Hello,
I am noticing a mismatch between the real value of the scattering point in my plot and the y-axis. For example, my first scatter point's y-value is 2.7, but it is placed way higher than the 2.8 y-axis value in my plot. This is better illustrated in the attached image. Any possible solutions for this issue?
Thanks in advance! |

What version of Origin do you use? And could you share your project file? Thank you.

Hi, I am using the 2023 version. https://my.originlab.com/ftp/forum_and_kbase/Images/Critical%20Points_ForOrigin.opju
Please find attached the project file. The points marked as CP E0 seem to be at the correct position. The problem is found for the points of CP E1 and CP E2.
Many thanks. |

win -o Graph2 {doc -ef LP {lay -a;}}
I'm curious, what method have you used to plot the data? |

I used the 9 by 9 panel option, and then, through the layer management menu, I moved and connected the top and bottom plots.

Hi alliceinw0,
Aha, it is a kind of "magic" display...
The tick label now displays with 1 decimal digit only.
If you change it to show 2 decimals, you will see the "2.8" is in fact "2.75". |

minimax,
After re-scale ("lay -a") I haven't found any discrepancies between worksheet data and axis ticks - all points have been plotted correctly. Seems, that the problem may occur if adding a plot to a layer in a specific way without automatic re-scale - I have no idea, which one exactly. |

Hi aplotnikov,
Firstly, I do not see "lay -a" takes effect for Layer 8 (bottom-center) of user's project.
i.e. after it is run, the mismatching still appears in 2023/2024.
User's Layer 8 triggers the "discrepancy" since it sets the "Anchor Tick" option with 2.55 AND uses 0.1 as increment value.
Either removing 2.55 or changing 0.1 to be 0.15 can also workaround the display.
Indeed the current rescale logic is kind of magic (complicate).

Right, I considered layer 5 only, my fault.

Indeed it looks like a bug.  |

Thank you minimax, indeed changing the number of decimal points worked perfectly for me! |
