Force axis length to match for two graphs

Hi another question please. Is there a way to force a TeeChart axis to have some fixed length. I have a situation with two graphs positioned in panels one above another and would like to have them line up so that time events relative to the same values on the x axis line up. I also need to have a le...

Re: TeeChart FMX and GEOLJSON

Sorry for delay. Been away for a while. Yes, I do mean GeolJson i.e the spatial aware version of JSON. One reason I raise this is that TeeChart VCL anf FMX allow one to import shapefiles but only VCL has a way to read attribute data from associated Dbase file and then only if using BDE type links. I...

TeeChart FMX and GEOLJSON

Does TeeChart support and recognise GEOLJSON format files so as to produce MapSeries graphs? I know that it supports JSON but cannot find any reference to GEOLJSON. If it does, does it then provide access to other attribute fields in the GEOLJSON file? If GEOLJSON is not supported, I would like to a...

Re: Filling within outlines on graphs

Thanks. I am missing something though and am not sure what the associations are. What is the array definition meant to be? is it something like MyArray : array of TPoint; or should this be TPoints, in which case TPoints must be defined in some unit I am not aware of. When adding the pixel location d...

Filling within outlines on graphs

Hi I generate some graphs with elliptical boundaries around data points (see attachment with magenta ellipses). These ellipses represent, say, 1 sigma uncertainties for individual data points. I would like to be able to colour the interior of each ellipse, with variable opacity and maybe gradient ac...

TeeChart for producing alluvial or sankey type plots

Hi
Do you have any plans to add the ability to produce alluvial or sankey type plots in TeeChart? It would be great if you do.

Re: Can't access dataset's

Hi
just to note that I have an identical issue with setting dataset connectivity in design mode, using the latest binary install version of TeeChart FMX with Delphi 10.3.

Everything works fine if I define the connections at runtime in my code.

Regards
Bruce
