"Draw a graph in the programming language Julia" I succeeded in moving the sample for the time being, but the data created by my own program (in Julia language) I decided to find out how to draw a graph using. I made a sample to draw a graph in 3D space. (Refer to the sample of PyQtGraph, the calculation processing part was ported to Julia side) As usual, the calculation result obtained by Julia is displayed as a graph in PyQtGraph. (Please create an environment and move it)
Note: For the environment construction, refer to "Drawing a graph in the programming language Julia".
↑ Drag with the mouse or press the cursor key to rotate the 3D graph. You can zoom in / out by turning the mouse wheel.
