Hi,
I have a problem, I do not seem to able to use scatterctrl.
I have a tabctrl. I have a layout which contains scatterctrl.
Layout is added to the tabctrl.
Vector<Pointf> data_equity,data_balance;
performance.chart.RemoveAllSeries();
for (int i=0; i< order_history.order_info.GetCount();i++)
{
data_equity << Pointf(i,order_history.order_info.Get(i,7));
data_balance << Pointf(i,order_history.order_info.Get(i, );
}
performance.chart.AddSeries(data_balance).Legend("balance");
performance.chart.AddSeries(data_equity).Legend("equity").Units( "km/h").NoMark().Stroke(2, Gray()).Dash(LINE_SOLID).Fill(LtGray());;
/
if I add series , it crashes when I switch to the tab which contains the scatterctrl.
case WM_PAINT:
ASSERT_(!painting || IsPanicMode(), "WM_PAINT invoked for " + Name() + " while in Paint routine");
ASSERT(hwnd);
if(hwnd) {
PAINTSTRUCT ps;
It fails for M_PAINT invoked for " + Name() + " while in Paint routine");
I use the latest upp.

Hello aftershock
In addition, please remember that ScatterDraw does not keep any data, so data has to be kept safely.
For example, if data is declared in a function that fills the Scatter, and if you need the Scatter after leaving the function, you will get errors as Scatter will try to use data that has been freed.
Best regards
Iñaki
