I have a variable of type List (ArrayList in fact) that contains numbers. How can I plot that numbers in a Bar Chart? What should I enter in Series Category Expression?
Complete story:
I'm using an XML datasource. One of its fields is:
<values>48,59,59,58,53,53,52,55,50,52,54,56,57,59,60,57,56,55,58,62</values>
So I've created a variable with those values splitted like this:
<variable name="arraylist" class="java.util.List"> <variableExpression><![CDATA[new ArrayList<>(Arrays.asList($F{values}.split(",")))]]></variableExpression> </variable>
Now I want to plot the values in a Bar Chart but... what should I write here?
The list of values will always have 20 values (size=20), if that simplifies the problem.
DId it work for yu ? if so can u please share ur jrxml here as I am stuck in same kind of scenario
