The line chart that TGraph has already, is a series chart where the X-axis data is in increasing order starting from the smallest point. An example might be temperature vs month-of-the-year. Here is a sample line chart:

Alvaro, which type of chart are you looking for? What type of data are you working with?


I did the first one, the "Scatter Chart". It's is already working. I have to finish minor changes. I will send it to you when finished. In my modified class you can choose between drawing individual points or drawing a line between points, in this case in the same order that the points have in the array, although the distance between x values may not be constant and may increase and decrease.

I forgot in my previous posts to credit the author of the excellent class, Alfredo Arteaga.

Regards,

Alvaro

Hi Antonio, sorry I skipped your message yesterday. If the class is going to be included in the next release of FWH I will polish it a little and I will add some comments. Give me a few days.
