title: Issue relate to sencha touch bar charts
body: <p>I am very new to sencha touch. Working with sencha touch to develop bar charts. I am an issue regarding the bar width of the chart. As the number of bars get increased the bar width gets decreased. But the thing is it should not happen like that. The bar width must be fixed even if the bars get increased also. I will apply scroll bar to see the reamining bars plotted on the graph. Scroll bar is not issue. But how do I fix the bar width of the bar chart. Could anyone share the solution for this issue ASAP.</p>
  
  <p>Thank in advance.</p>
