Re: Colouring points individually

Yeray, I think that both properties 'ColorEachPoint' and 'ColorEachLine' are true by default, and so are not saved to stream with the method SaveChartToStream. So when I then use the method AssignFormat to apply a 'template' from a saved graph to a new series, these two property settings will be abs...

TLineSeries segment colours

Hi, With a TLineSeries, I colour values according to a quality attribute, using TLineSeries.AddXY(Const AXValue, AYValue: TChartValue; Const ALabel: String; AColor: TColor), and everything is fine. Each line segment takes the colour of the following point. Ideally, I'd be able to colour the line seg...

Re: Creating a custom legend

Hi Yeray,

Thanks for the suggestion. This would work well if we could prevent the dummy series from appearing in the list of series shown by TChartEditor. Is this possible?

Re: Creating a custom legend

Hi, I want to do something similar, except that: - I'm using a TLineSeries, so I need to keep all the points in one series so that they are drawn properly connected; - Values are coloured according to some quality flag which affects only a few points in the series. So I'd like to keep the default le...

Re: TChartEditor fails to show series format tab

Yeray,

Thanks very much for explaining how to resolve that problem. It works just fine now.

As you said, the 'Themes' tab is now displayed, and it looks as if that's a tab that I can't hide. Is that correct?

TChartEditor fails to show series format tab

Hi, In a simple test project, I add a THistogramSeries, and at design time I can use a chart editor to set colours via the series Format tab. But at run time, the Format tab is missing. And, if I then pick from the chart editor's combo box another series that isn't a THistogramSeries, the chart edit...

Narcis,

Neither link is working for me on multiple machines! Both produce the near empty page shown in the attached image.

Hi, That link to the customer download page does not seem to be working, and from your web page the 'client access' page is also unavailable. As 'support@steema.com' is also no longer valid, it seems I have to post here to report this. Can you advise on how to download the updates please? Regards To...

Re: THistogramSeries % Bar Width

Yeray, Yes, I get the same, but see what happens when you zoom in. The bar width in pixels seems to remain unchanged, so then fills less than 100% of the gap between the adjacent bars either side. When you have a lot of points and zoom in a long way to the detail, the effect is at its worst. That's ...

Re: Scope of TChart.Assign method

Hi Yeray, Thanks for the advice. Actually, I am using the chart Assign method, so I think the ColorPalette is being copied successfully. But that's not the solution either. In a typical use case, the user does this: - He creates a chart and accepts all the default colours. He maybe sets some text ca...

Re: Scope of TChart.Assign method

Yeray, Thanks for the advice. The AssignFormat works very well in all respects except one. If the series uses the default colour assigned automatically at series creation, that colour is not streamed to the saved chart. It then appears that when using the AssignFormat method, the colour of the targe...
