 multiple plot areas on a single chart |

Hi,
Is there a way to have several plot areas on a single chart, in order to display additional graphs with the same X axis. This would look similar to what is available on Finance charts. Or do I necessarily have to create several charts in the in the same viewer?
Thanks in advance |

Hi Bruno,
The only method in ChartDirector is to use a MultiChart. A MultiChart is a container that can contain multiple XYChart objects. The FinanceChart is derived from MultiChart. That's why it can have multiple plot areas.
The following is an example that shows a real-time zoomable MultiChart.

Thank you, Peter
I didn't know about the MultiChart feature.
Looking forward to your sample app as I couldn't find one in the demo solution. |

Hi BRUNO,
Sorry, I forgot to include the link. It is an example that comes with ChartDirector 7.

There is another example that is available even in very old versions of ChartDirector. It puts the two XYCharts side by side (instead of top-down):

Basically, your code can creates multiple XYChart objects, and then add them to the MultiChart object.
XYChart c1 = new XYChart(.....);
......
XYChart c2 = new XYChart(.....);
......
XYChart c3 = new XYChart(.....);
......
MultiChart m = new MultiChart(totalWidth, totalHeight);
// Add the XYChart objects to the MultiChart at any position you like
m.addChart(x1, y1, c1);
m.addChart(x2, y2, c2);
m.addChart(x3, y3, c3);
// Display the MultiChart
viewer.Chart = m;
Best Regards

Thank you Peter, much appreciated!
Maybe worth adding a "MultiChart" tree node in your sample app for people like me...
Cheers
