TKnobGauge and other Gauges

[Eric]

Hi,

If I add a Chart with aTKnobGauge series on a form and want to use a TDBCrossTabDataSource then I get an accese violation. It seems it's not possible to use TDBCrossTabDataSource on gauges. But what kind of datasources are supported then? I can't anything of it in the helpfile neither on the forum.
And how else to add data to a gauge series?

Thanks,
Eric

Hi Eric,

I've tried it in the feature demo "All features\Welcome !\Database Charts\DB Crosstab source", changing the Bar series to a Knob series and it seems to work fine.
