While the basic widget you created is functional, you can make it do a little more. Click on the widget and wait for the pencil button to appear in the top right corner. Click it. This opens the Text Properties window again. This time, click on the button next to Thresholds. The Define Thresholds window will open.
What thresholds can do for your widget is change the text color and play a sound when the result reaches certain levels. This is perfect for giving a warning to everyone viewing the screen when their numbers get too high or low.
To the left of the arrow is a list of the calculations you specified earlier. The only one listed is Queued Calls, so make sure it's selected.
You can click above the arrow to set a new threshold. This creates a box above the arrow with a music note and a number in it. Click and drag the box to change the threshold number. Move it to the far right or left of the arrow to expand or condense the arrow's total range; by default, it represents a range of about 20. If you click the music note, you will be able to choose a system sound to play when that threshold is reached. Clicking on any section of the arrow itself will allow you to change the text color when the formula falls within that section.
Create a threshold at 5 and another threshold at 10. The fewer queued calls you have, the better, so change the lower end of the arrow to green. Click on the first section of the arrow, choose a green color, and press OK. Do the same for the middle and right sections of the arrow, choosing yellow and red, respectively. Click the music note above the second threshold and choose chord.wav.
When you're done, press OK, then Apply. Depending on your current number of queued calls, the black number should turn green, yellow, or red. Now, when your queue numbers change, the text color will change accordingly. If you accumulate 10 queued calls, the computer will also play a sound.
This is just one of the many widgets you can add to your Realtime canvases. Be sure to save your canvas often to avoid losing your work.
Adding Audio Alerts
When you add thresholds to a Realtime widget, you can also assign alert sounds. These sounds will play whenever the widget reaches a threshold. To assign a sound, click the music note above the threshold. This will open a file window, allowing you to choose a sound.
If you don't hear the threshold play, first make sure that the volume on the computer running the wallboard is turned up. You may also want to make sure your speakers are turned on. Test them by playing an audio file in any media player.
Supported file formats include .aiff, .au, and .wav. The sound engine used by Realtime Stats can support 8-bit or 16-bit audio data, in mono or stereo, with sample rates from 8KHz to 48KHz.
