I've been playing around with this for a couple of days and have so far made a number of very useful charts.
One very cool one shows the current latency of our Citrix farm by office. The datasource updates every 15 minutes. I'd like to add the last updated time to the chart somehow, for example as a -titles_0_value or -caption. I tried making a variable and assigning it to the property, but that only gets the value when the chart is first opened. The last updated time is available in the db in a number of places... I just can't figure out how to display the data on the chart.
Does anyone have any insight on how to do this?
