Tip : Disable yAxis values for column or bar of highcharts in jasper reports

Hi,

Problem Statement : 
How to remove yAxis values from  a highcharts column or bar graph ?

Solution: 
1) Navigate to the Advanced properties of the column graph.
2) From the list of folders in the advanced properties choose "yAxis" and expand it.
3) Scroll down till you find again a folder called "lables".
4) In the labels folder select "format" property (by default it would have default value as {value}) and double click or click on modify button.
5) Change the value of it from {value} to {}
6) Save your report and preview the the visualization
 

Output should look like as below

I hope this helps someone.
