Log Analysis

Time Difference

calculates the time difference between log entries, useful for check for intermittent sensors.

Value Difference

the difference in values between each log entry

Rate of Change

This is not a very good graph, it needs reworking but it can be useful in select situations.

It attempts to detect the positive and negative movements in the value and mark the change of the value per hour, the value change per period of change, and the duration of the period of change.

Changed the log_window_size option will help tune results depending on the log size and granularity required.

Graphical

picture bar

A bar graph using pictures, this takes an image (pic_to_use=flower.png) and divides it into three sections repeating or stretching the middle section to fill the bar. These are set with top_cut_location and bottom_cut_location which are the amount of pixels down from the top.

use_val_set= day average 
             day min
             day max 
             day range
             last

middle_method = repeat
                stretch  

Animation

Icon

Draws a bar on a supplied image, when animated can be overlaid onto a video to provide a graphical display.

Set an image with an area to be replaced by the value display bar
