A line chart is a statistical graphic that displays information as a series of data points connected by straight line segments. It is suitable to represent dependency of one parameter from another. In the following example we see dependency of price from time.


Line charts in Arbometa

In Arbometa line chart is a preview action for a node. If you have your own data (like metal prices in the current example), you can create a node, choose line chart as a preview, decide what field will represent X-axis and what field Y-axis and get a chart with your data easily.

How we made this example

1. We've created a node "Metal prices" with 3 fields: metal, date and price. How to create a node.
2. Added a preview of line chart type to the node.
3. We had a file with data in CSV format (CSV format represents data as a table - you can open it in Excel, for example). Every row in the file contained information about one price of one metal at the particular date.
4. Created an import (imports explained).
5. Automatically generated programming code.
6. Imported data from the file.
