Re: Can't implement Totals using C++

Hello Patricio, Apologies for having left you unattended with you query. For the record; an example of implementation of totals by code in C++ would be as follows: #include "Tee.Grid.Totals.hpp" TGridFooter *footer = TeeGrid1->Footer; TColumnTotals *totals = new TColumnTotals(footer); totals->Calcul...

Re: Calculation of totals (incorrect examples)

At the moment this is what I see as working correctly, see https://github.com/Steema/TeeGrid/blob/master/demos/VirtualData/Array/Unit_Array.pas // Setup grid Footer bands var tmp : TColumnTotals; TeeGrid1.Footer.Clear; tmp:=Totals(TeeGrid1.Footer); calls: // Ret...

Re: TeePoly epsilon value

Hello, Thanks for the update. After reviewing this, it seems that the result-sensitivity could be affected according to the data content itself with respect to error condition being 1e-19 or 1e-15 (32 or 64 bit). Perhaps there's scope here for error to be a developer controlled variable. We'll consi...

Re: DownSampling

Hello Scott, On closer examination the points plotted from DisplayedPointCount is not perfectly fixed according to total plotted points. There is a fixed tolerance that brings the display points down after a certain point. When tested on a 100,000 point series with a DisplayedPointCount at 1,000, th...

Re: Power Values are showing too far in the Bottom-Axis.

Hello,

This looks like a formatting bug. It's been added to the system to be fixed.

Re: DownSampling

Hello Scott,

We're checking this. on simple tests it seems ok, but I can see a problem when testing the new down-sample to be introduced with the next version, Douglas-Peucker. We'll do an overall check whilst we're reviewing that.

Re: Legend customization for color grid

Hello Sravan, You could use the ongettext event. In this case only putting the text label in for every second value: //chart setup code...etc, then: Chart1.legend.ongettext=function(legend,series,index,res) { if (index % 2 != 0) return res; else return ""; } //more code of choice then: Chart1.draw()...

Hello, You could create a new toolbox tab and choose items, browsing for the new dll. The original tab will then not be visible but is still there. The new tab/items could be removed after the test to reshow the original tab. Alternatively.... Remove the reference to the existing teechart.dll from y...

Re: Issue with export to EMF/WMF on high DPI displays

Hello,

With respect the DPI question, please take a look at this thread:

viewtopic.php?f=3&t=16959#p75510

The example code is written for Delphi but the principle is the same applied to the TeeChart ActiveX control.

Re: Color grid legend and Min and Max values of series

Hello Sravan, You're switching in the Series one by one? To change the min or max of a series array you'll need to scan the array for the two values and replaced them at their index position. If there is more than one occurrence of the value you only need to modify one of them. I do get the feeling ...
