I drew a 3D line chart using jfree.chart3d in the Orson Charts library using java. How can I get the data between two points selected with the mouse on the line chart I drew?
I searched deeply but get no getDataset() or similar methods in the library. I try to get the line plot at the clicked point with the mouse but found no such method. Any help would be appreciated. There are solutions on 2D charts but I have not come across such a solution for jfree.chart3d library
I try to read the dataSet among the line charts selected by mouse. First mouse click defines the start point of the sub-line, and second mouse click defines the end point of the sub-line of the line selected by mouse. I tried to read the dataSet as follows. But I get "getRenderer() is undefined for type Plot3D" error. Here are my questions:
1.How can I highlight the selected line plot, so that to create awareness to the user that he/she has chosen the right plot among other plots?
2.How can I get the selected line plot's dataSet?
3.How Can I obtain the sub-dataSet between two mouse clicks on the selected line plot?
Here is the complete code:
