Notice that each line is a different color.

The Line Chart is equally effective in displaying trends for multiple series as shown in the above Line Chart without markers.

Markers-the circles, squares, triangles, or other shapes which mark the data points-are optional, and Excel displays a unique marker in shape and/or color for each data series. The first image shows the Line with Markers chart of our single data series. The vertical axis (Y-axis) always displays numeric values and the horizontal axis (X-axis) displays time or other category. The Line Chart is especially effective in displaying trends.
