Charts and Data Labels

there are two charts i have posted here.

1. the torque time diagram, the chart should have the accel & decel torque series and the net torque + friction as the same series. Is there a way to plot them as a single chart or to just change the colour of the lines to match each other??

2. the cycle time and RPM diagram, I would like the data labels to display the units next to the value (i have typed the units in the data label). but if i change the value the data label doesnt chage value anymore. is there a way to make this value update and keep the units??

1. Create a single set of data with empty cells between each group of data so the line is not drawn between the last point of 1 group and the begining of the next.

2. Use custom number formats. Either on the cells, in which case the axes will also display the unit text. Or just on the data labels.
