5.6.3 Real-time Graph Menu Functions
The Real-time Graph menu functions are as follows (Fig. 5.19):
Figure 5.19: Real-time Graph menu
1 Sampling Frequency This pull down menu allows users to control the
desired sampling frequency (Hz). This variable can only be updated
when the real-time graph is not collecting data.
NOTE: Under some conditions, the sampled data will update slower than
the set sampling frequency, since sampling frequency is affected by the
number of parameters.
2 Time Scope This control selects the range shown on the x-axis and is
used to adjust the rate at which data is populated on the screen.
This variable can only be updated when the real-time graph is not
collecting data. The time scale is in seconds.
3 Copy Controls There are two distinct controls in this section.
Copy Data This function copies all the session data to the clipboard
in text format. Data is copied from the beginning of the session,
after the
Data Logging check box is checked.
Copy Picture This function saves the current graph on the screen
in bitmap (.bmp) format.
