What type of chart has only one data series?

To chart a single data series, such as sales in one region, use a pie chart. Compare positive and negative values.

How do I show only one data label in Excel?

Click the data label with the text to change and then click it again, so that it's the only data label selected.

Which chart is optimal for single series of data usage?

Bars (or columns) are the best types of graphs for presenting a single data series. Bar charts have a much heavier weight than line graphs do, so they really emphasize a point and stand out on the page.

Which chart type should be used to present data across a period of time?

Line charts are the best when you want to map continuous data over a period of time. For example, a traffic increase over a period of time, a weather report, an increase in sales, etc. Line graphs should be used to identify spikes in traffic.
