Aspose.Slides可以帮助开发人员实现幻灯片的创建、编辑、读取和转换等操作，在创建幻灯片的时候为了更清晰和直观的分析数据，很多时候需要在幻灯片里添加各种图表，为了图表更美观和直观还需要对图表中的各种元素进行格式化设置，
Aspose.Slides为广大开发人员提供了强大的API来格式化图表中的轴刻度线、表格线、轴标签格式化、设置坐标轴的最大、最小值、坐标轴的标题、图表的背景色、填充色、图例的设置等多种图表元素的格式化，具体使用方法可以查看下面的Java代码：
// Instantiating presentation
Presentation pres = new Presentation();
// Accessing the first slide
ISlide slide = pres.getSlides().get_Item(0);
// Adding the sample chart
IChart chart = slide.getShapes().addChart(ChartType.LineWithMarkers, 50, 50, 500, 400);
