How to Create a Time Series Graph in Excel

Introduction to Time Series Graphs

A time series graph displays data points over a specified time interval, allowing trends and patterns to be observed. This tutorial covers the creation of a time series plot in Excel, using USGS streamflow data as an example.

Preparing Your Data

Ensure your time series data is already imported into Excel. The data should be arranged in two columns, with the time data in one column and the data series you wish to plot in the adjacent column.

Creating the Time Series Plot

To create the time series graph, select both the time (DateTime) and data series columns. Click on the 'Insert' ribbon and choose 'Scatter'. For streamflow data, use a smooth scatter plot to depict long-term trends or hydrographs for individual events. If working with precipitation data, opt for a column plot to represent the data accurately.

Customizing the Graph

After inserting the scatter plot, you can customize it by adding chart elements such as titles, axis labels, and legends to enhance readability and interpretability. Adjusting the line style to 'smooth' will provide a clearer visual representation for streamflow time series data.

Finalizing Your Time Series Graph

Review your time series graph for accuracy and clarity. Make any necessary adjustments to the layout or style to convey the time series data effectively. Once satisfied, your Excel time series graph is complete and ready for presentation or analysis.
