Model-driven apps allow you to create multiple charts per table, ordinarily, the first chart is the default chart when opening the charts pane. Setting a system-wide default chart takes a bit more work.
Figure: The first chart in the list is the default
In the example above “Leads by Rating" is the be the default system-level chart of the Lead table. Some additional work is required to change the default. The easiest way of doing this is with XRMToolBox and the Advanced Chart Editor plugin.





Note: If the chart that was modified to be the new default is not at the top of the list, check the first chart in the list by exporting it and confirming the isdefault element is set to false.
Where there are two charts with the isdefault element set to true, these default charts will be at the top of the list and sorted alphabetically.
For example, if “Lead by Rating" and “Lead by Source" are both set as default then they would both be at the top and sorted alphabetically. The remaining charts would then be sorted alphabetically.
This can be desirable in some instances.
Figure: Two sorts, first alphabetical sort for the defaults, second alphabetical sort for the remaining charts
