The Graph Report gives a dynamic, graphic view of the logged data from the weather station.
Each Channel can be selected and/or de selected by clicking in the Channel Name in the graph legend to the right of the graph.
As the mouse pointer moves over the graph, the values for the relevant channels are shown on the legend to the right of the graph and the current Date Time is shown in a panel under the Date Time axis
You can zoom in on any section of the graph using the mouse click and drag technique. A Zoom All button is provided to return graph view to the full set of data. A Zoom Previous button is provided to restore the graph to the last zoom setting.The scroll bar under the graph gives a visual indication of what proportion of the data is being viewed during a zoom. It can also be used, with mouse click and drag technique, to pan the the graph view to the left or right of the current view
The graph can be viewed in Standardize or Normalize Mode. When first displayed the graph is in Standardize mode. In Standardize mode, values are plotted on the graph in their given units. (ie 10 degC will be plotted as 10, 1023milliBars will be plotted as 1023)
Sometimes, when comparing values of vastly different magnitude, the Standardize Mode of graphing is of little use. For example, if you are looking at the increase in a few millibars of barometric pressure relative to an increase of 5degC in air temperature you will not see these changes on a Standardize mode graph with axis of 1030
To overcome this the Weather-Pro graph can be displayed in Normalize mode. In this mode, all values are displayed as a percentage of the maximum reading for that channel so the few millibars of barometric pressure will be displayed across the full height of the graph as will the increase of 5degC in air temperature. This allows the changes in to dissimilar values to be compared on the one graph.
The Graph Report can be printed at any time either by using
