Error: "Floating Point division by zero" when adding arrays with all zero values

[User (Legacy)]

The error occurs on

CfxFASDisArray : CfxDataArray;

ChartInst    : TChartFXCS;

ChartFXCS4.GetExternalData(CfxFundArray.InterfacePtr,0);

How can I check the max and min of the values if the values are not known to

the ChartFXCS4 until after the GetExternalData call which cause the error?

If I set the max scale to 100 before the GetExternalDate call does the call

then reset the max to the max in the arrays?

I entered this code but the error still occurs:

(the conditions for the if statements are never true)

if (ChartInst.Axis[AXIS_Y].Min = ChartInst.Axis[AXIS_Y].Max) then

        ChartInst.Axis[AXIS_Y].Max := 100;

if (ChartInst.Axis[AXIS_X].Min = ChartInst.Axis[AXIS_X].Max) then

        ChartInst.Axis[AXIS_X].Max := 10;

ChartInst.GetExternalData(CfxFASDisArray.InterfacePtr,0);

Thanks for you help,

You must have this code:

if (ChartInst.Axis[AXIS_Y].Min = ChartInst.Axis[AXIS_Y].Max) then

        ChartInst.Axis[AXIS_Y].Max := 100;

if (ChartInst.Axis[AXIS_X].Min = ChartInst.Axis[AXIS_X].Max) then

        ChartInst.Axis[AXIS_X].Max := 10;

AFTER you read the data, not before, the values of Min and Max are 

overridden by GetExternalData so these lines before GetExternal data have no 

effect whatsoever.
