how to draw dynamic marker

[jullrun]

On item onRender script. We can have beforeDrawDataPoint(), beforeDrawMarker() function.
When I change the marker type or color, I would like to depends on others column.
Which means same record on same dataset, but different column.
Is there any method I can get others column value on the same record?

Hi jullrun,

It is a bit tricky to get other column values while in a chart script...however you can do this by adding references inside the Chart Interactivity to the columns you want to use. In the enclosed example, press the Chart Interactivity button on the Value Series of the chart. I have added a reference to row["Minimum"] in the onKeyPress Event. By doing this, I can reference this value in script like dph.getUserValue("row[\"Minimum\"]");
