• Sensor Reading list – list of sensors and their individual readings
• Time bar – provides an easy way to specify date ranges in the main graph
• Main graph – displays the selected sensor readings in the specified date range.
Graphing Sensor Data
• Click the ‘Graph’ button at the top of the screen.
• Select one or more sensor readings – Each DataSnap is displayed in a tree at the left of the screen. Clicking a DataSnap
reveals its list of sensors. Clicking a sensor reveals its available readings. Click the checkbox to the left of each desired
reading to display its data on the graph. A maximum of 14 readings can be shown on the graph. To widen the sensor list,
hover the cursor over the vertical border between the sensor list and the main graph. The cursor will change to a horizontal
arrow. Click the left mouse and while holding down the left mouse button, drag to the right.
• Specify the date range - The time bar at the top of the screen shows a range of selectable dates. See figure 18.
Figure 18 – Date/Time Selection
The time bar allows for quick and easy filtering of data by date. The selectable areas in the
time bar expand and contract based on the screen size but can be adjust manually as well.
Within the time bar is a range selection window that defines the date range that is displayed
in the main graph area. This is shown in figure 19.
The date range can be adjusted by dragging the gray rectangles on the right and left boundaries of the range selection
window. Dragging the left most range indicator to the left will change the displayed start date in the main graph to an
earlier date. Dragging it to the right will change the displayed start date in the main graph to a later date. The right most
range indicator behaves similarly and effects the end date on the main graph. The selected date range is displayed
immediately below the range selection window.
To maintain the same number of days in the date range but to see a different range, simply click anywhere in the selection
window and drag it to the right or left.
To select a single day, click on the date in the blue region at the top of the time bar
. As an example, figure
23 shows that Thursday January 19, 2012 has been selected. To select multiple full days, left click on a date and while
holding down the left mouse button, drag to another date and release the button. The
selection range will be highlighted in yellow as the mouse is dragged. The selection window
will now change to the range that was selected. As an example, Figure 20 shows how the
time bar would look while clicking ‘Wed, 18’ and dragging to ‘Fri, 20’. Once the mouse is
released, the range selection window will move and the main graph will display data for the
three selected days.
If the sensor’s data spans a wide range of dates, it may be difficult to set the dates of the range selection window. To
modify the size of each time unit in the time bar, click and drag either end of the yellow scrollbar at the bottom of the time
bar. The time units will change according to the size of the scrollbar. Figures 21 and 22 show two possible scenarios.

To view a different date range in the time bar, click the ‘Graph’ menu at the top of the screen.
• Main Graph - Each selected sensor reading will be displayed as a separate series in a unique color on the graph. If no data is
displayed on the graph, it is likely because the date range specified in the time bar, falls outside the actual reading dates. To
see details for specific readings, move the mouse around the graph. A gray vertical line will span all the visible series and a
