Customizing Graph Display

Performance Explorer displays graphs in a standard format but offers numerous possibilities for customization. You can change colors, line width, and line styles. You can change scaling options, insert markers, and more. These display options can be found on the Series tab, which is a contextual tab. It displays when you create or select a chart.

  1. Create a chart, drag measures from the tree onto the chart, and select a graph or a measure from the measure list.
  2. On the Series tab, in the Line Style group, you have the following options:
    • Style: Select from various line styles.
    • Color: Select a color.
    • Width: Select a width.
  3. In the Series group, you have the following options:
    • Scaling: The scaling factor allows you to visually equalize graphs in a chart. This means that measures with big values and measures with small values can be displayed appropriately and a meaningful chart can be drawn. Without scaling, measures with small values would display as flat lines, while measures with big values would display as steep lines. To enable auto scaling for all graphs in the chart, click Scaling in the Chart group on the Chart tab.
    • Display as: Select a display type for the selected graph. This can be Line, Candle, Candle with sticks, and Area.
    • Source Type: Select one of the following source types: Average, Count, Sum, Maximum, Minimum, StdDev.
  4. In the Display group, you have the following options:
    • Markers: Markers show the measured values in the chart.
    • Null Values: Displays the null values for the selected graph.
    • Measure Bounds: Displays the bounds for the selected graph. You can configure these bounds in the Automatic Threshold Generation dialog before you start a load test.
    • Performance Level Conditions: Displays the performance levels for the selected graph. You can define and assign performance levels on the Reports tab.
    • Normalized Values: Displays normalized values for the selected graph. Normalized values are values per second.
    • Standard Deviation Area: Displays the standard deviation for the selected graph.
    • Visible: Click this check box to show or hide the selected graph. You can also use the check boxes in the measure list to show or hide graphs.
