Implementation of multi-type Polygon Chart in pure JavaFX. This project was created due to lack of JavaFX default charts and for previous projects needs.
You can clone this project and build it by yourself, or you can grab the pre-build jar library and import it directly into your project and you are ready to go.
Creating a new chart:
String categories[] = { " Category A", "Category B", "Category C", "Category D", "Category E", "Category F"};
// new PolygonChart(width, height, numberOfTicks, categories, minValue, maxValue)
PolygonChart chart = new PolygonChart(485, 400, 4, categories, 0, 10);The shape of the chart depends on number of categories you will pass as an argument into the constructor. You have create any kind of polygon for example (Image resolution is been reduced to fit the page ) :
Adding value to a chart:
double values[] = { 5, 2, 8, 6, 9 };
chart.setValues(values);Note : you have to add a value for each category so if the number of categories is 5 then you have to pass a double[5] to the setValue() method.
And you are able to aply more values on chart with different colors and opacity :
The values insertions is animated and can be deactivated if you want by calling
chart.setAnimation(false); -
The chart is not optimized in process of redrawing everything, but this is not really a problem and it will be fixed soon.
-
In addition, there is no way to change the five first default colors of the polygons on the chart but a new method will be added soon. If you want to do that you will have to clone the entire project and change it by yourself.
-
The chart will scale with its parent dimensions by default, sometimes if the parent's dimensions are not very wide the chart might look weird so you will have to specify the min max and preferred dimensions to have a nice look.
