I got the chart shown in the image, it is filled with a CategoryModel and I would like to append "%" to every value. My code is:

private Charts chartCumplimientoPDV;
CategoryModel model = new DefaultCategoryModel();
//Here there is some code that fills model using model.setValue(,,,)

I think that I have to do something like this, but I only get "%" without values:

linePlotOptions = chartCumplimientoPDV.getPlotData().getPlotOptions().getLine();


Thank you,

Based on the highcharts demo the format strings should be like this {y}%

I tried the {point.value} as described in their docs which doesn't seem to work, maybe the docs aren't up to date.

Where did you find the {item.value} syntax?

I tried point.value also but I think that this only works when the model is composed by Point.

I did not find item.value anyway, it only was one of my options because I set the different values of CategoryModel with: setValue(series, category, value); https://www.zkoss.org/javadoc/7.0.3/zk/org/zk

so you try the {y}% pattern? BTW which ZK/ZKCharts version are you using?

the following works using ZK 9.1.0 and ZKCharts


    <charts width="400" height="300" title="test" apply="ChartComposer"/>


import org.zkoss.chart.Charts;
import org.zkoss.chart.model.DefaultCategoryModel;
import org.zkoss.chart.plotOptions.LinePlotOptions;
import org.zkoss.zk.ui.util.Composer;

public class ChartComposer implements Composer<Charts> {
    public void doAfterCompose(Charts chart) throws Exception {
        DefaultCategoryModel model = new DefaultCategoryModel();
        model.setValue("Pork", "2018", 25.3);
        model.setValue("Pork", "2019", 19.2);
        model.setValue("Pork", "2020", 30);
        model.setValue("Beef", "2018", 74.7);
        model.setValue("Beef", "2019", 80.8);
        model.setValue("Beef", "2020", 70);
        LinePlotOptions linePlotOptions = chart.getPlotOptions().getLine();
