## What are the types of chart?

There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things.

**What are the parts of a chart?**

Chart ElementsThe title is a text box you can place anywhere on the chart.The plot is the area on the chart that displays the data in the chart type you choose.A data point is one piece of data appearing on the chart. A chart’s legend shows what kind of data is represented in the chart. Series are sets of related data.

### What should a graph title include?

The title should be a concise description of what is being graphed (e. g., “Pressure as a Function of Temperature for Nitrogen”). Usually you do not need to describe in the title the units used in the graph, but there are some instances where this is necessary.

**Do all graphs need a title?**

Graphs are used to present data. They must be clearly labelled if the reader is to understand them. By labelling we are referring to the text inside the graph itself, and not the title. This graph also has a legend, which provides more information.

## What is the first thing you should read when interpreting a graph?

The first part is the title. A graph title will tell you what the graph is about, and without it, the graph will probably make very little sense. Graph titles should be short and to the point, and not creative the way a short story title might be. In addition to a title, most graphs have an x- and y-axis.

**How do you read a trend in a graph?**

The y-value of each point generally increases as the x-value increases. We can add a trend line to this graph by adding a line that goes through the middle of the points. Notice that the trend line has a positive slope. This matches the positive correlation of our scatter plot.

### How do you read trends?

Complete the following steps to interpret a trend analysis….Step 1: Determine whether the model fits your data. Examine the trend analysis plot to determine whether your model fits your data. Step 2: Compare the fit of your model to other models. Step 3: Determine whether the forecasts are accurate.
