Why incorrect values are displayed in Dial Charts configured as portlets in the Dashboard?
This problem occurs when the values of grid or graph configured in dashboard are cached. This results in old values getting displayed in the dashboard. This is due to the dashboard cache property enabled for dashboards. You have to refresh the dashboard portlet to solve this issue. To avoid refreshing the portlet every time, you can disable the dashboard cached property. For faster display of dashboards, the dashboard cache will be enabled by default. However it can be changed, as it is a configurable property available in 'arc.properties' file. This applies for ARC5.8 and above versions
