Hi
So does that mean that we cannot switch off the perspective when rotating? What I was hoping to achieve was to rotate the three-dimensional lattice of spheres without any perspective.

Hi Narcis If you just run the exe and hit the button you will see an array of red filled circles forming a lattice. However, you will also see that they still show perspective (i.e. the ones behind are displaced to give a sense of distance). You can rotate the lattice also by using the left mouse. T...

Spheres/Circles
I have tried that, and it is better but still does not eliminate perspective in OpenGL

3D drawing of circles/spheres
I have trying to draw a 3D lattice of spheres on a 3D Chart. If I use the circle point I do not get any depth (although I do if I use triangles etc). I read somewhere here that one can use OpenGL by using TeeOpenGL1.TeePanel := Chart1; //associate the component to your chart TeeOpenGL1.Active := Tru...

sensing series
Thanks. That does it. Very clever! I didnt know about an instruction like
SeriesIndex:=Chart[0].Clicked(X, i);
all the best

SeriesIndex:=Chart[0].Clicked(X, i);

Sensing series
Thanks, that partially solves my problem, which I realise I hadnt explained properly. A series consists of a list of X,Y values, numbered from 1 to a max number of items. So what I would like to so is to click anywhere on the chart, and then return the item value from one of the series, say Series1,...

Sensing series values
I have a chart on which there are say 8 series plotted, Series1, Series2,.....
Now I would like to mouseclick somewhere on the chart (not necessarily directly on a plotted series line), and automatically get the X value of say Series1.

Order of xvalues when datetime
I have a graph in which the XVALUES are datetime values. I add a button to add one hour to all values and replot. However, when values to the right of the graph go over 24 hours I get an error. How can I change the values displayed without resetting the order of plot. So for instance say the values ...
