Poor imshow image quality

Hi I am trying to get a figure into a plot using imshow nd the results I get are really poor quality

this is the original figure:

this is what I get:

Increasing the size of the figure, does make the quality slightly better but it is still not any close to the original

the code I ued is:

imshow('Truss.png','border','tight','InitialMagnification',200)

I used border tight, and initial magnification but they dont seem to change anything all, with respect the size and quality

any help is appreciated

thanks

The image is drawn over a TiledChartLayout object. This is not the default behavior. There must be some other lines of code before imshow() lines, which are modifying the figure window.

Hi, can you provide the code before imshow() to get a better idea of what's going on?
