Hi Pep,

Thanks for your suggestion. I'll give it a go.

Hi Narcís, The IStartPos and IEndPos were exactly the properties I was after. Thanks for your advice! Regarding your first response, I have realized that I was asking a wrong question. I actually wanted to know if the point under the mouse cursor lies in a band/rectange whose boundary is determined ...

Hi, I've got a chart that has a bottom (time) axis and a couple of vertical custom axes. I need your help to be able to achieve the following: 1) Given the mouse cursor position, determine which vertical axis the mouse is over at the moment so that I can calculate the corresponding coordinates. Norm...

Ok, then guess what - you have just given me a reason to update my development environment today.

Hi Narcís,

Thanks for the suggestion! Do you know if this is supported by TeeChart v7? I'm registered user of version 8 as well but I do not have it installed at the moment (so many things to do before I'll be able to migrate to RAD Studio 2007 and TeeChart v8 ).

Hi, I have to visualize a dependence of several kinds of data on time. For example, A=A(time), B=B(time), C=C(time) and so on. Bottom axis shows the time and the left axis shows the data series, be it A, B, C etc. I have a legend with check boxes that user can use to toggle the visibility of the ser...

Hi Yeray, If I understood well, you're trying to achieve something similar to the following. Note that we compare the maximum and minimum of the bottom axis and, if they are the same, we're showing only a day and we have to show only the 5 last characters of the Labels: Thanks, although this is not ...

Hi Yeray, Why don't you try to compare partial strings (at labels) to identify the same day points? That might be possible (using TChartAxis.LabelValue method), but even then, how can I possibly know upfront at which data points the labels will appear? Note that we are still within the OnGetAxisLabe...

Just talking to myself. One idea would be to determine the actual value of axis increment (not the desired value as held by the Increment property). Should this value be less than one, I would consider that as an indication that there are at least two or more labels for the same day. I discovered th...

Hi Narcís, Maybe you could use the OnGetAxisLabel event for that. Thanks for your suggestion. This does tell me where I'm supposed to insert my code, but it does not tell me how do I determine if there are more than one label for the same day in month, at that time. Do you have any idea? Thanks, aga...

Hi all, Background: Bottom axis displays values as a datetime (series' datetime property is set to true for that axis), Increment property equals to one hour and ExactDateTime is set to False because I didn't like that alternating label "effect" when panning the chart with mouse. My problem is that ...

Maybe a bit late, but let me thank to both of you for providing suggestions that led me on the right track!

Hi, I have a TChart that is used to display trend history of various data. Bottom axis is a time axis, data are divided into multiple series. Now I also need to visualize certain events that occured during the history. So, I need to be able to draw a vertical line at certain date/time across the who...

Hi, I've been trying to install Teechart Pro VCL 7.11 into both BDS2006/Win32 and Delphi 2007 for Win32 at the same time (binary installer first, then source code and finally launched TeeRecompile.exe). Everything went OK. Then I tried to compile a new features demo example, while I was successfull ...

Thanks for confirmation. It's nice to hear that this bug has already been solved in the forthcoming v8. Can't wait to get my hands on it.
