Thanks Daniel for the minValue solution. It would not suit my situation
since the data which may give good visualization when minValue = 0 for some
data values would fail when I need to see how the flow is going for other
values. E.g.
[98, 99, 90, 94, 93, 92] Here I would like to have minimum set somewhere to
85. One may say to use chart_data.GetRange(1).min //* there is a function
which allows to get the minimum in the data, I forgot its syntax but looks
similar to what i have written.
* but I have a 2-D array of data. I plan to go with what asgallant
suggested.
