Have you actually been able to read /etc/passwd this way? I tested this on a few of our servers and it does not work. As far as I know, there is access
to files in resources, custom pages etc.

Deferred transitions were only implemented with a single instance of a program deferring the
transition. To have several instances, MIDAS probably needs to be extended. Certainly this
was never tested, so it's not a surprise that we get a segmentation fault.

Looks like a localisation issue. Your floats are formatted as "6,6584e+01", whereas the JSON decoder expects "6.6584e+01".

This should be fixed in the latest commit to the midas develop branch. The JSON specification requires a dot for the decimal separator, so we must ignore |

The histories capture key events from 'r' 'u' 'y' and 'Escape' for various functions like rescaling etc. However, this also means that if we include an

I agree with you, option 2 is better and works well.
The only problem is that if you are showing multiple histograms in the same window the keyDown even will affect all of the histories in the window.
This may be the intended behaviour, but I think that if we can find a way to have the event affecting only the intended history (focused element for example) |
