View Full Version : Having trouble displaying the line graph.

10 Apr 2012, 9:40 AM
I am having trouble displaying the line graph properly. &nbsp;I have a Json store and I am able to display a grid, bar chart and pie chart without any issue. &nbsp;The line graph is a straight line from 0,0 to 5,5. &nbsp;Attached is the output of the html page. &nbsp;Please let me know what is it I am missing. I removed the code for bar chart and piechart.<br><br>

Since you are using Numeric axis, the Number of Opportunities data should be a number not a string:

var store = Ext.create('Ext.data.JsonStore', {
fields: ['User Name','Number of Opportunities'],
data: [
{'User Name':'chris','Number of Opportunities':14},
{'User Name':'jim','Number of Opportunities':3},
{'User Name':'maxx','Number of Opportunities':22},
{'User Name':'sally','Number of Opportunities':26},
{'User Name':'sarah','Number of Opportunities':5},
{'User Name':'will','Number of Opportunities':12}

Hi Mitchell,

Thank you for pointing that out. Feel dumb making such a silly mistake. :">

As the bar chart was working without any issue, I was expecting line to behave the same.

Thanks again,
