Thank you for your reply. But is there any chance to get a method which calculates the correct 3d coordinates from mousex and mousey and a given z-value? Imagine a 3d chart which is rotated several degrees. Now I would like to start drawing a rectangle at z-position 0 where the user pressed the mous...

Determining chart values from 3D position

Hello, could you please help me with the following problems? We are using custom x- and y-axes, all default axes are turned off and chart.view3d is set to true.

Chart double click

Hello,

I just found out that the onclick-event is fired before the ondblclick-event. Is there any possibility to get the ondblclick fired before onclick? This imho the normal behavior of all controls of Delphi.

Best regards

WM_CONTEXTMENU message when clicking with right mouse button

Hello, I am not sure about this but it might be that we have noticed that a WM_CONTEXTMESSAGE is sent when you click with the right mouse button in the TChart. If there is no context menu on the parent of the TChart then this message is sent to all controls and the application is blocked in the mean...

PeriodAlign

Hello, we are using TeeChart 7.04 and I think I have found a bug concerning the PeriodAlign property. It seems that setting this property does not have any effect when using curve fitting, moving average and exponential moving average. The series always looks the same. Could you please help me with ...

Legend title exceeds legend box

Hi,

we encountered the following problem with Teechart 7.03:

The size of the chart legend box is set via the length of a series title and not via the legend title itself. Is it a known issue and how can we work around it?

Best regards

Hi! I am experiencing difficulties with these series. Add one fastline series to the chart and set the penstyle property to something different to pssolid and set the pen width to 2 for example. Then zoom in several times and the computer will hang. Also I would like to ask when the new maintenance ...

Hi Pep!

Yes, I made it just like in the example. I am currently using Teechart 7.01. Is this a bug in this version or is it because I use automatic axes?

Regards

The first one should start at 0% and end at 33%, the second at 33% and 66% and the last one should start at 66% and end at 100%. However, I have set the positions using istartpos and iendpos but nothing happens. All...

Hi,

I am using solid colored lines but if the color is different to black, you can recognize a loss of performance.

I am using lineseries because I want to enable the pointer property when less than 100 values are drawn.

Best regards

Performance issue

Hi!

I noticed heavy loss of performance when the colour of a line series is different to black. The whole chart seems to be painted much more slowly.

Is this a known bug? This happens with Teechart7
