Hi All, I want to plot the slope of a waveform. Is there any way in xschem to do so. Actually I am designing a PTAT current source and I need the exact slope of gm for temperature compensation.

If the temperature is the X axis the slope of a waveform

xxx

can be calculated by this expression (including double quotes):

"dxxx/dT; xxx deriv()"

the expression before the

;

is a name to display for the waveform. You can use any text you like.

Thank you @Stefan Schippers. 🙂
