Forgot to say - thank you!

My request to servicedesk is almost fulfilled:

Visual selection of parameters from optimisation results.

Suggestions, MetaTrader 5 Client, Closed, Started: 2011.11.24 17:52, #276278

Problem description

It is difficult to select the optimal one from all optimisation results from the user's point of view.

Suggestion:

1 In the tab "Optimisation results" introduce the possibility of using filters, such as "Profit from... and up to...", "Trades from.... and up to...", etc.

2 Introduce the possibility of simultaneous viewing of equity/balance graphs of pre-selected parameters in the "Optimisation Results" tab. Of course, the equity/balance graphs should not be stored for each set of parameters (it would be too costly), but should be run separately through the history at the request of the command "Display equity/balance graph".

3 Consider the standard possibility of building Kohonen maps based on the results of optimisation.

Expected result

There will be a possibility to choose a "more optimal" variant of the Expert Advisor parameters according to the researcher's opinion taking into account many criteria in visual mode.

Refused to work in build.674 from 12.07.

Please correct it.

In the CCanvas class the FillRect() method was renamed to FillRectangle(). It is enough to make the same replacement of the method name in the method of the CSpecialChart::Update class.

void CSpecialChart::Update(void)
  {
//--- fill in the background
   CCanvas::Erase(CSpecialChart::uCLR(m_bkgroundcolor));
//--- draw the frame
   CCanvas::FillRectangle(m_framewidth,m_framewidth,
                          m_width-m_framewidth-1,
                          m_height-m_framewidth-1,
                          CSpecialChart::uCLR(m_framecolor));

Fixed.

There are still 2 errors:

I can't understand that width is converted to int type everywhere.

The error occurs both at home and on a newly installed terminal at work.

Replace

in line 63 of the ColorProgressBar.mqh file "CCanvas::Create" to "CCanvas::CreateBitmapLabel"

replace "m_spec_chart.Create" with "m_spec_chart.CreateBitmapLabel" in line 70 of the FrameGenerator.mqh file

Thank you everything works now!

I found the paths by searching.

but I don't know if these are the latest versions. logically they are the latest.
