CustomizabilityLine charts allow you to customize colors of individual markers that lets you highlight a particular data point from the rest. This is useful in showing a spike in the traffic, prices, etc. You can also control various other aspect like line thickness, order of rendering, etc. You can selectively zoom & pan into a certain region to get a better picture when there are large number of data points.
Multi Series Line ChartsIn case of a multi series line chart, each series is automatically assigned a color based on the selected theme. But you can customize the same by overriding color property of any series or data point. Observe that the ToolTip sticks to the line once hovered upon and then then the line is tracked automatically – you need not have to follow every data point closely.
