Zooming and scrolling

[Petr]

Hello,
When i'm using axis scroll with zoom direction property turned to horizontal, it zooms in and out( dependently on direction ) every time i'm trying to scroll axis.
At the same time, when zoom direction turned to both this zooming don't have place. What should i do to turn this zooming off?

Hello Ptr,

I inform you if you want turn off the zoom, you only need set the zoom allow property to false as do in next line of code:

Code: Select all

tChart1.Zoom.Allow = false; 

On the other hand, I have made a simple code using Axis Scroll Tool and zooming direction to horizontal and your problem isn't produced by me:

Code: Select all

    public Form1()
    {
      InitializeComponent(); 
      InitializeChart();
    }
    private void InitializeChart()
    {
      tChart1.Aspect.View3D= false; 
      Steema.TeeChart.Styles.Line line1 = new Line(tChart1.Chart);
      line1.FillSampleValues();
      Steema.TeeChart.Tools.AxisScroll scroll = new AxisScroll(tChart1.Chart);
      scroll.Axis = tChart1.Axes.Bottom;
      tChart1.Zoom.Direction = ZoomDirections.Horizontal; 
     }

Could you tell us which version of TeeChartFor.Net are you using? My code works in your end? If your problem persist, please indicate exactly how can reproduce it here or arrange for us a simple project, where this problem appears.

I hope will helps.

Thanks,

Hi sandra, thanks for reply, i'm using "Steema TeeChart for .NET 2012 4.1.2012.01310". Unfortuantely i don't want to turn zoom off at all. And I still have this problem. I found, that then zom direction is horizontal, when i'm scrolling axis(bottom) it hapens zoom event(which is overrided ), and then it turned to both - not. So the algorythm oz zooming is different, and i cant use Horizontal zooming as is. So, as i told before i use zooming in both direction, that is ok for me, because i use only Custom vertical axes(so i don't have vertical zooming basicaly) . But i would like to make a selection style, like it is made in case of horizontal zoom direction( Like a strip, with variable width). Are there any ways how can i do it?
