To display an average slope, you can use thederivativefunction in the channel drop down menu or thedifferentialfunction in thearithmeticmenu. In both cases though the window size is limited to 999 samples so if you are sampling at 1KHz, this would only give you a 1 sec moving window.
A workaround would be to use an Arithmetic expression like:
diff(resample(ch1,10),500)
毁掉的10倍,这将给一个5 second window if the original sample rate was 1kS/s. You will need to vary the decimation factor and sample size according to the sampling rate used on your data.
