Conflict between ezplot and linestyle

Running my code I realized that linestyles is not recognized for graphs obtained exploiting ezplot. This issue does not happen for linewidth and for setting the color. Here you see part of the code fig3=ezplot(k-(((tax*a*(inf^esp1)*z)/(demfor))^esp2),[0 300], [0 1]) set(fig3,'color','black','LineStyle', '--','LineWidth',2) The commands color and linewidht are recognized. The curve is drawn but not dashed. Could someone suggest me a solution to the problem?

this is working fine for me

Hi Marco,

I tried reproducing this issue, but it is working normally for me. Please try the following code and see if the problem still persists.

fig = ezplot('x^2 - y^2',[0 300 0 100]);
set(fig,'color','black','LineStyle', '--','LineWidth',2);

If this is not working for you, it might be an issue related to the MATLAB version that you are using. If so, what is the MATLAB version you are using and on what platform (Windows, MAC, or Linux)?

The version of MATLAB matters too. A number of line style problems were fixed in R2014b. Marco may be seeing one of those.

If I run your simplified example in R2014a, I get this:

If I run it in R2015a, I get this:

The R2014a bug we're seeing here had to do with the length of the individual line segments that ezplot was creating. If you zoomed in, you would see that there actually was a line style, it was just getting smeared between adjacent segments. The graphics engine in R2015a does short line segments a bit differently to avoid this problem.
