A sparkline is a small chart inside a worksheet cell. It can't show a full axis or explain its units. It shows the pattern beside the row it describes, without a separate title, axis, or legend. Select the destination cells, then choose Insert > Sparklines. Enter the observations as the Data Range and the empty destination cells as the Location Range.
Line sparklines show a trend through ordered measurements. Column sparklines make individual values easier to compare. Win/Loss sparklines show only direction: a positive value is a win, a negative value is a loss, and a zero has no bar. Their heights don't represent the original magnitudes.
Use one destination cell for each source row. Selecting one extra row or including the header shifts the trends away from their labels. Missing observations leave gaps, while a zero is still a measured value. Markers help readers see individual observations in line sparklines. The tiny chart stays linked to its source, so changing a source cell changes the trend.
