HTML 5 Line Chart Jaspersoft Studio Prof

[patrick_vonbruel]

Hallo,

i can't find a tutorial, how to create a HTML 5 line chart.

The issue i have:

I want to create a line diagram, which shows me all the values over the timestamp.

I have arround 6000 values with timestamps. And i want to have each of those values in the diagram.

When i try to create a HTML 5 diagram, i get the message:
