Hi
i've created a custom symbol based on the amchart-trend symbol from the Osisoft GitHub repository.
I just made some changes to allow it to display stacked area charts.
Then, i added some code to allow users to change display start time and end time by zooming in the chart.
I did that using two listenner from the amchart library and the 'TimeProvider' parameter. See the code below :
That works great.
Well it seems... the problem is :
When a zoom is made in the graph, display start and end time are actually updated, but then if i use a link (wich is on the same display) to go to another one, i get the following error :
The navigation link is setted to "set start and end time"
I don't understand why i get this message...
Any ideas how to fix that ?
Thanks
Hello Wende,
If I understood correctly, you are getting startDate and endDate properties of the chart.lastZoomed object from AmCharts and you are using then in the requestNewTime method, which is a method from PI Vision.
I see that the error comes from PI Vision (editor file) which expects the start property to have a replace() method which doesn't exist. Therefore, my guess is that the startDate from the amChart is not compatible with the input of the requestNewTime(). You will probably have to "transform" the object to something more suitable. This is how I would start troubleshooting this problem.
It is difficult to help you since I don't have the source code of this project.
