Setting Histogram Zoom Factor

Set the Zoom Factor changes the number of data points that remain in the upper zoom window when pressing the zoom button. The range for the Zoom Factor is between 80 and 99, with a default of 80. Increasing the value for the Zoom Factor will narrow and widen the number of data points in the upper histogram more slowly. For the Zoom In function with the Zoom Factor set to 80, 80% of the previ- ous data will main in the view, with 10% of the data on each end eliminated from the view. When the Zoom Factor set to 98%, only 1% of the data on each end is eliminated from the view.

Zoom in and out using the Zoom In and Zoom Out buttons or the menu items from the Histogram menu.

Setting the Histogram Download Size

This control sets the number of 10MB sections that will be downloaded from the capture source each time a request is made for new capture data. The download size can be set between 1 and 50 10MB increments. The default is 6 or 60MB of data.

Set this value high if you need to load and view large sections of data at one time. A greater download size will increase the time it takes to perform each download. Surveyor also has a setting for local disk cache size which will also affect the performance of downloads.
