TDBChart Save design and load back?

Post by C-P » Mon Jan 18, 2021 4:13 am

Working on a user configurable "dashboard" system. Idea is to allow them to design their query, run it, then design a TDBChart
to hook into that and design their chart. Also I have it so they can design a grid view design and some other stuff for this "dashboard" system.

I have VCLTee.TeeEditPro, VCLTee.Teestore in the uses.

Delphi 10.3.2 with TeeChart v2020.31.201112 PRO edition

I tried to save to XML first. Which was nice as pretty easy to read with vcltee.TeeStore.SaveChartToFile

but there is no version of this to LOAD from xml.

vcltee.Teestore.LoadChartFromFile only exists, and this does only .TEE files.

So.. I switched to trying to load the .TEE file.

So in this case after it is saved I clear or close program.

I open it back up and run my query.
Then I load my saved off .TEE file. Which generates no error.
But I have nothing in my TChart. The series is there, but the Data side of things did not apply.
I have to bring up the TChart editor and I see my series is back but when I goto the data tab nothing is applied back.

I don't want to save the data. I just want to save the whole design of the TDBChart after a user configures it up against a query they run.
Then bring it backup later from a saved file.

Any ideas?

I kinda got this to work via something like this

Code: Select all

procedure TForm8.Button3Click(Sender: TObject);
begin
  VclTee.Teestore.LoadChartFromFile(DBChart1, 'gadget1.tee');
  if DBChart1.SeriesCount = 1 then
    DBChart1.Series[0].DataSource := q_Gadget; /// <--- TADOQuery object, once assigned, boom it works.
end;
Once I assign the series datasource manually after loading the .TEE file, then it works.

Looking at the .TEE file created, the datasource there does exist, with q_Gadget as its value to point to.
Bug or am I missing something?

Code: Select all

object TDBChart
  Left = 1
  Top = 1
  Width = 478

Indeed, that's already in the public tracker #2390.

That was also identified time ago here #185.

Oof ok... So the XML report is pretty new. 2020-12-04.

The other one for the dataset issue was reported in 2010-03-19.

Well hopefully my work around for this for now will get me by.
