Before delving into the how-to guide, we’ll address the following question: what is a Time Series Chart?

What is a Time Series Chart?

Definition: A Time Series Chart (also called a Time Series Graph) is a visualization design that illustrates data points at successive intervals of time.

Each point in a Time Series Chart in Excel corresponds to a time and variable under study. The horizontal axis of the chart or graph plots time increments while the vertical displays the key data point understudy.

Types of Time Series Chart in Excel

There’re 4 types of Time Series Chart in Excel, namely:

1. Dual Axis Line Chart
2. Multi-Axis Line Chart
3. Sentiment Trend Chart
4. Area Line Chart

Let’s discuss these charts in detail.

1. Dual Axis Line Chart

A Dual Axis Line Graph is one of the best Time Series Graph example for comparing two data sets for a presentation.

The visualization design uses two axes to easily illustrate the relationships between two variables with different magnitudes and scales of measurement.

The relationship between two variables is referred to as correlation. The Dual Axis Line Chart illustrates plenty of information using limited space, so you can discover trends you may have otherwise missed.

1. Multi-Axis Line Chart

Plotting multiple metrics in one graph is possible if you use a Multi-Axis Line Chart.

This chart visualizes trends and relationships in various datasets. And it’s made up of various data points connected using line segments, where each point represents a single value. Use this chart to visualize continuous data like prices over time.

1. Sentiment Trend Chart

A Sentiment Trend Chart is one of the Time Series Chart in Excel you can use to display the target market’s opinion of your offerings.

The chart is a must-have, especially if your goal is to show the growth and decline of key variables. The line curve in the chart shows the overall pattern and trend of a key variable over a specified period.

1. Area Line Chart

An Area Line Chart is a visualization design that uses a line graph and a filled area to display patterns and trend insights into key data points in a specified period.

The visualization design is ideal if your goal is to display trends. Besides, it’s one of the best charts for tracking performance in a specified period.

The visualization design is amazingly easy to read and interpret. Furthermore, its minimalist design ensures no insight is obscured.

In the coming section, we’ll address the components of a Time Series Chart in Excel.

Components of a Time Series Chart in Excel

1. Trend component

Analyzing trends is critical in predicting future movements.

The trend shows an increase or decrease of a key variable over a certain period. Not all increases or decreases occur simultaneously.

1. Seasonal Component

This is the variation in a particular variable due to some predetermined patterns over time.

You can use Time Series Chart in Excel to display insights into the commodity price quotes, interest rates, exchange rates, stock prices, and so on.

In the coming section, we’ll address the following question: why should you use the Time Series Chart?

Why Should You Use the Time Series Chart?

Use Time Series Chart in Excel to display changes in metrics (plotted on the vertical axis) and continuous values, such as time (plotted on the horizontal).

To get the insights, check for line segments moving consistently from left to right and evaluate their respective slopes (rate of change).

On the horizontal axis, use a variable that depicts continuous attributes at regular intervals of measurement. And this variable should be a temporal one, generating an observation every minute, hour, day, week, or month.

Use a variable in each of the intervals defined by the horizontal-axis variable on the vertical axis. Often, this can be a statistical summary, such as:

• Count
• Average

FAQs:

What chart is best for displaying time series?

There’re 4 key charts you can use to display time series insights. And they include:

1. Area Line Chart
2. Dual Axis Line Chart
3. Multi-Axis Line Chart
4. Sentiment Trend Chart

The charts mentioned above are incredibly easy to read and interpret. Besides, they’re easy to plot if you use third-party add-ins, such as ChartExpo.

When should you use a Time Series Chart?

Use Time Series Chart in Excel to display changes in key variables (plotted on the vertical axis) and continuous data points, such as months (plotted on the horizontal).

To get the insights, check for line segments moving consistently from left to right and evaluate their respective slopes (rate of change).

Wrap Up

You have data you’ve been tracking over time.

And you’re tasked to explain its trend and, most importantly, provide a forecast.

What’s the go-to chart?

Yes, you guessed right. It’s the Time Series Chart. The chart is suitable in this scenario because time and dates are continuous, categorical data.

If you want to craft a compelling data story that provides actionable insights into trends, outliers, and other shifts, use Time Series charts. And this is because they’re straightforward to read and understand. Remember, simplicity is always at the core of every persuasive narrative.

There’s no doubt that a majority of us don’t like to be subjected to cognitive overload. So, the simpler the message, the more compelling it becomes.

What is a Time Series?

A time-series represents a collection of observations obtained through repeated measurements. Usually, these are in successive order. Time series data can come from anywhere. As long as the data is quantifiable over time, it can be a part of a time series. Time series analysis is prevalent in many fields, especially finance.

A time series can come from any variable that changes over time. In finance, investors may use it to keep track of a security’s price over a period, whether short or long. The details of a time series may differ according to the available data or the needs of investors.

What is a Time Series Analysis?

Time series analysis is useful in measuring the variation in a dataset over a specific time. Essentially, time series analysis involves the study of data collected in a time series. The objective of this type of analysis may differ according to the users’ needs. Usually, however, time series analysis is prevalent for identifying patterns and trends.

Time series is crucial for finance and investing. However, it also has applications in other fields, such as economics. The process for time series analysis in other fields is similar. Whenever users have a data set with historical values, they can analyze it to identify any associated patterns and predict future positions. However, there might be some limitations that may come with it.

How to perform Time Series Analysis in Excel?

As mentioned, if investors have a data set that records values at certain intervals, they can perform a time series analysis. They can use Excel to perform a time series analysis with their given data set. It is possible to use Excel in analyzing any given set as long as the data is quantifiable.

For example, a company, Red Co., has the following profits over some years.

The data in the above table consists of Red Co.’s annual profits for eight years. It is possible to perform time-series analysis on the data in Excel through charts. The best option for this analysis is by using a line chart. It is available under the “Insert” tab and “Charts” section.

The line chart will appear like below.

From there, it is possible to enable a trendline using the “Design” tab under “Add Chart Element”. Within the dropdown, the option is available in the “Trendline”. The chart will look as below.

That is the line that shows the trend for the data. However, users can use the trendline feature to extrapolate the data. The option is available under the same “Trendline” list but choosing “More Trendline Options”. A new tab will open that looks as below.

Using the forecast feature under those options, it is possible to go forward and backward using the given data. For example, a chart that forecasts three periods in the future will look as follows.

Users can also choose other types of trend lines, such as Moving Average for further analysis.

Conclusion

A time-series represents a sequence of a quantified dataset in successive order. Time series analysis a tool used to measure the change in a dataset over a specific time. It is possible to perform time series analysis in Excel with the help of charts and trendlines. Users can also use it to extrapolate the data into future periods.
