## Logarithmic mode for plot...

Maple 2015

The scale of vertical axis is logarithmic and function in each interval must be linear. When I use the command " mode=log " the shape of lines are deformed into curves, however when I use the command " curve ", the shape of lines remains straight. I can use right-click for changing mode to logarithmic scale but is it possible to use label font for vertical axis as well as size, resolution and other options in the command "curve" ?

Thanks alot

## Increasing CPU usage...

Maple

Hi

When I run a maple file it uses 25% of CPU.

When I run 2 files, the half of CPU is used.

How can I change the preferences for using most of CPU
