Set axis format in VC++ MFC

[User (Legacy)]

Dear Support People,

I want to set the x-axis format to "AF_SCIENTIFIC" in my VC++/MFC project

with #import drective.

The code i wrote is:

m_pChartFX->Axis->Item[AXIS_X]->Format = AF_SCIENTIFIC;

But i got a compile error:

error C2664: 'PutFormat': cannot conver parameter 1 from 'enum CfxFormat' to

'const class _variant_t &'

What should i do? What is correct syntax for setting the format?

Thanks!

The Axis.Format property is declared as a variant so that you can pass both 

predefined formats and custom strings. To use AF_SCIENTIFIC (or any of the 

prededfined formats) your code should look like

VARIANT v;

V_VT(&v) = VT_I4;

V_I4(&v) = AF_SCIENTIFIC;

m_pChartFX->Axis->Item[AXIS_X]->Format = v;

Note that you could also use one of the MFC/ATL wrappers around variant but 

in the case of an integer there is nothing to cleanup.
