Scatter plot with tens of thousands points

When a chart has a lot of data, it might get slow, especially if you use a separate object, like a bullet for each data item. Each object uses part of the memory so at some point your chart’s performance will get worse. In many such cases there is a solution which will extend amCharts possibilities to display huge data sets many times: instead of creating a separate Bullet object for each data item, we create a single Graphics object and use default drawing capabilities to draw required shapes into this Graphics. You can draw any shape there.
