You can switch the x and y axis for the charts for the Monitor Statistics in the Performance Monitor.
In the Performance Monitor. you can click a data point in a higher-level chart to drill down to a chart for that specific statistic.
When the Performance Monitor is capturing statistics, the display is updated every time the statistics are gathered. This means that you could be reviewing some statistics and they would change while you are viewing them. The Lock Chart function freezes the display with the current time slice but the Performance Monitor still captures the new information from the database.
