axes not compatible with matplotlib pdf

To use Go language with matplotlib to save figures in PDF format, you need to follow these steps:

  1. Install Go: Go to the official Go website (https://golang.org/) and download the latest stable version of Go for your operating system. Follow the installation instructions provided for your specific platform.

  2. Install the "gonum/plot" package: The "gonum/plot" package is a Go library that provides a set of APIs for creating and manipulating plots. To install this package, open a terminal or command prompt and run the following command: go get gonum.org/v1/plot/...

  3. Import the necessary packages: In your Go code, import the required packages to work with matplotlib and PDF output: go import ( "gonum.org/v1/plot" "gonum.org/v1/plot/plotter" "gonum.org/v1/plot/vg" )

  4. Create a plot: Use the "gonum/plot" package to create a plot and add data to it. Here's an example of creating a simple line plot: ```go p, err := plot.New() if err != nil { panic(err) }

linePoints := plotter.XYs{ {X: 0, Y: 0}, {X: 1, Y: 1}, {X: 2, Y: 0.5}, }

line, err := plotter.NewLine(linePoints) if err != nil { panic(err) }

p.Add(line) ```

  1. Save the plot as a PDF: To save the plot as a PDF file, use the "Save" method of the plot object and specify the output file name with the ".pdf" extension: go err = p.Save(4vg.Inch, 4vg.Inch, "output.pdf") if err != nil { panic(err) }

  2. Run the code: Execute your Go code, and it will generate a PDF file with the plot.

Make sure you have the necessary permissions to write files in the chosen directory. You can modify the code example according to your specific plot requirements.
