Chart.js + Template

[ioan]

Something from code:

Code:

datasets: [{
            label: '# Years',
            data: [2020, 2019, 2018],

The easiest way is to use TIWTemplateProcessorHTML with OnUnknownTag event.
In your template you replace "data: [2020, 2019, 2018]" with {$_MYDATA_$} for example and then in TIWTemplateProcessorHTML.OnUnknownTag event you do something like:

Code:

procedure TYourForm.IWTemplateProcessorHTML1UnknownTag(const AName: string; var VValue: string);
begin
  if SameText(AName, '_MYDATA_') then
  begin
    VValue := 'data: [2020, 2019, 2018]'; //<-- you get the values from your db here
  end;
end;

Another way would be to use Custom Content Handlers.
