About Custom Axis

[johnnix]

Hello,

I have a chart where I am using a custom axis. I use the OnClickAxis event and I cannot find any way to know that the axis I clicked is the custom Axis. Any help will be mostly appreciated

Kindest regards

Hi johnnix,

The following code seems to work fine.

Code: Select all

procedure TForm1.Chart1ClickAxis(Sender: TCustomChart; Axis: TChartAxis;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var i: Integer;
begin
  for i:=0 to Chart1.Axes.Count-1 do
    if (Axis = Chart1.Axes[i]) then showmessage('clicked ' + IntToStr(i));
end;

Could you please send us a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Hello Yeray,

Maybe I was not clear enough What I need to do is to identify that the axis I clicked is my custom axis. In the ClickAxis event I can check the Horizontal property of Axis to determine if it is the X or Y axis but there is no property like IsCustom!!! Is this clear?

Hello,

Just figured out that Axis.Index is -1 for default axis so by checking this value I know if I clicked on the custom Axis.

Hi johnnix,

I'm glad to see that you've found it! Thanks for sharing.

Hello Yeray,

No problem, just consider adding a property e.g. IsCustom !!!

Hi jonnyx,

There is already a private IsCustom function but making it public needs some adjustments because right now it fails if you remove some of the default axes.
I've added it to the wish list to be revised for further releases (TV52014703).
