widget_bar - add support for independent min and max values for each expression

[lucasbender@…]

As the Bar Widget support two expressions (expression and expression2), why not separate min and max values for each two expressions.

A simple example of use of this feature is for tracking asymmetrical interfaces (network devices) like over a ADSL connection (for example); like in my case the downstream bandwidth is over double than my upstream, and the upstream bar get automatically unscaled because lack of this feature.

Thanks,

The reason for not having different min/max values is autoscaling: the whole bar autoscales, that means there is no separate min and max are calculated for lower und upper half.

If you want to scale them independant, you can always add a constant factor to one of the expressions, for example

expression  netdev('eth0', 'Rx_bytes', 500)
expression2 10*netdev('eth1', 'Tx_bytes', 500)
