Select the Filter checkbox to display the Filter toolbar, which provides additional data filtering options. The x-axis: drop-down selector lets you change the display scale of the histogram's X axis between a uniform or logarithmic scale. Hover the cursor over a bar in the histogram to display the Filter and Zoom buttons.

Click the Filter button or click the bar to filter the table below the histogram by the data range corresponding to that bar. The selected bar turns yellow. Hover the cursor over the selected bar to display the Clear Filter and Zoom buttons. Click the Clear Filter button to remove the filter from the data range in the table below the histogram.

Double-click a bar or click the Zoom button to zoom in and display a new histogram that displays metrics constrained to the data range represented by the bar. The data range applied to the metrics data set displays above the histogram.

Click the plus or minus buttons in the filter conditions panel to add or remove filter conditions. Uncheck the Filter checkbox above the histogram to clear the entire filter.

Check the box next to a job in the table below the histogram to enable the View Job button. If the job is still running, checking this box also enables the Kill Job button. Clicking Kill Job will display a confirmation dialog to choose whether or not to terminate the job.

Click the View Job button or click the job name in the table below the histogram to open the Job tab for that job.
