IW 15.5.9 IWChart

[PaulWeem]

Hi Alexandre,

As of IW 15.5.9 it's not possible anymore to create a Chart where one serie is of type ctLine and the second serie is of type ctBar.
All serie are shown as the type set in the ChartType property (at design- or runtime).

Furthermore, I'm still looking for a way to save the Chart to an image, so it can be used in a report.

Hope you can help with this.

I'm using Delphi 12(.1).

Cheers, Paul

Is this still an issue as of 15.6.0? - I'll be playing with this Chart shortly, so I'm interested to know if it has been fixed yet...

Hi iwuser,

This issue still exists in 15.6.0.
I too hope it will be addressed soon.

Cheers, Paul

Hi Alexandre,

I'm afraid this problem still exists in IW 15.6.1.
Also, rendering colors when ChartType = ctLine doesn't work as expected.

Can you please have a look at this?

Thank you, Paul

Hi am using Delphi 10.2, what works in 15.5.9 now raise an error as below and program can't be compiled:

[dcc32 Error] E2251 Ambiguous overloaded call to 'Add'
IWChartJS.pas(1): Related method: function TChartData.Add(TDateTime): TChartData;
IWChartJS.pas(1): Related method: function TChartData.Add(Double): TChartData;

Just to update, once I have removed the round() function and return the value back to double, the errors went away for v15.6.1. It seems before at v15.5.9 integer was ok for adding as value to ChartJS, eg, CustChartJS.MainSeries.Add(Round(value)). Now it only accepts double else error will occur (Ambiguous overloaded call to 'Add'). Cheers.
