Exponential chart

Post by nadou31 » Thu Jul 10, 2014 10:35 am

Hello everyone!
*Please don't mind my english, i'm french (and desperate... :cry: )*
So, i'm new to java and i would like to create an exponential chart and also extract the function's parameters (slope and intercept) chart but i don't know how to start...
The jfreechart's documentation is kind of lacking on that part.

Can you help me please? :roll:

You mean a chart like this:

Then just plot the values of an exponential function.

Slope and intercept are mathematical properties of (linear) functions, check here https://www.google.com/search?q=slope+i ... gws_rd=ssl

I do not think that JFreeChart will help you calculating those parameters, it is basic math.

Hi,

Thank you for the answer.
Yes, this is exactly the chart that I research to produce.
It's possible for an logarithmic chart however I didn't found out for an exponential one...
Anyway, thanks again for the quick answer. :-)

Regards,
Nadia.
