A Line Chart is created by connecting a series of data points together with a line. This popular chart type is useful when you want to show data trends. Line charts are used to show how two parameters are related to each other or to display how one variable changes effected by another. The Line charts are very useful as a comparison tool as well. The Line charts components from the ElegantJ Charts Library are a preferred choice for keeping an eye on important business metrics as the patterns of a Line Chart are eye catching.
Line charts can be used for:
Determining trends or cyclical variations
Money distribution over time
Production over time
Price variation over time
Environmental changes over time
Material characteristics by temperature
Clinical response by concentration
Components and functions of Line Charts:
A line connects data items in a Line Chart in the same series of other lines to form and display
a trend in your data over a number of data categories.
In a Line chart, points or symbols represent data items.
A Line chart component consists of two axes, a vertical or Y-axis and a horizontal or X-axis.
The categories of data become the scale indexes along the X-axis, while an individual line
represents each series of data.
Generally, the X-axis represents time and the Y-axis represents value.
Points are plotted on a Line Chart for each time interval and these points are joined by a
line as a visual representation of change in data with timeline.
The X-axis does not necessarily have to represent time. It can also represent other data types.
The only requirement is that there has to be some relationship between the X and Y-axis.
By plotting multiple series of data on the same grid, it becomes very easy to compare the data sets.
Line chart components can be used to display a wide variety of data and relationships.
For each line in the Line chart, the following statistics can be calculated:
Sum: The sum value in the series.
Count: The count value in the series.
Valid Count: The valid count value in the series.
Average: The average value in the series.
Valid Average: The valid average value in the series.
