Hey all,  
I am trying to plot a graph on Julia, and the plot is being done but I don’t see the axes, nor the title or legend, all I get is the following message:

GKS: Rectangle definition is invalid in routine SET\_VIEWPORT

and the plot itself looks like this:

The plotting is of some complex function which I took only the real part.  
Does anyone knows and can help ?  
thanks for all the helpers!

That looks like a lot of points. I would try to take a smaller sample (lets say every 100th point)

The issue with the points is not the problem, I already tried to take a fewer points.

`GKS: Rectangle definition is invalid in routine SET_VIEWPORT`

That usually happens when handling huge values (close to `Inf`), or trying to plot invalid values (negative or zeros in logarithmic scales, …).

If you need help, you need to provide more information on the data plotted, or even better provide a `MWE`.

The arguments are valid, I already checked them based on the same error other people got.  
I think I solved that by moving to the Plotly backend

That’s not what I’d call `solving` a problem (bug fixes could benefit to other users).  
But good anyway that another backend suits your needs.
