Streamline Vector Plot

A Streamline plot is a representation based on a 2-D vector field interpreted as a velocity field. Origin starts to support this new graph type in version 2020b. In this blog,  we are going to generate a streamline graph of the vector field {vx,vy} as a function of x and ywhere  v= cos(x^2+y) , and vy = x-y^2+1.

1.   Click New Matrix button from tool bar to create a new matrix. Right click on the upper left corner to select Set Matrix Dimension/Labels… from flyout menu.  Set matrix dimension to 100X100. Set x,y From and To values to be -3 and 3.

2.  We next prepare two matrix objects to save  vx,vy values.  Click on the yellow  D icon and add a second matrix object. 

3.  Right click on each matrix object and select Set Matrix Values...  Enter cos(x^2+y) in formula entry for first object, and x-y^2+1 for second object.

4.  Select from menu Plot:Specialized:Streamline to make the plot.  Customize the graph further to get the final result. Please also download the project file.

  1. Hi there,

    I’m trying to do this in Origin2020 but there isn’t a “specialized” tab in my “plot” tab… Is this feature still available?
