When to Use Charts

Use charts when you want to:

  • Understand trends over time

  • Compare values across categories

  • Identify patterns or anomalies

  • Present query results visually

Charts are created only when you explicitly ask for them.


Requesting a Chart

By default, the Database Assistant returns answers as text.
To generate a chart, include a clear instruction in your request.

Example request:

What are our sales by month? Create a line chart.

The assistant runs the query and generates a chart based on the results.

Once a chart is generated, you can download it as a JPG file for use in presentations, reports, or other documents.



Supported Chart Types

The Database Assistant supports common chart types, including:

  • Line charts – trends over time

  • Bar charts – comparisons across categories

  • Area charts – cumulative trends

  • Pie charts – proportions

  • Scatter plots – relationships between variables

Choose the chart type that best fits the question you are asking.


Example: Comparing Categories

Use bar charts or pie charts to compare categories.

Example request:

What portion of total revenue comes from each product category? Create a bar chart.

This helps visualize how different categories contribute to overall results.


Example: Exploring Relationships

Use scatter plots to explore relationships between metrics.

Example request:

Is there a relationship between order value and purchase frequency? Create a scatter plot.

This can help identify correlations or outliers in the data.


Refining Visualizations

If the chart is close but not exactly what you need, you can:

  • Ask to change the chart type

  • Request a different grouping or timeframe

  • Ask for labels or clearer axis descriptions

Refining the request usually produces better visuals.


Best Practices for Visualisations

  • Ask one question per chart

  • Choose chart types that match the data

  • Specify timeframes and groupings clearly

  • Start with simple charts before adding complexity

These practices help create clearer and more meaningful visuals.
