Scatter plot with 2 variables differentiated by color

[Benjamin Williams]

Is there a way to make the timestamp on the x-axis, the value on the y-axis, then the data points be the employee and differentiate different employees with different colors?

In short, I'm trying to see if different employees are consistent across time with their values. I'm not certain if workorder is superfluous data.

timestamp	workorder	value	employee
6/21/2016	111895-01655	15	5399
6/20/2016	111895-01654	19	5399
4/11/2016	111895-01653	4	567
8/18/2016	111895-01658	13	7082
8/14/2016	111895-01659	16	2867
6/27/2016	111895-01656	3	5399
3/26/2016	111895-01652	3	6846
3/21/2016	111895-01647	17	404
2/15/2016	111895-01643	46	1294
2/12/2016	111895-01646	6	4968
3/26/2016	111895-01649	5	6846

data points on a new line for each employee, as their own entry maybe?
