Axis Breaks and corrupt axis labels

[Philipp P.]

Hello,

I am using the AxisBreak tool to mask out certain areas of my chart on the x-axis using multiple axis breaks, each with GapSize = 30. In most cases the axis breaks mess up my x-axis labels and it seems that multiple labels get overdrawn then (see image attachment)... Is there any way to avoid this?

Thanks in advance
Philipp

Hi Philipp,

Can you please attach a simple example project we can run "as-is" to reproduce the problem here? A general option could be using custom axis labels as in the All Features\Welcome !\Axes\Labels\Custom labels example at the features demo available at TeeChart's program group.

Thanks in advance.

Hi Narcís,

The problem occurs with different gapsizes and x-axis ranges... I could reproduce the problem with the following small sample application:

Code: Select all

namespace GuiTestbench
{
  partial class MainForm

    /// <summary>

    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
      if (disposing && (components != null))
      {
        components.Dispose();
      }
      base.Dispose(disposing);
    }

Hello Pilipp P.

The problem of overlaping of AxisBreaks can be solved of many ways,e.g:

1.- Changing the size of GapSize, adapting it to your labels space.
2.- Changing the scale of Axes.
3.- Changing the angle of labels.
4.- Using custom labels, etc.

Basically, you need treat this problem as you treat anyone of problems to overlap as do in this thread.

I hope will helps.

Thanks,
