Load an image from a file and use it as the graphics symbol to plot the data points.
ChartDirector will automatically detect the image file format using the file extension, which must either png, jpg, jpeg, gif, wbmp or wmp (case insensitive).
Please refer to BaseChart.setSearchPath
on the directory that ChartDirector will search for the file.
In the current version of ChartDirector, data symbols are supported only in LineLayer
. To use data symbols in other layer types, add a ScatterLayer
on top of that layer.
