How do I know what graph to use?
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.If the independent and dependent variables are numeric, use line diagrams or scattergrams; if only the dependent variable is numeric, use bar graphs; for proportions, use bar graphs or pie charts.You would use:

  1. Bar graphs to show numbers that are independent of each other.
  2. Pie charts to show you how a whole is divided into different parts.
  3. Line graphs show you how numbers have changed over time.
  4. Cartesian graphs have numbers on both axes, which therefore allow you to show how changes in one thing affect another.

What should you look for in a graph : Check the data points plotted can be detected, and are not covered up or obscured. Don't assume the viewer is a mind-reader … label titles and axes clearly and accurately. Maintain constant measurement scales and avoid distortions.

What is the most common graph to use

1. Bar chart. A bar chart, also known as a horizontal column chart, is popular for a reason — it's easy on the eyes and quickly visualizes data sets. With bar charts, you can quickly identify which bar is the highest or the lowest, including the incremental differences between bars.

What is the best graph to use to compare this data : Bar graphs can help you compare data between different groups or to track changes over time. Bar graphs are most useful when there are big changes or to show how one group compares against other groups.

Types of Graphs in Statistics. The four basic graphs used in statistics include bar, line, histogram and pie charts.

How do you name a graph

Your title should be short, but still clearly tell what you have graphed. The most common and recommended way to name your graph is to say what your "y" (vertical) and "x" (horizontal) axis are.Tips for reading charts, graphs & more

  1. Identify what information the chart is meant to convey.
  2. Identify information contained on each axis.
  3. Identify range covered by each axis.
  4. Look for patterns or trends.
  5. Look for averages and/or exceptions.
  6. Look for bold or highlighted data.
  7. Read the specific data.

Essential Elements of Good Graphs:

  • A title which describes the experiment.
  • The graph should fill the space allotted for the graph.
  • Each axis should be labeled with the quantity being measured and the units of measurement.
  • Each data point should be plotted in the proper position.
  • A line of best fit.


The axes do not need to start at zero. For example, if all the x values occur between 400 and 600 nm, a graph of these data could start at 400 nm. The key to preparing good graphs is selecting a scale that shows all of the data and minimizes large regions of blank space.

What is the easiest graph to use : Bar Graphs

The simplest and most straightforward way to compare various categories is the classic bar graph. The universally-recognized graph features a series of bars of varying lengths. One axis of a bar graph features the categories being compared, while the other axis represents the value of each.

What is the best graph for population : Bar graphs probably the most versatile way of displaying population data. They are often used to show population growth over time but they can also show things such as the relative proportions of different groups in the society or they may be used to compare populations of different places.

When to use which 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.


Following are the best comparison graph trusted by industry experts for effective data visualization:

  1. Pie Chart.
  2. Bar Chart.
  3. Histogram.
  4. Line Charts.
  5. Doughnut Chart.
  6. Overlapping Area Chart.
  7. Combo Chart.
  8. Understanding Data Type.
  • Bar graphs are typically used to compare quantities of different categories in data. They are great for comparing categorical or nominal data where the categories are distinct and don't overlap.
  • Line graphs, on the other hand, are used to show a trend over time, also known as a time series.

When should you use a histogram : When you should use a histogram. Histograms are good for showing general distributional features of dataset variables. You can see roughly where the peaks of the distribution are, whether the distribution is skewed or symmetric, and if there are any outliers.
