even just by accident, by: • Leaving gaps/changing the scale in vertical axes • Uneven shading/colours • Unfair emphasis on some sections • Distorting areas in histograms (bar widths should always be equal – if you have different widths then the bar …

How to design a good graph : Good graph design

  1. Don't put too much data on one chart; use small multiples (same format, same scale)
  2. Use one measure per chart.
  3. Remove unnecessary borders, backgrounds and grid lines.
  4. Default orientation should be landscape.
  5. Avoid distracting graphics or animations.

How do you find the right graph

For example, if you want to show a trend over time, a line chart or an area chart might be more appropriate. If you want to compare data points, a bar chart or a column chart might be a better choice. If you want to show a distribution, a histogram or a box plot might be more useful.

Graphs should always have at minimum a caption, axes and scales, symbols, and a data field. Plotting symbols need to be distinct, legible, and provide good contrast between the figure in the foreground and the background.How to Choose the Right Visualizations
