You may now choose a couple of settings for your plot. Data styles refers to if the maximum or average values for each day are plotted.  e.g. If the max values are plotted for a hoist motor, then you will see the maximum temperature the motor reached for that day. If average is plotted, then the average.

Plot Span refers to the chart window.  In all cases, the entire Database time span is plotted. Everything may be acessed by moving the plot window back and forth.  However your data view will be determined by plot span setting.  Use 1 month for maximum resolution and 1 year for the best long term picture.

The plot options can be changed at any time, even when there is an active plot.  After you change the settings, just hit the plot button.

A long term trend is shown above using a 6 month window. The Title show the value you selected and the Maximum Value means that was the option selected.  It would save Average Values if that option was selected.

All Temperature values are in degrees Celcius, the scale is on the lefthand side of the chart. Note: that the scales changes with the data to give the best view, so please look at your scales.

The viewing window may be adjusted by grabbing and dragging the time scale on the bottom of the chart.

The chart may be printed, saved to a file, or put on the clipboard (for pasting to another program) by using the toolbar buttons directly above the chart.

You may change the values plotted by repeating the selection or options process at any time.
