Question 1

What is a line graph?

Accepted Answer

A line graph displays data points connected by straight or curved lines, making it the go-to chart for visualizing trends, changes over time, or continuous data. It's commonly used for sales trends, stock prices, temperature changes, and more.

Question 2

What is the difference between a straight line and a curve line?

Accepted Answer

A straight line connects data points directly with linear segments, clearly showing exact values at each point. A curve line (also called a smooth or spline line) interpolates between points for a smoother appearance, making long-term trends easier to read.

Question 3

How do I enter data for the line graph?

Accepted Answer

Choose 'Combined' mode to enter Label:Value pairs (e.g. Jan:10,Feb:20,Mar:30) in one field, or switch to 'Separate' mode to enter labels (e.g. Jan,Feb,Mar) and values (e.g. 10,20,30) in separate fields. Both modes produce the same chart.

Question 4

Can I download my line graph?

Accepted Answer

Yes — you can export your line graph as PNG, JPG, or SVG. PNG is recommended for websites and presentations. SVG is best if you need to scale the image without quality loss for printing or large-format displays.

Question 5

How do I customize the axis titles and colors?

Accepted Answer

Enter your axis labels in the 'Horizontal Axis Title' and 'Vertical Axis Title' fields. Use the color pickers to set the background color, title color, and font color to match your brand or presentation style.
