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
Not quite. As soon as you try to rotate using the left mouse button the perspective reappears.

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...

I have uploaded the actual program for you to see. I imagine I have done something stupid!!! This program is in an early stage of development.

Yes. But this still does not eliminate perspective.

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

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 ...
