Angular Line Charts are plotted by connecting adjacent datapoints with a line - works well for either large or small number of data points. Line Charts are generally used to show the trends, historical data or to compare two different data sets. Angular Chart Component allows you to customize charts with smooth-curved lines called Spline Chart or with staircase shaped lines called Step-Line Charts. You can easily switch between these chart-types by changing type property in dataseries.
Markers are generally shown for all the datapoints when there are less number of datapoints & it's hidden when the number of datapoints are large. Markers can even be added to individual datapoint to highlight it - this is helpful in showing a spike in traffic, price, etc. A set of datapoints can even be highlighted by changing the color of connecting line between those datapoints. Graphs also supports features like zooming / panning, exporting chart as image, animation, etc.
Line Charts (also referred as Line Plot or Line Graph) are drawn by connecting adjacent datapoints with a straight line.
Spline Charts are also called as Smooth Curved Line Chart as the line connecting datapoints have smooth curves.
Step Line Charts are also known as step charts & sometimes staircase chart because of it’s shape.
Most commonly used features in Angular Line Chart includes zooming, panning, customizing color, thickness & dash-type of the line, adding markers, etc.
In most of the cases Angular Line Charts render faster with default options of the library when you have datapoint in the range of 100,000. However, if you are rendering very large number of datapoints, there are few tweaks that you can do in order to make the chart render faster.
