Two Scatter Drawn In One Chart

[Anonymous]

Hi,

I  have the ffg:

------------------

Period 1(DATE)

StrikePrice

Volatility

----------------

------------------

Period 2 (DATE)

StrikePrice

Volatility

----------------

I can make a Scatter chart of StrikePrice vs Volatility, for 1 Period.

And another Scatter Chart for Period 2.

But I need to make 1 Scatter Chart with both periods.

Where you can see different periods based on their symbols

for eg. x- period1 and 0-Period2.

Please see Attachment for Sample.

Kind Regards

Razak
