Re: How to NAME a charttool?

I'm confused. The cursor tool is a regular component, just like the chart itself, a button or whatever. You can rename it to whatever you like: charttool.png This also enables you to use this reference in code (like "myFancyFadenkreuz.Active := checkItsRainingOutside();") without having to introduce...

Re: Line drawing

Isn't there a Chart tool for exactly that already built in?

Re: Polar Series

If you're using a PolarGridSeries, can't you just not fill the inner cells? That would certainly make some Kind of a "hole" in there. Also, placing something like a Bitmap in the centre of the polar diagram sounds appealing. Currently, I would not know how to best place some VCL component like a TPa...

Re: Could I have a hole in my polar series, please?

Good to know, I thought it was me not being able to use DrawZone(..) correctly.

DrawRing(..) however works like a charm.

Many thanks for your time so far!

Re: Could I have a hole in my polar series, please?

Thank you.

By the way, I stumbled upon the method TCustomPolarSeries.DrawZone(Const Min, Max: Double; Z: Integer).

Wouldn't that be able to achieve what I'm looking for?

Could I have a hole in my polar series, please?

I'm not sure if this is a feature request or if I'm just overlooking something. First, we had a pie series. Later came the donut series which is basically a pie series with a hole in the middle. Is something like this also possible for a TPolarSeries? A polar series looks like this: MainForm_2014-07...

Re: Error compiling with v2014

TeeChart default install path is %ProgramFiles(x86)%\Steema Software\[xxx]
As long as you don't dare to forcefully run your IDE with administrator privileges, you may not modify files placed in %ProgramFiles(x86)%.

If you installed TeeChart somewhere else then it might work.

Re: Error compiling with v2014

No. Your library path points to a folder of DCUs. DCUs (I guess they stand for D elphi C ompiled U nit?) were already compiled once when you ran TeeInstall.exe. If you want to make changes to the TeeChart sources I guess the "normal" way is to modify the sources and then run TeeInstall.exe again so ...

Re: Delphi XE6 Starter + TeeCharts Standard

Have fun! I'm also still rather new to Delphi (started in 2013). It has a few quirks but altogether, I'm rather happy with it.

Re: Error compiling with v2014

Your library path is most likely wrong. Just set it to where your TeCanvas.dcu is. I just installed TeeChart Pro (with Sources) to C:\Program Files (x86)\Steema Software\Source 2014.11.140512 XE5\ Therefore, my library path is C:\Program Files (x86)\Steema Software\Source 2014.11.140512 XE5\Sources\...

TPieSeries and TDonutSeries can't have no border

The pie and donut series both provide a "No border" template. However, when painting them with GDI+ and anti-alias (which is the default), they still have visible seams where they'd draw their border. Turning anti-alias off brings back memories from 1995 but removes the gaps. Please see the followin...

Re: Delphi XE6 Starter + TeeCharts Standard

I believe you did everything right. The reason you did not have those paths at all is that you probably installed TeeChart with another account you're running the IDE with? TeeChart setup adds the paths to HKEY_CURRENT_USER. If the administrator (or whatever) you used to install is not the same acco...

Re: TeeChart 2014.11 in a dll: Works in XE6, but not XE5

Sorry for further cluttering up the forum, but I can't find a way to edit my previous post. As it turned out, it got nothing to do with XE5 or XE6. The "older" XE5 installations still contained a "Library-Translations"-path for an older instance of TeeChart 2013.09. This way, one would see "2014.11"...

TeeChart 2014.11 in a dll: Works in XE6, but not XE5

Now here's a funny one: Thanks to the excellent article TeeChart and GDI+ inside a DLL we know that in previous versions, rendering a Chart with GDI+ in a dll required caution. The changelog for 2014.11.140512 also states: Protection against exceptions when using the GDI+ canvas from inside a dll. I...
