Hi,
Please how can I use origin to construct a phase diagram such as the one I have attached to this message.

Looking forward to your quick response.
Thank you in anticipation.
Isaiah

Hi,

Could you please tell me what your data looks like in details? For example, is the data of phase boundary lines already known?

Thanks,
Amanda

Hi,

How to construct the boundary lines from your data? Do you want to perform a linear fit on the data or do you have formula to calculate boundary from the data?

Thanks,
Amanda

Hi,

If you don’t know the formula, Origin cannot calculate the boundary.

Thanks,
Amanda
