Obtaining the visual feature object

In order to change a visual property , you must first obtain it from the category object. You can obtain it by it’s name with the GetVisualProperty method.

            var cat = chart.DataSource.GetCategory("dataseries-1");

            //obtain the point visual property
            var point = cat.GetVisualFeature<GraphPointVisualFeature>("Graph Point-0");
            //obtain the fill visual property
            var fill = cat.GetVisualFeature<GraphFillVisualFeature>("Graph Fill-0");
            //obtain a line visual property
            var line = cat.GetVisualFeature<GraphLineVisualFeature>("Graph Line-0");

Changing the properties of a visual feature

The properties in the object correspond with the properties in the inspector. To learn more about them see the visual feature refrence

// point feature
            point.PointSize = Random.value * 1f + 1f;

// fill feature
            fill.CanvasSortOrder = Random.value > 0.5 ? -1 : 1;
            fill.FillMaterital = Random.value > 0.5 ? Fill1 : Fill2;
// line feature
            line.LineThickness = 5f;
