I implemented a cascade current mirror circuit as shown blow.
And I want to plot the output voltage Vout relative to the changes of input current (0<Iref<800uA) . I use DC-Analysis>Design-variable>start=0 / stop=800u then run the simulation
x-axis of chart in term of voltage and y-axis of chart in term of Iref
how can I change x-axis=Iref and y-axis=Vout
Like the figure below
