The data filter helps to display only relevant information in the data window. It can also decrease the number of printed pages when the data samples are printed. The data filter allows you to:
· Hide sample points when the data did not change sufficiently.
· Show only data points that were sampled in a specified time period.
To apply the data filter, select the Data Filter… option from the View menu. The filter selection dialog box is shown below.
The filter can be disabled by checking the "No Data Filter" box.
Sample range filtering can be disabled by checking the "Don’t limit using xxxx" box for all the channels or for specific channels. Channels are selected by clicking on the channel pane.
Date range filtering can be disabled by checking the "Don’t Limit By Date" box.
The filter settings apply consecutively. It is therefore very easy to find settings that will display no samples at all. The LOGiTpc program will give you a warning if you selected a filter that results in no samples being displayed.
