Chart size and position

[Francesco Grassi]

Hello, 

may i ask why i can't set the height, width and position of a chart after opening it?

This is the code i use:

// General Variables
bool ChartSetInteger();


// function
void OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam)
  {
  if(id==CHARTEVENT_OBJECT_CLICK && ObjectGet(sparam,OBJPROP_TYPE)==OBJ_BUTTON)
      {
      long idchart=ChartOpen(ObjectGetString(0,sparam,OBJPROP_TEXT),PERIOD_M15);
      ChartApplyTemplate(idchart,"Default");
      ChartSetInteger(idchart,CHART_WIDTH_IN_PIXELS,800);
      ChartSetInteger(idchart,CHART_HEIGHT_IN_PIXELS,500);
      }

I also tried to use WindowRedraw(); and tried to write a different indicator just with  

ChartSetInteger(idchart,CHART_WIDTH_IN_PIXELS,800);
ChartSetInteger(idchart,CHART_HEIGHT_IN_PIXELS,500);

to put directly on the new opened chart but nothing works!

Thanks.

Read the help. These are read-only chart properties:

CHART_WIDTH_IN_PIXELS	Chart width in pixels	int r/o
CHART_HEIGHT_IN_PIXELS	Chart height in pixels	int      modifier - subwindow number

Thanks.

You can GET the dimensions of the graph. You cannot SET the dimensions of the graph (if we are talking about standard graphics).

But you can create a graph - a graphic object ( OBJ_CHART ) and then you can control the size (example inside the help)

Thanks for the explanation.

With "if we are talking about standard graphics" you mean that i could achieve this using external libraries?

Read above. I said everything and gave examples. I also highly recommend reading the help.

By the way, take a look at the new charting functions: (applies to real charts)

CHART_IS_DOCKED	The chart window is docked. If set to false, the chart can be dragged outside the terminal area	bool
CHART_FLOAT_LEFT	The left coordinate of the undocked chart window relative to the virtual screen	int
CHART_FLOAT_TOP	The top coordinate of the undocked chart window relative to the virtual screen	int
CHART_FLOAT_RIGHT	The right coordinate of the undocked chart window relative to the virtual screen	int
CHART_FLOAT_BOTTOM	The bottom coordinate of the undocked chart window relative to the virtual screen	int

Thank you very much for the info mate. I'll make some tests when i'm free from work.

Bytheway i try to read the help but sometimes i just don't know what to look for :)

Have a nice day.
