How to create a Line Chart

In this blog, we will learn how to create a Line Chart/span> in the open source BI product Helical Insight.

To create a Line chart in Helical Insight, you need at least one dimension and one measure. In this example, the dimension booking_platform is placed in the Columns section and the measure sum_travel_cost is placed in the Rows section. After selecting the Line option under the Chart section in the Visualization panel, the system generates a line chart.

Each point on the line represents a booking platform (Agent, Makemytrip, Website), and the position of the point on the Y-axis indicates the total travel cost for that platform. The line connects these points, making it easy to compare values and observe variations across booking platforms.

How to create a Line Chart

Using Color (Marks Section) – Creating Multiple Lines

By default, a single line is displayed.

To split it into multiple lines:

  • Drag the dimension mode_of_payment into the Color option under the Marks section.

This automatically creates multiple lines within the same chart — one line for each payment mode (Cash, Cheque, Credit, Net Banking). Each colored line shows how travel cost varies across booking platforms for a specific payment mode.

This helps compare trends between different payment methods in a single visualization.

Line Chart Created using “Chart” Category:

A Line chart created using chart category can have one dimension in the columns, one measure and a dimension/measure in the colors section.

It will not be able to support multiple dimensions in rows and columns.

Grid Style Line Chart – Grid Chart Section

A line chart created using Grid chart category is highly flexible. It can allow users to drag any number of dimensions in both rows and columns, and accordingly it creates a sort of matrix within which the line chart gets populated. Thus it is much more flexible.
