Examples
- Connect a Line Chart node to an existing node.
- Drag columns onto the x-axis and y-axis.
- Select "Run" to create a line chart with the default settings.
Figure 2: Example line chart with default settings
- The dataframe shown below is used in the remaining examples.
- The dataframe shows fictitious prices of eggs and milk in California, New York, and Texas from 1980 to 2020.
Figure 3: Example input data
- You can group prices by state when charting the data. Drag the "year" column onto the x-axis, and drag the "egg_price" and "milk_price" columns onto the y-axis and the additional series section.
- Select "state (String) from the auto-populated dropdown menu in the "Group Y axis by" field.
- Select "Run" to create a line chart.
- Notice that the resulting line chart has egg and milk prices over time grouped by state.

- Select all "egg_price" labels in the legend to temporarily remove them from the visualization.
- This makes it easier to examine only certain lines on the plot.
