The charts’ scales will automatically adjust for the data captured. To zoom in on a portion of a chart, click in the chart
and drag a box over the portion to be enlarged. Scroll bars are displayed in the magnified chart. See Figure 12.
It is recommended to stop conversions before clicking on charts. Transactions are stopped when selecting a chart,
and samples may be missed.
3.3.3.1 Max Samples Field
The charts will display a maximum number of samples based on the value entered in the Max Samples field. It is
recommended to stop conversions before entering new values into the Max Samples field. Changes take effect
immediately.
The Max Samples field should not be made too large. Otherwise, the window will update slowly and samples will be
missed. When using the default sample count, generally the Maximum Samples field should be less than 500
samples and may vary depending on the PC hardware. To view a larger number of samples without missing
samples, click the Quick Measurements tab to bring it forward, wait for data to be collected, stop conversions, and
then click on the Graphics tab to bring it forward.
