I and my test user both thought that our browsers froze when we clicked on the Chart view selector the first time. However, I now realize that this happens because the default chart shows all the parameters for the location node. In my case, I have way too many parameters to show on one chart, so the chart isn't useful anyway. A couple potential recommendations:
- If the node has more than 5 or 10 parameters, perhaps the Location toolbar option should be disabled or a warning should be issued to the user before the system tries to create the chart.
- Perhaps the Parameters or Custom toolbar option should be selected by default instead of the Location toolbar option.
