You can elect to use a chart adjustment factor to allow multiple sources to be displayed on the same chart with finer-grained control over how the data are displayed. For example, the following chart displays four binary data elements. Each has values of 0 or 1 so the chart wouldn't be useful because all four lines would be plotted on top of each other. By applying an adjustment factor to one or more of the lines, we can shift where they appear on the chart. Note that for visual appeal, we have raised the first device off the X axis by adding to its value (+1). In this instance, the effect was achieved by applying a simple linear transformation to the data to be charted:
| Item | Setting |
|---|---|
| Line 1 | + 1 (plots on 1 and 2) |
| Line 2 | + 3 (plots on 3 and 4) |
| Line 3 | + 5 (plots on 5 and 6) |
| Line 4 | + 7 (plots on 7 and 8) |
| Tick Labels | off,on,off,on,off,on,off,on |
| Tick Locations | 1,2,3,4,5,6,7,8 |
| Y Axis Range | 0-9 |
These transformations are applied in real time and do not change the underlying data
You can elect to use custom labels on the Y axis of select chart types. This gives you greater control over how your axis will appear. For example, consider the following wind direction chart:
Note the labels on the Y axis connoting direction. In this case, the data being plotted are compass directions in degrees (0-360).
To change the Y axis labels, go into the device settings and tick the Y axis controls group if it's not already displayed.
In this instance, we want five marks on the Y axis to represent compass degree direction values of 0, 90, 180, 270, and 360. Add corresponding custom labels int the 'Tick Labels' field. Note that the number of tick labels and the number of tick locations must be equal in order for them to display properly. It's also best for the tick location data to be within the expected range of the data to be charted.
| Label | Location |
|---|---|
| N | 360 |
| W | 270 |
| S | 180 |
| E | 90 |
| N | 0 |
You can also use this feature to force your charts to display Y axis values in a preferred way. For example, for a relative humidity chart, you might set the Y axis min/max to be 0 - 100 but you also might only want four Y axis labels:
| Label | Location |
|---|---|
| 25 | 25 |
| 50 | 50 |
| 75 | 75 |
| 100 | 100 |
Or only three labels:
| Label | Location |
|---|---|
| 25 | 25 |
| 50 | 50 |
| 75 | 75 |
or add units:
| Label | Location |
|---|---|
| 25% | 25 |
| 50% | 50 |
| 75% | 75 |
| 100% | 100 |
