What file formats does ChartGen.ai support?

ChartGen.ai supports CSV files (.csv) and Excel files (.xlsx, .xls). You can also paste data directly into the interface. The AI automatically detects column types, dates, and numeric values to make chart creation seamless.

How does ChartGen.ai compare to Excel charts?

ChartGen.ai is faster and easier than Excel for creating charts. While Excel requires manual chart configuration and formula knowledge, ChartGen.ai uses AI to automatically select the best chart type, configure axes, and apply professional styling.

How does ChartGen.ai compare to Tableau?

ChartGen.ai is a free, instant alternative to Tableau for simple chart creation. While Tableau is a powerful enterprise BI platform requiring licenses and training, ChartGen.ai offers zero learning curve and instant results. It's perfect for quick visualizations without the complexity of dashboard setup.

Is my data secure when using ChartGen.ai?

Yes, data security is a top priority. Your uploaded files are processed in real-time and are not permanently stored on servers. All data transmission is encrypted using HTTPS, and ChartGen.ai is SOC 2 compliant for enterprise use. Your data is never shared with third parties.

What is the best chart type for comparing data?

Bar charts are the best chart type for comparing values across categories. Use horizontal bar charts when category names are long, and vertical bar charts for time-based comparisons. ChartGen.ai's AI can automatically recommend the best chart type based on your data structure.

What chart should I use to show trends over time?

Line charts are ideal for showing trends over time and continuous data changes. Use area charts if you want to emphasize volume or cumulative totals. ChartGen.ai can create both types and will recommend the best option based on your data.

When should I use a pie chart?

Use pie charts to show part-to-whole relationships when you have 2-5 categories that sum to 100%. Avoid pie charts for more than 7 categories or when comparing similar values. ChartGen.ai will suggest alternatives like bar charts if your data isn't suitable for pie charts.

What is a line chart and when should I use one?

A line chart is a data visualization that displays information as a series of data points connected by straight line segments. It's ideal for showing trends over time, continuous data, and comparing multiple data series. Use line charts when you want to emphasize the rate of change between data points or visualize time-series data.

How do I create a line chart with ChartGen.ai?

Creating a line chart is simple: 1) Upload your data file (CSV, Excel, or JSON), 2) Select 'Line Chart' from the chart types, 3) Describe what you want to visualize in natural language (e.g., 'Show monthly revenue trend'), and 4) Click Generate. Our AI will automatically configure the optimal line chart for your data.

What data formats are supported for line chart generation?

ChartGen.ai supports CSV, Excel (.xlsx, .xls), and JSON files. For line charts, your data should ideally have a time or sequential column (for the x-axis) and one or more numeric columns (for the y-axis values). The AI automatically detects column types and suggests the best configuration.

Can I create multi-line charts to compare different data series?

Yes! Simply include multiple numeric columns in your data, and ChartGen.ai will create a multi-line chart with each series displayed in a different color. You can compare trends across products, regions, or any other categories on the same chart.

How do I customize the appearance of my line chart?

You can customize colors using our 12 pre-designed themes or the color picker. In your prompt, you can also specify preferences like curved vs. straight lines, adding data points, showing/hiding gridlines, and more. The AI interprets your natural language instructions to style your chart.

What's the difference between a line chart and an area chart?

A line chart shows data points connected by lines, while an area chart fills the space between the line and the x-axis with color. Area charts are better for emphasizing the magnitude or volume of values, while line charts focus on the trend and rate of change. ChartGen.ai can create both types.

Can I add markers to data points on my line chart?

Yes, you can enable data point markers in your line chart. Simply mention 'add markers' or 'show data points' in your prompt, and the AI will add circular markers at each data point for better visibility and precision reading.

Is ChartGen.ai part of Ada.im?

Yes! ChartGen.ai is a core product capability of Ada.im, an AI-powered data analysis platform. While ChartGen.ai focuses on chart generation, Ada.im offers additional features like data connectors, team collaboration, interactive dashboards, and automated reporting.

Can I export my line chart?

Yes, you can export your line chart as a PNG image for presentations, reports, or sharing. The export maintains high quality and includes all your customizations. For additional export formats and enterprise features, check out Ada.im.

How do I handle missing data points in my line chart?

ChartGen.ai intelligently handles missing data. You can choose to skip gaps (resulting in disconnected line segments), interpolate values (connect with estimated points), or show as zero. Specify your preference in the prompt, or the AI will choose the most appropriate method based on your data type.
