Bug 428880

SUMMARY
When you have an system monitor widget on your desktop to monitor memory, and want to manually set the Y range.
The input box only accepts values upto 99.999 which is in KB, ~97,6552734375 MiB.
This ofcourse is nowhere near usable as most systems have memory in the ranges of GiB.

The automatic Y-Range is also flawed because it makes the chart too short because it uses a max value that is like 2x the available memory.

STEPS TO REPRODUCE
1. Add the system monitor gaget on the desktop.
2. In the "Appearance" section:
   Select "Line Chart" as display style.
3. Click "Apply"
4. In the "Sensor Details" section:
   Add fe. "Used Memory", "Dirty Memory" and "Used Swap Memory".
5. Click "Apply"
6. In the "Line Chart Details" section:
   Uncheck "Automatic Y Data Range"
7. Try to input a value higher as 99.999 (Not possible)

OBSERVED RESULT
The input box only accepts values upto 99.999 which is in KB, ~97,6552734375 MiB.
This ofcourse is nowhere near usable as most systems have memory in the ranges of GiB.


EXPECTED RESULT
That you can input values that are usable for your memory size, so you can have a graph that is visually usable.
