Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

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.

Bar graphs are best used to compare values across categories. A pie chart is a circular chart used to compare parts of the whole. It is divided into sectors that are equal in size to the quantity represented.

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. Andrew Abela that should help you pick the right chart for your data type.

A comparison chart is a chart that draws a comparison between two or more items on different parameters. You can either compare two items such as in the example below. Image Source. Or, you can use various parameters or comparison points to weigh up two or more items.

Let’s dive into a few of the ground rules when it comes to chart design.

1. Add no more than 7 data snippets to a pie chart.
2. Order your data for a more organized chart.
3. Stick to flat design over 3D design.
4. Use a legend only when necessary.
5. Turn grid view off.
6. Use contrasting colors for each data series.

Create a chart

1. Select the data for which you want to create a chart.
2. Click INSERT > Recommended Charts.
3. On the Recommended Charts tab, scroll through the list of charts that Excel recommends for your data, and click any chart to see how your data will look.
4. When you find the chart you like, click it > OK.

T-Charts are a type of chart, a graphic organizer in which a student lists and examines two facets of a topic, like the pros and cons associated with it, its advantages and disadvantages, facts vs. opinions, etc.

Google chart tools are powerful, simple to use, and free. Try out our rich gallery of interactive charts and data tools.

A T Chart (or T-Chart) is a graphic organizer that separates information into columns, traditionally for comparing. It gets its name from the basic version with two columns: it looks like the letter “T” and is both versatile and commonly used across all subjects.

Y-Chart. Y-Charts are a type of three-part chart, a graphic organizer. For example, a student can use a Y-Chart to help organize what they know about a topic by writing and/or drawing what the topic looks like, feels like, and sounds like.

Ideally, a T Chart can be used in these different ways:

1. Mostly, it is used to compare a topic by providing two different options.
2. You can showcase a before/after or cause/effect scenario using it.
3. It can help you in drawing contrasts and comparisons easily.

Graphic organizers can be categorized in many ways according to the way they arrange information: hierarchical, conceptual, sequential, or cyclical (Bromley, Irwin-DeVitis, & Modlo, 1995).

The main purpose of a graphic organizer is to provide a visual aid to facilitate learning and instruction.

Graphic Organizers are useful educational tools in any subject area. They help students organize their thoughts and ideas for answering questions, function as a pre-writing tool for essays, and provide a visual display of information.

The main purpose of graphic organizers is to make teaching and learning easier, and to improve a student’s understanding of a particular concept.

Graphic organizers are a helpful learning tool for students of all ages to organize, clarify, or simplify complex information—they help students construct understanding through an exploration of the relationships between concepts. Teacher-generated organizers are a useful scaffold to support student learning.

Why Graphic Organizers Work So Well While some approaches like doodling and the mind’s eye strategy apply this theory by having learners create physical and mental pictures of concepts, a graphic organizer keeps the words, but arranges them on a page visually so we better understand how concepts are related.

Though very simple to the eye, graphic organizers are powerful tools, highly instrumental in altering and improving the teaching-learning process in the classroom.
