Thanks for developing a great product like GChart which integrates so
easily with GWT and works like charm. I had a query - I want to draw a
chart where I can click on any point along the x-y axis to determine
the point cordinates in model units. Once I get that, I can do an
addPoint() to add the point to the curve.
I tried doing that in GChart but I did not find any methods through
which I can handle a mouse click event to get the x-y cordinates in
model units. I can get the cordinates by implementing an EventListener
for the chart but those cordinates are of the browser window and in
different units. So it does not help. How can we accomplish this in
GChart?
Also, as GChart is a subclass of widget, I can use widget's methods on
it. But as Curve, Point are classes enclosed within GChart, I cannot
use widget methods on it. Am I right in saying this?
