For TAChart: how to set right-axis units as function of left-axis units? lazarus / 55-TAChart ---------------------------------------------------------------------- dkjMusic · 2011-10-28 10:48 I like the "auto-scaling" of the left axis in my plots - no muss, no fuss. Now I want to, for example, also have the same tick mark positions on a right axis but with the tick values in different units (degrees C vs. degrees K, g/mL vs. mol/m3). Is there a simple way? ---------------------------------------------------------------------- Ask · 2011-10-28 11:31 See axistransf demo, "Linear" page -- it contains almost exactly the case you requested (degrees C vs F). ---------------------------------------------------------------------- dkjMusic · 2011-10-29 11:11 Thanks, Ask. Will do.
