Bar graphs to show numbers that are independent of each other.
Pie charts to show you how a whole is divided into different parts.
Line graphs show you how numbers have changed over time.
Cartesian graphs have numbers on both axes, which therefore allow you to show how changes in one thing affect another.
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.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.
How to create an effective graph : Five principles of good graphs
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.
Use simplicity in design of the graph. A graph with a simple design strives for a clean, uncluttered look.
Use alignment on a common scale.
How to understand graphs
How to read a graph
Determine the type of graph.
Read the title or legend.
Examine any other text.
Identify the variables on the axes and what they represent.
Observe the x-axis and y-axis.
Determine what each number on the graph means.
Identify patterns in the data.
Find where your data falls on the graph.
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.
If you've got lots of data or the differences within your data are subtle, a series of bar charts would be a better choice. Basically–bar charts are the most reliable method when it comes to showing percentage changes and visualizing comparisons. clustered bar chart
To graph three variables, the best choice is clustered bar chart. We can graph three variables using many programs such as Excel, power point etc. A line graph is a graphical representation of data that changes over a period of time. It consists of a horizontal x-axis and a vertical y-axis.
Which is the first key point to choosing a chart is
The first is identifying your idea or message.
It is important to keep in mind that the primary purpose of a chart is to present quantitative information to an audience. Therefore, you must first decide what message or idea you wish to present.A bar chart (or bar graph) is the simplest chart type for comparing different categorical data. You can create visually appealing bar charts that can be plotted both horizontally or vertically.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. 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.
Which graph is easy to understand : 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.
What is the easiest graph to read : Bar charts are great for comparison. The differences in bar length are easier to perceive, than, for example, differences in size and color. Bar charts are commonly used charts due to their simplicity. Viewers mostly need to decode their bars' length and position, making bar charts very easy to understand.
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. Selecting an effective data visualization
Consider the characteristics of your data.
Define your audience. Accessibility.
Select the best visualization for your data. Cartesian charts. Pie and donut charts. Progression charts. Text and tables. Maps. Other charts.
A bar chart is especially useful with comparing two sets of data.
