Monochrome option and psDash interspace

hi,
On a canvas, I set for the LeftAxis and BottomAxis axes, a Grid with psDash
BottomAxis.Grid.Style = psDash
If I print with Monochrome option, the grid appears as a straight line.
Can one control the interspace for the Dash, and if so which option shall I use here?
Many thanks for your valuable help

Hello Nabil,

I've made a simple example printing a chart to a virtual pdf printer and I can see the dashed style in the bottom axis grid.
Here the code:

Code: Select all

uses Series, TeeEdiGene;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Chart1.Monochrome:=true;
  ChartPreview(nil,Chart1);
  Chart1.Monochrome:=false;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.Legend.Visible:=false;

  Chart1.AddSeries(TBarSeries).FillSampleValues;
  Chart1.Axes.Bottom.Grid.Style:=psDash;
end;
And here the pdf I get:

hi Yeray,
many thanks for your reply.
I certainly did not describe accurately the issue I have to deal with here and which is illustrated on the attached plot on which I need to have a grid.
My point is to know whether one can control the dashes frequency aka the gap between two consecutive dashes of one grid line.
basically, can one go from:

Code: Select all

_  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _ 
_  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _ 
_  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _  _ 
to (a larger gap)

Code: Select all

_    _    _    _    _    _    _    _    _    _    _    _    _    _
_    _    _    _    _    _    _    _    _    _    _    _    _    _
_    _    _    _    _    _    _    _    _    _    _    _    _    _
Is this supported at all? I had a careful look at the Grid properties, but did not come to any improvement.
Note that, the file is saved as WMF (If I use BMP, the plot quality is worse)
thanks!
