Embedded chart vs. Chart sheet
In Microsoft Excel and other spreadsheet programs, there are two types of charts: an embedded chart and chart sheet. An embedded chart is a chart object that can be inserted into a worksheet. A chart sheet is a chart that is a sheet of its own.
To insert an embedded chart, use the Insert option in the spreadsheet program you have available to you.
To insert a chart sheet, right-click on the worksheet tabs at the bottom of the worksheet and click Insert, then Chart.
