Add the new series by right-clicking on the graph and selecting souce data.
Then select this new series in the graph and click on format series again by
right-clicking. Select patterns and select the 'automatic' for the line
(which will be 'none').

I have got a chart of stock as Open, High, Low , Close. Now I want to add
a
line like a trendline to the chart where the data is calculated in a
separate
column at the side of the previous data.
Is it possible to do this in Excel?
The trendline that I want to add is not possible to draw with the features
already available in Excel 2003.
