I have an HTML5 chart in my report and I want to set the default type from a parameter, but still allow the gear-dropdown to change the type afterwards.
I am using Visualize.js to embed my report into another application.
My jrxml defines the chart in this way:
<hc:chart type="Pie" xmlns:hc="http://jaspersoft.com/highcharts" xsi:schemalocation="http://jaspersoft.com/highcharts http://jaspersoft.com/schema/highcharts.xsd">
Where chartTypeParam is the parameter passed into the report.
This works fine to set the default type of the chart. But when I then use the gear menu dropdown in the rendered report to change the type, it just reloads with the same value that was passed in as a parameter.
I want the parameter to define only the default, and still allow the user to select a new type afterwards.
I can get around this problem by making a copy of the chart element for every type I want, then hiding all but one chart as specified by the parameter, but that is horrific and unmaintainable. I would have to have the same configuration code 6 different times.
Any advice would be helpful.
