Zooming may ignore x-axis labels

Post by Jared Cooper » Thu May 08, 2014 12:38 pm

I have a very simple JS chart, including:

Series0.data.x=[1,2,3,4,5,6,7,8,9,10,11];
Series0.data.values=[1,2,3,2,4,3,2,5,2,2,0];
Series0.data.labels=["01/01/2000","02/01/2000","03/01/200","04/01/2000","05/01/2000","06/01/2000","07/01/2000","08/01/2000","09/01/2000","10/01/2000","11/01/2000"];

When zooming with the mouse, once you zoom in far enough (not far in this simple example) the x-axis starts showing 1.2, 3.4, etc - it's ignoring the labels and showing a partial value between the x values.

This is also true if the Series0.data.x... line is removed, so only values and labels are included.

Is there any way to prevent this?

Hello,

You could play with the zoom events and the increment. Ie:

Code: Select all

  Chart1.onzoom=function() {
    Chart1.axes.bottom.increment=(Chart1.axes.bottom.increm<=1)? 1:0;
  }
  
  Chart1.zoom.onreset=function() {	
	Chart1.axes.bottom.increment=0;
  }
