Having equal axis scale for guiqwt's pcolor plot (like matlab's "axis equal" command)

[David]

Hello,

I have created a plot using guiqwt's pcolor command. The x and y axes
represent physical space, so I would like to ensure that they have the same
scale. I know that in matlab I can use the command "axis equal" to achieve
this - is there an equivalent option in guiqwt?

regards
David
