Channel value history screen
The dialog is used for graphical display of the history of channel values. The X axis of the graph represents the sampling time of
the value and the Y axis the value of the channel. The range of the Y axis is given by the channel 'offset' parameter (lower limit,
usually 0) and the ALARM4 value (upper limit). If channel data is not available for a certain time (a sensor failure or the control
panel was out of order), the graph is not plotted at that location.
