What is a compound time series graph?

When two sets of data are compared on the same graph using two lines, it is called a compound time series graph. When two sets of data collected over specific periods of time are compared on the same graph using two lines, it is called a compound time series graph.

What is a series time graph?

Time series graphs are created by plotting an aggregated value (either a count or a statistic, such as sum or average) on a time line. The values are aggregated using time intervals based on the time range in the data being plotted. The following time intervals are used on time series graphs: One decade. Three years.

• Line Graph. A line graph is the simplest way to represent time series data.
• Stacked Area Chart.
• Bar Charts.
• Gantt Chart.
• Stream Graph.
• Heat Map.
• Polar Area Diagram.

What does a time series plot tell us?

A time series plot is a graph where some measure of time is the unit on the x-axis. In fact, we label the x-axis the time-axis. The y-axis is for the variable that is being measured. Data points are plotted and generally connected with straight lines, which allow for the analysis of the graph generated.

What are the three most commonly used graphs?

Types of Charts 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. You would use: Bar graphs to show numbers that are independent of each other.

How do you plot a time series graph?

To construct a time series graph, you must look at both pieces of the paired data set. Start with a standard Cartesian coordinate system. The horizontal axis is used to plot the date or time increments, and the vertical axis is used to plot the values variable that you are measuring.

How do you read a time series graph?

1. Step 1: Look for outliers and sudden shifts. Use process knowledge to determine whether unusual observations or shifts indicate errors or a real change in the process.
2. Step 2: Look for trends.
3. Step 3: Look for seasonal patterns or cyclic movements.
4. Step 4: Assess whether seasonal changes are additive or multiplicative.

What are the four main components of a time series?

These four components are:

• Secular trend, which describe the movement along the term;
• Seasonal variations, which represent seasonal changes;
• Cyclical fluctuations, which correspond to periodical but not seasonal variations;
• Irregular variations, which are other nonrandom sources of variations of series.

Which chart is best for time series data?

line charts
Typically, line charts are the best choice for presenting time series data, but stepped and column charts can also be used as alternatives.

What are the four patterns on the time series graphs?

There are typically four general types of patterns: horizontal, trend, seasonal, and cyclical.
