Re: TPolarSeries: Invisible Point at (0,0)

I hope I'm not getting on your nerves too much (it's Friday, after all), but I just had a quick look at the generated browser output: The buttons for quoting, editing and private messages are there. It's just that your styles.php outputs CSS information with empty urls and size of zero pixels: /* Se...

Custom Legend broken?

I didn't dare to enter this straight into the bug tracker, maybe I'm missing something. I believe the TCustomLegendTool is broken. Just create a new chart, add some series, and try to add a TCustomLegendTool . My observation is that it works flawlessly, except for the fact it is covered by a entirel...

Re: TPolarSeries: Invisible Point at (0,0)

This is more like a reminder to self about caveats when using a TSeriesBandTool on polar series : When using a TSeriesBandTool on two TPolarSeries objects, make sure both share the same value for the property RotationAngle. When calling Rotate(Integer) on a TPolarSeries, also call Rotate(Integer) f...

Re: TPolarSeries: Invisible Point at (0,0)

Holy cow, a triple-post. I found out that the anomaly shown in the last picture actually hails from a different "RotationAngle" of both series. If both series have the same rotation angle, then everything looks pretty good. I will try to provide a minimal example for tomorrow about what you can eas...

Re: TPolarSeries: Invisible Point at (0,0)

It gets even more interesting when we set "Close Circle" to False: Draw Style - Segments, Don't close circle.png What is that invisible point in the center used for? Can I somehow circumvent having lines to the centre? You might want to say " Sure, just don't use the Segments draw style ". The probl...

TPolarSeries: Invisible Point at (0,0)

I'm having trouble with the TPolarSeries. Consider this simple chart with two TPolarSeries: chart1.Axes.Left.SetMinMax(0.0, 20.0); chart1.Axes.Bottom.SetMinMax(0.0, 20.0); Series1.AddPolar(0.0, 10.0); Series1.AddPolar(90.0, 10.0); Series1.AddPolar(180.0, 10.0); Series1.AddPolar(270.0, 10.0); Please ...

Generally disable the new "hover" effect of 2014.12

Hi there. The new 2014.12 release of TeeChart comes with a new "hover" effect (see: New and Improved Features ). As cool as it is, it is a too drastic change in behaviour (and performance, for some type of charts). While I'll happily be using it for new stuff, I'd like to turn it off for existing pr...

Re: XE7: "DclTeePro921.bpl cannot be loaded" but yet it can

Thank you. For now, it looks like it was a false alarm and not related to TeeChart anyway. I installed the IDE Fix Pack for XE7 and disabled the package cache. Now an entirely different package resulted in the very same error, but TeeChart not anymore. I rebuilt that very package and it looks like I...

XE7: "DclTeePro921.bpl cannot be loaded" but yet it can

I'm puzzled. I installed the new 2014.12 release for XE7. Just the binary, no sources. It works like a charm. However, when starting up RAD Studio, it states that Package C:\Program Files (x86)\Steema Software\TeeChart 2014 for RAD XE7\Delphi21.win32\Bin\DclTeePro921.bpl could not be loaded. Access ...

Re: Fade out transparent image on top of a chart

That is bloody beautiful! :D It never entered my mind the TRectangleTool can be textured. This is exactly what I want. And it looks really good. By the way: I couldn't get the TeePNGImage-include to work. I found no binary dcu and hat to include some source file. After that, it didn't even work. St...

Fade out transparent image on top of a chart

TeeChart has a lot of funky stuff. I can place some good-looking text anywhere on my chart using the TAnnotationTool. Have a look: chartTextAnnotation.png Now the time has come to place an image on top of the chart. Not even that, I need to show it, and then slowly fade it out. How would one go abou...

TChart.SeriesList.Add(..) vs. TChart.AddSeries(..)

I have a feeling that something this obvious is somewhere in the documentation but I can't find anything. How would one go about adding a TChartSeries at runtime? Please have a look at this: implementation uses VclTee.Series; {$R *.dfm} procedure TForm3.Button1Click(Sender: TObject); var newSeries: ...

How to determine if all axis labels are visible?

Imagine a series (Bar Series) with every item having a label. We can set something like "labels -> min separation" of an axis. That's pretty cool. Instead of overlapping Labels, some are getting hidden. 1.png 2.png My question is: How can I find out whether all labels are still visible or if some go...
