Question 1

How do I save a plot as an SVG file with Gonum Plot?

Accepted Answer

Use the vg package to create an SVG writer—after drawing the plot, call the Save method with desired dimensions. The godoc provides examples for different backends like SVGo or EPS.

Question 2

Is Gonum Plot better than using a Python library like matplotlib for Go projects?

Accepted Answer

For Go-native applications, Gonum Plot avoids language interoperability issues and leverages Go's performance, but matplotlib has more features and a larger community. Choose based on your team's expertise and project integration needs.

Question 3

How to add error bars to a line plot in Gonum Plot?

Accepted Answer

Use the plotter package's error bar functions: create an error bar plotter with your data and add it to the plot alongside the line plotter. Check the plotter package documentation for specific methods like NewErrorBars.

Question 4

Can I use Gonum Plot for real-time data visualization?

Accepted Answer

It's possible but not ideal—Gonum Plot is designed for static plots, so real-time updates require regenerating and redrawing plots, which can be inefficient compared to libraries built for interactivity.

Question 5

How to install Gonum Plot with Go modules?

Accepted Answer

Run `go get gonum.org/v1/plot/...` in your project directory; it will be added as a dependency in go.mod. Ensure you have Go modules enabled for seamless integration.
