评论： Richard Rees 2020-5-23

Afternoon everyone,

Attached are two figures, before and after the linking of axes of subplots. Annoyingly, the last row exponent is being switch off and the Y labels being reset to 0 when linking the final row together. I can manually reactivate it using the specify axis tick values and labels, but I need to remember what the exponent value was and input the Y labels again. I increased in the number y tick format to 4f prior to this because I think it is decimal point problem between the final subplot but the problem persists. Is there a way to stop this?

Thanks

Think would need to at least see the code to look at what you've done/are doing...

Which axes are being linked?

Hi, attached is the input file for the subplot code below (it's abit long winded). It all goes wrong at 'linkaxes(ha(16:18),'xy') %dP2' down the bottom. Prior to this everything works fine, I think it maybe because of the decimal place difference between the three subplots in that row.
