Hello,
This is a new subject. However, I don't know how to make a new post because I didn't find any button other than "postreply".
I want to add a histogram to an existing curve on a chart. The aim is to give a statistic of the data contained in the curve. So, I intend to use a THorizLineSeries to represent the histogram which will show confident range among the values of the curves.
The problem is I didn't find any example to do it.
Could you show me how to add the histogram, connect it to the existing series, set the function to "histogram", set the number of bins (as referred to the Matlab function hist(x,n) where x is the data and n is the number of bins (classes of data)) ?
Please give the example in Delphi.
Thank you in advance

I'd suggest you to read the "Tutorial 7 - Working with Functions", shipped with the binary installation, to understand how the functions work in TeeChart.

Then, you'll find example about the Histogram function at "All features\Welcome !\Functions\Statistical\Histogram" in the Features Demo program also shipped with the binary installation. Look at the "Source Code" and "Form" tabs at the bottom to find all the code (Delphi).
