history plot editor resets "zero ylow" to "n"

[dd1]

the history plot editor is resetting ODB “Zero ylow” to “n” and the checkbox for setting this value has disappeared. now I have to manually edit 8*4 (or more) history plots so they plot correctly again. “zero ylow” is used by the old history plot generator and we should restore the checkbox and change the editor to leave the old value unchanged. K.O.

[dd1]

for compatibility between old history plot generator and new plots, “zero ylow” set to “y” should mean the same as min=0, max=+inf. (unless min and max have other values? need to check the old history plot generator).

since the old plot generator is the only way to make long-time-scale plots, we have to keep it around and both plot generators should be compatible in their configuration.

K.O.

I removed the “zero ylow” in favour of the min, max values which are more flexible (like you can fix the upper scale and keep the lower one auto-scaling). Rather than putting this back, I would recommend to change existing plots to use the min/max values. If it’s too much manual work (8*4 plots can be done in five minutes), one can invent some code which transfers an existing “zero ylow” automatically into a “min=0, max=+inf”.

list of history plots in the alpha-g test system. I hope we are not demanding that all experiments have to manually update all their history plots just because we wish to remove “zero ylow”. I can give you a list of history plots from the alpha-2 experiment, it is much longer. And BTW, as we update midas in the alpha-2 system it will be me who will have to do all the converting, so I have a direct interest in keeping things compatible. K.O.

I’m happy to change all your history plots. Shall I do it?

[Stefan Ritt]

Actually what we can do is to add code directly on the history page looking for the “Zero ylow” flag. If it’s there and true, the code can modify the ODB with correct min/max values. This is just a few lines of code, which will fix all existing plots, without having to bring back this check box again.

[Stefan Ritt]

Actually looking at the code im mhistory.js:463, I see

‌

   if (this.odb["Zero ylow"]) {
      this.autoscaleMin = false;
      this.odb["Minimum"] = 0;
   }

So if “Zero ylow” is in the ODB, it is obeyed. If you do have an old plot which is not showing correctly, send me the URL and I will check.
